6. Which command displays the SQL command in the SQL buffer, and then executes it?
RUN

7. What are the wildcards used for pattern matching?
_ for single character substitution and % for multi-character substitution

8. State true or false. EXISTS, SOME, ANY are operators in SQL.
True

9. State true or false. !=, <>, ^= all denote the same operation.
True

10. What are the privileges that can be granted on a table by a user to others?
Insert, update, delete, select, references, index, execute, alter, all

11. What command is used to get back the privileges offered by the GRANT command?
REVOKE

12. Which system tables contain information on privileges granted and privileges obtained?
USER_TAB_PRIVS_MADE, USER_TAB_PRIVS_RECD

13. Which system table contains information on constraints on all the tables created?
USER_CONSTRAINTS

14. TRUNCATE TABLE EMP;
DELETE FROM EMP;
Will the outputs of the above two commands differ?
Both will result in deleting all the rows in the table EMP.

15. What is the difference between TRUNCATE and DELETE commands?
TRUNCATE is a DDL command whereas DELETE is a DML command. Hence DELETE operation can be rolled back, but TRUNCATE operation cannot be rolled back. WHERE clause can be used with DELETE and not with TRUNCATE.

16. What command is used to create a table by copying the structure of another table?
Answer :
CREATE TABLE .. AS SELECT command
Explanation :
To copy only the structure, the WHERE clause of the SELECT command should contain a FALSE statement as in the following.
CREATE TABLE NEWTABLE AS SELECT * FROM EXISTINGTABLE WHERE 1=2;
If the WHERE condition is true, then all the rows or rows satisfying the condition will be copied to the new table.

17. What will be the output of the following query?
SELECT REPLACE(TRANSLATE(LTRIM(RTRIM('!! ATHEN !!','!'), '!'), 'AN', '**'),'*','TROUBLE') FROM DUAL;
TROUBLETHETROUBLE

18. What will be the output of the following query?
SELECT DECODE(TRANSLATE('A','1234567890','1111111111'), '1','YES', 'NO' );
Answer :
NO
Explanation :
The query checks whether a given string is a numerical digit.

19. What does the following query do?
SELECT SAL + NVL(COMM,0) FROM EMP;
This displays the total salary of all employees. The null values in the commission column will be replaced by 0 and added to salary.

20. Which date function is used to find the difference between two dates?
MONTHS_BETWEEN

21. Why does the following command give a compilation error?
DROP TABLE &TABLE_NAME;
Variable names should start with an alphabet. Here the table name starts with an '&' symbol.

22. What is the advantage of specifying WITH GRANT OPTION in the GRANT command?
The privilege receiver can further grant the privileges he/she has obtained from the owner to any other user.

23. What is the use of the DROP option in the ALTER TABLE command?
It is used to drop constraints specified on the table.

24. What is the value of ‘comm’ and ‘sal’ after executing the following query if the initial value of ‘sal’ is 10000?
UPDATE EMP SET SAL = SAL + 1000, COMM = SAL*0.1;
sal = 11000, comm = 1000

25. What is the use of DESC in SQL?
Answer :
DESC has two purposes. It is used to describe a schema as well as to retrieve rows from table in descending order.
Explanation :
The query SELECT * FROM EMP ORDER BY ENAME DESC will display the output sorted on ENAME in descending order.

26. What is the use of CASCADE CONSTRAINTS?
When this clause is used with the DROP command, a parent table can be dropped even when a child table exists.

27. Which function is used to find the largest integer less than or equal to a specific value?
FLOOR

28. What is the output of the following query?

JOB INTERVIEWS DOs and DON'Ts

JOB INTERVIEWS DO's and DONT's

Here are the keys to successful job interviewing.
Follow these simple rules and you should achieve success in this important phase of job-hunting.

• Do take a practice run to the location where you are having the interview -- or be sure you know exactly where it is and how long it takes to get there.

• Do your research and know the type of job interview you will be encountering. And do prepare and practice for the interview, but don't memorize or over-rehearse your answers. Do dress the part for the job, the company, the industry. And do err on the side of conservatism. If you're not sure, you should consider reading our article.

