Write a program to convert all the characters in a string to Uppercase

This Java program converts a given String to uppercase using the toUpperCase() method and prints the resulting uppercase String.

The program defines a public class named "UpperCase" with a main method that takes no arguments. The main method declares a String variable str with the value "Tutor Joes Computer Education".
Then, the program uses the toUpperCase() method of the String class to convert str to uppercase and stores the result in the String variable lwr_str.
Finally, the program prints out the original String str and the resulting uppercase String lwr_str using the System.out.println method.

Source Code

public class UpperCase
{
	public static void main(String[] args)
	{
		String str = "Tutor Joes Computer Education";
		String lwr_str = str.toUpperCase();
		System.out.println("Given String : " + str);
		System.out.println("String in Uppercase : " + lwr_str);
	}
}

Output

Given String : Tutor Joes Computer Education
String in Uppercase : TUTOR JOES COMPUTER EDUCATION
