Compare two objects with a check for null

Question

Is there a method in the JDK that compares two objects for equality, accounting for nulls? Something like this:

public static boolean equals(Object o1, Obje         


        

Answer 1

Whenever I come across a need and think "this is so common Java must have it" but find it doesn't, I check the Jakarta Commons project. It almost always has it. A quick search of the commons-lang API (which has the most basic of common utilities) shows an equals() method that provides what you want.
