How to interrupt an Infinite Loop

Question

Though I know it\'ll be a bit silly to ask, still I want to inquire more about the technical perspective of it.

A simple example of an infinite loop:

pub         


        

Answer 1

We can achieve it using volatile variable, which we will change ouside Thread and stop the loop.

   for(;!cancelled;) /*or while(!cancelled)*/{
       System.out.println("Stackoverflow");
   }

This is better way to write Infinite Loop.

public class LoopInfinite{
      private static volatile boolean cancelled=false;
      public static void main(String[] args){
             for(;!cancelled;) { //or while(!cancelled)
                    System.out.println("Stackoverflow");
             }
      }
      public void cancel(){
        cancelled=true;
      }
}
