Developing String Functions in Java - Part II

Welcome to the II installment of our series on Java programming for MSBTE Diploma students focusing on various aspects of Java programming. In this part, we will explore different functions of the String class in Java and learn how to implement them in your programs.

String Class Overview

The String class in Java is a fundamental class used for working with strings. It provides a wide range of methods to manipulate and perform operations on strings. As a diploma engineering student learning Java, understanding these functions is crucial for your programming journey.

Implementing String Functions

Let's look at some common string functions and how to implement them in Java:

1. Length of a String

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

Output:

Length of the string: 20

2. Concatenation

public class StringFunctionsDemo {
    public static void main(String[] args) {
        String str1 = "Hello, ";
        String str2 = "MSBTE Diploma!";
        String result = str1.concat(str2);
        System.out.println("Concatenated string: " + result);
    }
}

Output:

Concatenated string: Hello, MSBTE Diploma!

3. Substring

public class StringFunctionsDemo {
    public static void main(String[] args) {
        String str = "Hello, MSBTE Diploma!";
        String subStr = str.substring(7, 15);
        System.out.println("Substring: " + subStr);
    }
}

Output:

Substring: MSBTE Di

Conclusion

Understanding and implementing the various functions of the String class is essential for any diploma engineering student learning Java. In this article, we've covered a few fundamental string functions, but there are many more to explore. As you continue your Java journey, practice and experimentation will be key to mastering these concepts.
