Explain the difference between Integer and int in java.The following are the differences:
- Integer is a wrapper class, where as int is a primitive data type.
- Integer can be used as an argument to a method which requires an object, where as int can be used as an argument to a method which requires an integer value, that can be used for arithmetic expression.
- The variable of int type is mutable, unless it is marked as final. Integer class contains one int value and are immutable.
