What is wraper class??
Wrappers classes are used to convert string data type into any other data type
Coz bydefault java take input as string and if you need int type values you can use Integer.parseInt to convert in values in integers
Wrapper classes allow primitive data types to be accessed
as objects. They are one per primitive type: Boolean, Byte,
Character, Double, Float, Integer, Long and Short. Wrapper
classes make the primitive type data to act as objects.
