I am using this blog post to build upon these examples to demonstrate the utility of Java 7’s Objects.equals(Object, Object) method and will demonstrate the usefulness of Objects.hash(Object ...

The equals method is used to compare two objects for equality. It should follow four general rules: reflexivity, symmetry, transitivity, and consistency.

The only thing that’s not so nice is the need to explicitly scope Guava’s Objects class in the code to avoid a naming collision with Java SE 7’s Objects class.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only ...

Remember that when you create objects, the variables store references to the objects. So, when you compare objects using the equality testing operator (==), it actually compares the references and not ...
