Give the output of following code and mention how many times the loop will execute?


int i;
for( i=5; i>=1; i--)
{
    if(i%2 == 1)
        continue;
    System.out.print(i+" ");
}

Output of the above code is:

4 2

Loop executes 5 times. The below table shows the dry run of the loop:

i	Output	Remark
5		1st Iteration — As i % 2 gives 1 so condition is true and continue statement is executed. Nothing is printed in this iteration.
4	4	2nd Iteration — i % 2 is 0 so condition is false. Print statement prints 4 (current value of i) in this iteration.
3	4	3rd Iteration — i % 2 is 1 so continue statement is executed and nothing is printed in this iteration.
2	4 2	4th Iteration — i % 2 is 0. Print statement prints 2 (current value of i) in this iteration.
1	4 2	5th Iteration — i % 2 is 1 so continue statement is executed and nothing is printed in this iteration.
0	4 2	As condition of loop (i >= 1) becomes false so loops exits and 6th iteration does not happen.

x = 10; y = 20;
do
{
    x++;
    y++;
} while (x<=20);
System.out.println(x * y );
