What is the use of Wrapper class

You can create an object of Wrapper class using a String or a primitive data type

Integer num = new Integer (4); or
Integer num = new Integer (-4?);

You can get a primitive data type from a Wrapper using the corresponding value function

int primNum = num.intValue() ;
