TIOBE - Java Coding Standard

Rule: Basic3

Synopsis:	Avoid empty 'while' statements
Language:	Java
Severity Level:	2
Category:	Basic

Description:

Empty While Statement finds all instances where a while statement does nothing. If it is a timing loop, then you should use Thread.sleep() for it; if it's a while loop that does a lot in the exit expression, rewrite it to make it clearer.

public class Foo {
 void bar(int a, int b) {
  while (a == b) {
   // empty!
  }
 }
}
