When we need to store primitive datatypes as objects, we use
wrapper classes.MEans in utility classes all the utility
classes stores Objects.So when we need to store a primitive
datatype.We make an object of theat primitive data and store it.

which encapsulates the primitive int data type and
represents in terms of object.