• Do plan to arrive about 10 minutes early. Late arrival for a job interview is never excusable. If you are running late, do phone the company.

• Do greet the receptionist or assistant with courtesy and respect. This is where you make your first impression.

• Don't chew gum during the interview.

• If presented with a job application, do fill it out neatly, completely, and accurately.

• Do bring extra resumes to the interview. (Even better, if you have a job skills portfolio, do bring that with you to the interview.)

• Don't rely on your application or resume to do the selling for you. No matter how qualified you are for the position, you will need to sell yourself to the interviewer.

• Do greet the interviewer(s) by title (Ms., Mr., Dr.) and last name if you are sure of the pronunciation. (If you're not sure, do ask the receptionist about the pronunciation before going into the interview.

• Do shake hands firmly. Don't have a limp or clammy handshake!

• Do wait until you are offered a chair before sitting. And do remember body language and posture: sit upright and look alert and interested at all times. Don't fidget or slouch.

• Don't tell jokes during the interview.

• Do make good eye contact with your interviewer(s).

• Do show enthusiasm in the position and the company.

• Don't smoke, even if the interviewer does and offers you a cigarette. And don't smoke beforehand so that you smell like smoke. And do brush your teeth, use mouthwash, or have a breath mint before the interview.

• Do avoid using poor language, slang, and pause words (such as "like," "uh," and "um").

• Don't be soft-spoken. A forceful voice projects confidence.

• Do have a high confidence and energy level, but don't be overly aggressive.

• Don't act as though you would take any job or are desperate for employment.

• Do avoid controversial topics.

• Don't say anything negative about former colleagues, supervisors, or employers.

• Do make sure that your good points come across to the interviewer in a factual, sincere manner.

• Don't ever lie. Answer questions truthfully, frankly and succinctly. And don't over-answer questions.

• Do stress your achievements. And don't offer any negative information about yourself.

• Don't answer questions with a simple "yes" or "no." Explain whenever possible. Describe those
things about yourself that showcase your talents, skills, and determination. Give examples.

• Do show off the research you have done on the company and industry when responding to questions.

• Don't bring up or discuss personal issues or family problems.

• Do remember that the interview is also an important time for you to evaluate the interviewer and the company she represents.

• Don't respond to an unexpected question with an extended pause or by saying something like, "boy, that's a good question." And do repeat the question outloud or ask for the question to be repeated to give you a little more time to think about an answer. Also, a short pause before responding is okay.

• Do always conduct yourself as if you are determined to get the job you are discussing. Never close the door on an opportunity until you are sure about it.

• Don't answer cell phone calls during the interview, and do turn off (or set to silent ring) your cell phone and/or pager.

• Do show what you can do for the company rather than what the company can do for you.

• Don't inquire about salary, vacations, bonuses, retirement, or other benefits until after you've received an offer. Be prepared for a question about your salary requirements, but do try and delay salary talk until you have an offer. (You might consider visiting our salary tutorial for more tips and strategies.)

• Do ask intelligent questions about the job, company, or industry. Don't ever not ask any questions -- it shows a lack of interest.

• Do close the interview by telling the interviewer(s) that you want the job and asking about the next step in the process. (Some experts even say you should close the interview by asking for the job.)

• Do try and get business cards from each person you interviewed with -- or at least the correct spelling of their first and last names. And don't make assumptions about simple names -- was it Jon or John -- get the spelling.

• Do immediately take down notes after the interview concludes so you don't forget crucial details.

• Do write thank you letters within 24 hours to each person who interviewed you.

JAVA QUESTION & ANSWERS PART-I

FREQUENTLY ASKED JAVA QUESTIONS WITH ANSWERS

1.what is a transient variable?
A transient variable is a variable that may not be serialized.

2.which containers use a border Layout as their default layout?
The window, Frame and Dialog classes use a border layout as their default layout.

3.Why do threads block on I/O?
Threads block on i/o (that is enters the waiting state) so that other threads may execute while the i/o Operation is performed.

4. How are Observer and Observable used?
Objects that subclass the Observable class maintain a list of observers. When an Observable object is updated it invokes the update() method of each of its observers to notify the observers that it has changed state. The Observer interface is implemented by objects that observe Observable objects.

