while(true)

[Phillipe Rodrigues]

I want to know the line no(1) execution. What the (1) check. What is the other way we can specify line no (1)

public class TGo implements Runnable{
public static void main(String argv[]){
        TGo tg = new TGo();
        Thread t = new Thread(tg);
        t.start();
        }
        public void run(){
                [B]while(true)[/B]..............(1)
{
                        Thread.currentThread().sleep(1000);
                        System.out.println("looping while");
                        }
        }
}

A while(true) loop is an infinite loop - the loop never terminates (at least, not until you stop the program).

How can I write the line(1) using the If condition?

[Nickolas Case]

Set a boolean method and test on that.

  private isTrue {
          if (a == b){
            return true;
          }
          else {
            return false;
          }
        }
 
        private whileLoop{
         while(isTrue){
          //do something
         }
}

You cannot, because if is not a looping construct like while.

You could do this trick with for, but I don't recommend it, because it's more unreadable than the version with while:

for (;;)  {  // Infinite loop
  // ...Do something...
}

while(true) means ?

is it saying while the run() is getting executed or what while(true) checks.when the while condition executes?

It just literally means that as long as true == true, the loop will continue. Since true is always equal to true, it means "loop forever."
