EmptyWhileStmt


EmptyWhileStmt
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.
       
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//WhileStatement/Statement[./Block[count(*) = 0]  or ./EmptyStatement]

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