Explain Diamond Operator in Java.

<> denotes the diamond operator. Purpose of the diamond operator is to simplify instantiation of generic classes.

For example, see the below.

List<Integer> myList = new ArrayList<Integer>(); 
//with the diamond operator we can write as below easily.

List<Integer> myList = new ArrayList<>(); 

The Diamond Operator reduces some of Java's verbosity surrounding generics by having the compiler infer parameter types for constructors of generic classes.
