Exercise – Infinite loop

Write one or two examples of an infinite loop.

Answer

Here is one possible infinite loop implementation:

while(true){
  System.out.println("try and stop me"); //prints indefinitely
}

The following is another one:

for (;;){
  System.out.println("try and stop me"); //prints indefinitely
}

And this one is an infinite loop, too:

for (int x=2; x > 0; x--){
  System.out.println(x++ + " "); //prints 2 indefinitely
}

In this code, the Boolean expression x > 0 is always evaluated to true because x is initialized to 2 and then incremented and decremented by 1 in each iteration.
