Write a Java program to convert all characters in a string to uppercase

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 uppercase.
        String upper_str = str.toUpperCase();
 
        // Display the two strings for comparison.
        System.out.println("Original String: " + str);
        System.out.println("String in uppercase: " + upper_str);
    }
}
