A wrapper class is a class which contains the primitive data types (int, char, short, byte, etc). in other words, wrapper classes provide a way to use primitive data types (int, char, short, byte, etc) as objects. these wrapper classes come under java. util package.. why we need wrapper class. wrapper class will convert primitive data types into objects. the objects are necessary if we wish to. Everything in java is an object, except primitives. primitives are int, short, long, boolean, etc. since they are not objects, they cannot return as objects, and collection of objects. to support this, java provides wrapper classes to move primitives to objects. some of the wrapper classes are integer, long, boolean, etc.
