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);
}
