Wht is the meanig of wrapper class. Everyone use this class but why??

Answer 1

A Wrapper class is a class whose object contains a primitive data types. When we create an object to a wrapper class, it contains a field and in this field we can store a primitive data type. In other words, we can wrap a primitive value into a wrapper class object and perform some further operations on it.

Answer 2

There used to turn primitives types into objects.

Answer 3

sometimes we cant use primitive types when we need it because the parameter doesnt accept primitive types

for example you want to use an arraylist for your integer but ArrayList<int> will cause an error, because we need a class. this is where we'll need a wrapper class
ArrayList<Integer>
