Java Program to illustrate Autoboxing and Unboxing

Autoboxing and Unboxing in Java

With 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 the 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 myStack=new Stack();
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);
}
}
