Q6. Which of the following statements is true?

An exception can be thrown by throw keyword explicitly.

An exception can be thrown by throws keyword explicitly.

Q7. What happens when the following class is compiled and run.

public class test

{

public static void main(String args[]) 

{

int x = 0, y = 1, z;

if(x) 

z = 0;

else

z = 1;

if(y) 

 z = 2;

else

z = 3;

System.out.println(z); 

}

}

The program prints 1

The program prints 2

The program prints 3

The program does not compile because of problems in the if statement.

Q8. Which all lines are part of the output when the following code is compiled and run.

public class test {

public static void main(String args[]) {

  for(int i = 0; i < 3; i++) {

for(int j = 3; j >= 0; j--) {

    if(i == j) continue;

    System.out.println(i + " " + j);

}

    }

 }

}

 

a. 0 0 

b. 0 1 

c. 0 2 

d. 0 3 

e. 1 0 

f. 1 1 

g. 1 2 

h. 1 3 

i. 2 0 

j. 2 1 

k. 2 2 

l. 2 3 

a, b, c, d, e, i, j, k, l

b, c, d, e, g, h, i, j, l

b, c, e, j, k, l, f, h, i

c, d, e, f, g, h, i

Q9. What is the result of compiling and running this program?

public class test 

{

     public static void main(String args[])

     {

      int i, j;

      int k = 0;

      j = 2;

      k = j = i = 1;

      System.out.println(k);

 }

}

 

The program does not compile as k is being read without being initialized.

The program does not compile because of the statement k = j = i = 1;

The program compiles and runs printing 1.

The program compiles and runs printing 2.
