What will be the output ?

Question

int a=10,b=15;
While(a<b)
{
System.out.println(b);
a++;
b++;
}
System.out.println(a);

Answer 1

It'll result in an infinite loop because the condition of your while loop will never become false.
So it'll print the value of b incrementing each time.

Answer 2

Haha output never ends if the last line is System.out.println(a)

Else what ever you wrote it will throw a compiler erroe because ot doesn't recognise sysystem.out.println
