Question:

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

Answer:

Using the String toLowerCase() method.

Code:

public class LowerCase {
 
   public static void main(String[] args) {
 
      String str = "ABCDEF GHIJKL MNOPQR STUVWXYZ";
 
      String low = str.toLowerCase();
 
      System.out.println("Original string: " + str);
      System.out.println("Lower case:      " + low);
   }
}
