IntegerInstantiation


IntegerInstantiation
egerInstantiation">IntegerInstantiation
		Since: PMD 3.5
		In JDK 1.5, calling new Integer() causes memory allocation.  Integer.valueOf() is more memory friendly.
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                      
//PrimaryPrefix
 /AllocationExpression
  [not (ArrayDimsAndInits)
   and (ClassOrInterfaceType/@Image='Integer'
    or ClassOrInterfaceType/@Image='java.lang.Integer')]
                  
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Foo {
 private Integer i = new Integer(0); // change to Integer i = Integer.valueOf(0);
}
