Question
int i = 1, j = 10;
do
{
if(i > j)
{
break;
}
j--;
} while (++i < 5);
System.out.println("i = " + i + " and j = " + j);
What will be the output of the program?
int i = 1, j = 10;
do
{
if(i > j)
{
break;
}
j--;
} while (++i < 5);
System.out.println("i = " + i + " and j = " + j);

This loop is a do-while loop, which always executes the code block within the block at
least once, due to the testing condition being at the end of the loop, rather than at the
beginning. This particular loop is exited prematurely if ibecomes greater than j.
The order is, test i against j, if bigger, it breaks from the loop, decrements j by one, and
then tests the loop condition, where a pre-incremented by one i is tested for being lower
than 5. The test is at the end of the loop, so ican reach the value of 5 before it fails. So it
goes, start:
1, 10
2, 9
3, 8
4, 7
5, 6 loop condition fails.
