Java Sneppets

In JavaSE 7 or later you can replace the type arguments eg., 'String, Integer' with empty set of type arguments "<>". As long as compiler can determine or can do type inference, the type arguments.

This pair of  angle brackets "<>" is called as diamond operator.

For example you can create an instance of IGenericEntry with the following statement:

IGenericEntry entry1 = new GenericEntryImpl<>("Nithi", 30);

instead of

IGenericEntry entry1 = new GenericEntryImpl("Nithi", 30);
