Converting to upper case in Java.
This method has two variants. The first variant converts all of the characters in this String to upper case using the rules of the given Locale. This is equivalent to calling toUpperCase(Locale.getDefault()).
The second variant takes a locale as an argument to be used while converting into upper case.
Example
import java.io.*;
public class Test {
public static void main(String args[]) {
String Str = new String("Welcome to Tutorialspoint.com");
System.out.print("Return Value :");
System.out.println(Str.toUpperCase());
}
}Output
Return Value :WELCOME TO TUTORIALSPOINT.COM
