ShortInstantiation


ShortInstantiation
rtInstantiation">ShortInstantiation
		Since: PMD 4.0
		In JDK 1.5, calling new Short() causes memory allocation. Short.valueOf() is more memory friendly.
          
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//PrimaryPrefix
/AllocationExpression
[not (ArrayDimsAndInits)
and (ClassOrInterfaceType/@Image='Short'
or ClassOrInterfaceType/@Image='java.lang.Short')]

          
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo {
private Short i = new Short(0); // change to Short i =
Short.valueOf(0);
}
