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..
Write a Java program to convert all characters in a string to uppercase
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);
}
}Result
