DefaultLabelNotLastInSwitchStmt


DefaultLabelNotLastInSwitchStmt
By convention, the default label should be the last label in a switch statement.
       
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//SwitchStatement
 [not(SwitchLabel[position() = last()][@Default='true'])]
 [SwitchLabel[@Default='true']]

                 
  
		    
		    
	    
	    
        
        
        Example:
            
                    
   
public class Foo {
 void bar(int a) {
  switch (a) {
   case 1:  // do something
      break;
   default:  // the default case should be last, by convention
      break;
   case 2:
      break;
  }
 }
}
