Hi Folks

code:
---------------
public TestCont
{
public static void main(String args[])
{
outer:
for (int i=0; i<5; i++) {
for (int j=0; j<5; j++) {
System.out.println("Hello");
continue outer;
} // end of inner loop
System.out.println("outer"); // Never prints
}
System.out.println("Good-Bye");
}

Running this code produces
Hello
Hello
Hello
Hello
Hello
Good-Bye

My question is why it doesnot prints "Outer"

Because you'll never reach the end of the inner loop.

The continue in the loop stops the execution of current iteration and goes to the next iteration.
When the iteration starts, it checks for the condition in the loop and if follows the execution of the loop if the condition is satisfied. If the condition is false, it won't enter into the loop and can't execute that statement.

Hope this is clear....

Hi Gaurav,



Here it goes:
Inside inner loop:
prints Hello, continue outer-> go to outer loop, i(1)<5 = true
prints Hello, continue outer-> go to outer loop, i(2)<5 = true
prints Hello, continue outer-> go to outer loop, i(3)<5 = true
prints Hello, continue outer-> go to outer loop, i(4)<5 = true
prints Hello, continue outer-> go to outer loop, i(5)<5 = false (exit from outer loop)

Question: Is statement "System.out.println("outer");" encounter anytime?
Answer: Never!
But compiler can't complaint about unreachable code, because continue is
inside the inner loop. If you make that in the outer loop, it will complaint, because of the unreachability of line.


Regards,
cmbhatt