5. What is synchronization and why is it important?
With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources. Without synchronization, it is possible for one thread to modify a shared object while another thread is in the process of using or updating that object's value. This often leads to significant errors.

6. Can a lock be acquired on a class?
Yes, a lock can be acquired on a class. This lock is acquired on the class's Class object..

7. What's new with the stop(), suspend() and resume() methods in JDK 1.2?
The stop(), suspend() and resume() methods have been deprecated in JDK 1.2.

8. Is null a keyword?
The null value is not a keyword.

9. What is the preferred size of a component?
The preferred size of a component is the minimum component size that will allow the component to display normally.

10. What method is used to specify a container's layout?
The setLayout() method is used to specify a container's layout.

11. Which containers use a FlowLayout as their default layout?
The Panel and Applet classes use the FlowLayout as their default layout.

12. What state does a thread enter when it terminates its processing?
When a thread terminates its processing, it enters the dead state.

13. What is the Collections API?
The Collections API is a set of classes and interfaces that support operations on collections of objects.

14. Which characters may be used as the second character of an identifier,
but not as the first character of an identifier?
The digits 0 through 9 may not be used as the first character of an identifier but they may be used after the first character of an identifier.

15. What is the List interface?
The List interface provides support for ordered collections of objects.

16. How does Java handle integer overflows and underflows?
It uses those low order bytes of the result that can fit into the size of the type allowed by the operation.

17. What is the Vector class?
The Vector class provides the capability to implement a growable array of objects

18. What modifiers may be used with an inner class that is a member of an outer class?
A (non-local) inner class may be declared as public, protected, private, static, final, or abstract.

19. What is an Iterator interface?
The Iterator interface is used to step through the elements of a Collection.

20. What is the difference between the >> and >>> operators?
The >> operator carries the sign bit when shifting right. The >>> zero-fills bits that have been shifted out.

21. Which method of the Component class is used to set the position and
size of a component?
setBounds()

22. How many bits are used to represent Unicode, ASCII, UTF-16, and UTF-8 characters?
Unicode requires 16 bits and ASCII require 7 bits. Although the ASCII character set uses only 7 bits, it is usually represented as 8 bits. UTF-8 represents characters using 8, 16, and 18 bit patterns. UTF-16 uses 16-bit and larger bit patterns.

23What is the difference between yielding and sleeping?
When a task invokes its yield() method, it returns to the ready state. When a task invokes its sleep() method, it returns to the waiting state.

24. Which java.util classes and interfaces support event handling?
The EventObject class and the EventListener interface support event processing.

25. Is sizeof a keyword?
The sizeof operator is not a keyword.

26. What are wrapped classes?
Wrapped classes are classes that allow primitive types to be accessed as objects.

27. Does garbage collection guarantee that a program will not run out of memory?
Garbage collection does not guarantee that a program will not run out of memory. It is possible for programs to use up memory resources faster than they are garbage collected. It is also possible for programs to create objects that are not subject to garbage collection

28. What restrictions are placed on the location of a package statement
within a source code file?
A package statement must appear as the first line in a source code file (excluding blank lines and comments).

29. Can an object's finalize() method be invoked while it is reachable?

30. What is the immediate superclass of the Applet class?
Panel

31. What is the difference between preemptive scheduling and time slicing?
Under preemptive scheduling, the highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence. Under time slicing, a task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and
other factors.

Static RAM: No refreshing, 6 to 8 MOS transistors are required to form one memory cell, Information stored as voltage level in a flip flop.
Dynamic RAM: Refreshed periodically, 3 to 4 transistors are required to form one memory cell, Information is stored as a charge in the gate to substrate capacitance.

What is an interrupt?
Interrupt is a signal send by external device to the processor so as to request the processor to perform a particular work.

What are the different types of interrupts?
Maskable and Non-maskable interrupts.

What is cache memory?
Cache memory is a small high-speed memory. It is used for temporary storage of data & information between the main memory and the CPU (center processing unit). The cache memory is only in RAM.
