Discussion Forum : Flow Control - Finding the output (Q.No. 8)
8.
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 ) ;
}
}
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.

code can be write as:
do
{
while(I>1)S.O.P("I is :"+I);
}
while(I<1);
As 1 statement ends with the encounter of; which is present at the end of the print statement that's why there is no need of braces after "do" . and both conditions are false that's why no output.
do
{
while(I>1)S.O.P("I is :"+I);
}
while(I<1);

In the definition of the block, if we don, t specify statement using block ({}), only the first statement consider. Here condition file so no output produced.
