UseArrayListInsteadOfVector


UseArrayListInsteadOfVector
ArrayList is a much better Collection implementation than Vector.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//AllocationExpression
 /ClassOrInterfaceType[@Image='Vector' or @Image='java.util.Vector']

              
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public class SimpleTest extends TestCase {
 public void testX() {
  Collection c = new Vector();
  // This achieves the same with much better performance
  // Collection c = new ArrayList();
 }
}
