• write all the letters in upper case.
• If constant contains more than one word they should be separated by underscore (_).

Example

Live Demo

   public static final int MIN_VALUE = 22;
   public static final int MAX_VALUE = 222;
   public static void main(String args[]) {
      System.out.println("Value of the constant MIN_VALUE: "+MIN_VALUE);
      System.out.println("Value of the constant MAX_VALUE: "+MAX_VALUE);
   }
}

Output

Value of the constant MAX_VALUE: 222
