LongInstantiation


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

    
  
		    
		    
	    
	    
        
        
        Example:
            
                    

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