Converting a string to uppcase

Question:

How do you convert a whole string to the upper case values?

Answer:

Using the String toUpperCase() method.

Code:

public class UpperCase {
 
   public static void main(String[] args) {
 
      String str = "abcdef ghijkl mnopqr stuvwxyz";
 
      String up = str.toUpperCase();
 
      System.out.println("Original string: " + str);
      System.out.println("Upper case:      " + up);
   }
}

Output:

$ java UpperCase 
Original string: abcdef ghijkl mnopqr stuvwxyz
Upper case:      ABCDEF GHIJKL MNOPQR STUVWXYZ
