Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

public class Javaexcercise {
       public static void main(String[] args)
    {
        String str = "TECHSTUDY - The Complete Debugging Solution";
 
        // Convert the above string to all lowercase.
        String lowerStr = str.toLowerCase();
 
        // Display the two strings for comparison.
        System.out.println("Original String: " + str);
        System.out.println("String in lowercase: " + lowerStr);
    }
}

Result
