MSBTE Diploma in diploma engineering often includes learning programming languages like Java. Java for diploma students covers fundamental concepts, including data types. In this article, we will explore the concept of wrapper classes in Java, which are essential for converting primitive data types into objects.

Code Implementation

Wrapper classes in Java provide a way to convert primitive data types into objects. Here's a simple Java program that demonstrates how to use wrapper classes for this purpose:

import java.util.*;

public class WrapperExample {
    public static void main(String[] args) {
        // Create a primitive int
        int primitiveInt = 42;

        // Convert primitive int to Integer object
        Integer integerObject = Integer.valueOf(primitiveInt);

        // Display the result
        System.out.println("Primitive int: " + primitiveInt);
        System.out.println("Integer object: " + integerObject);

Code Output

After running the above program, you will see the following output:

Primitive int: 42
Integer object: 42


Wrapper classes in Java are invaluable when working with MSBTE Diploma in diploma engineering or any other Java-related courses. They allow you to work with primitive data types as objects, providing additional functionality and flexibility in your programs. Understanding wrapper classes is essential for any Java developer.
