Interview Questions

Most of the times compilers will do optimization to the code to speed up the program. For example in the below code,

int k = 15;
while( k == 15)

{
// Do something
}

compiler may think that value of 'k' is not getting changed in the program and replace it with 'while(true)', which will result in an infinite loop. In actual scenario, the value of 'k' may be getting updated from outside of the program.

Volatile keyword is used to tell compiler that the variable declared using 'volatile' may be used from outside the current scope, so that compiler won't apply any optimization. This matters only in case of multi-threaded applications.

In the above example if variable 'k' was declared using volatile, compiler will not optimize it. In shot, value of the volatile variables will be read from the memory location directly.

Personality plays a role in behavioral interviews. Employers want to see that you are well balanced person that knows how to handle themselves. These types of questions are designed to see how you handled situations that can be very personally stressful. Try to share examples that reflect positively on all parties involved. “Once I was blamed for not double checking marketing data, which drastically impacted one of our campaigns. Though I was not the staff member in charge of the data collection and analysis, I knew it would be unproductive to try to pass blame, so I simply asked what steps I could take to help resolve the problem. Afterward I spoke with the staff member in charge of checking data and let them know of the error so that both of us could ensure it would not be repeated.”

If he was unable to make his shift, I would find a replacement, and stay until the replacement came in.

You may be very good at coding,but if you questioning how on earth you could solve this problem.Then here is a solution. If you remember the good old days of our primary school then the solution is easy,"division is a matter of iterative subtraction".

public class TestEvenOdd {
public static void main(String arg[ ]){
int num=6;
int result=num;
while(result>=2){
result=result-2;
}
if(result==1){
System.out.println("The number is odd");
}else{
System.out.print("The number is even");
}
}
}

By using $_SERVER['REMOTE_ADDR'], $_['HTTP_REFERER'] etc.

 These are the essential items that are present each time an Android project is created:

- AndroidManifest.xml

- build.xml

- bin/

- src/

- res/

- assets/

Mainframe Testing is similar to client-server applications testing, but you have to know how to operate basic TSO and ISPF commands and menus, view mainframe files, look at and use SDSF or other output tool, log on CICS and transactions, use FTP or another transfer protocol, submit the batch job - it's for QA testing of mainframe applications.
