JumbledIncrementer


JumbledIncrementer
Avoid jumbled loop incrementers - it's usually a mistake, and it's confusing even if it's what's intended.
     
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
     
//ForStatement
 [
  ForUpdate/StatementExpressionList/StatementExpression/PostfixExpression/PrimaryExpression/PrimaryPrefix/Name/@Image
  =
  ancestor::ForStatement/ForInit//VariableDeclaratorId/@Image
 ]
 
             
  
		    
		    
	    
	    
        
        
        Example:
            
                    
 
public class JumbledIncrementerRule1 {
  public void foo() {
   for (int i = 0; i < 10; i++) {
    for (int k = 0; k < 20; i++) {
     System.out.println("Hello");
    }
   }
  }
 }
