What will be the output of the program?
public class Test 
{
    public static void main(String [] args) 
    {
        int I = 1;
        do while ( I < 1 )
        System.out.print("I is " + I);
        while ( I > 1 ) ;
    }
}
I is 1
I is 1 I is 1
No output is produced.
Compilation error
Answer: Option
Explanation:

There are two different looping constructs in this problem. The first is a do-while loop and the second is a while loop, nested inside the do-while. The body of the do-while is only a single statement-brackets are not needed. You are assured that the while expression will be evaluated at least once, followed by an evaluation of the do-while expression. Both expressions are false and no output is produced.

Answer should be option D. Compilation error due to unreachable code.

Is do-while syntax correct? guess not.

do while(); semicolon is required.
