Develop a program for implementation of different functions of String Class. Part-1 in Java

Java programming is an essential skill for MSBTE Diploma students studying diploma engineering. Understanding the basics of Java and the String class is crucial for building robust applications. In this tutorial, we will explore some fundamental String operations in Java to help diploma engineering students kickstart their programming journey.

String Class Overview

The String class in Java is a part of the java.lang package and provides a rich set of methods to work with strings. It is widely used in Java applications for tasks like string manipulation, concatenation, searching, and more. Let's dive into some essential String functions.

String Length

To find the length of a string, you can use the length() method:

public class StringFunctions {
    public static void main(String[] args) {
        String text = "Hello, MSBTE Diploma!";
        int length = text.length();
        System.out.println("Length of the string: " + length);


Length of the string: 20


You can concatenate strings using the concat() method or the + operator:

public class StringFunctions {
    public static void main(String[] args) {
        String str1 = "Hello";
        String str2 = "MSBTE Diploma!";
        // Using concat method
        String result1 = str1.concat(" " + str2);
        // Using + operator
        String result2 = str1 + " " + str2;
        System.out.println("Using concat method: " + result1);
        System.out.println("Using + operator: " + result2);


Using concat method: Hello MSBTE Diploma!
Using + operator: Hello MSBTE Diploma!


In this Part 1 of our Java for MSBTE Diploma students series, we've covered some basic String operations. Understanding these fundamentals is essential for building more advanced programs in Java.
