Java Program to illustrate Autoboxing and Unboxing

The Autoboxing and Unboxing features, we can convert primitive data types to the wrapper class types automatically. The compiler generates a code implicitly to convert primitive type to the wrapper class type and vice-versa.

Program:

import java.util.Stack;
public class test
{
 public static void main(String args[])
{
 Stack<integer> myStack=new Stack<integer>();
 myStack.push(10);   // Autobox
 myStack.push.(20);  // Autobox
 int stackSum= myStack.pop()+ myStack.pop();  // Unboxing
System.out.println("The Top Element of the Stack is:"+ myStack.pop());
System.out.println("The next Top Element of the Stack is:"+ myStack.pop());
System.out.println("The Sum of two Element of the Stack is:"+ stackSum);
}
}
