      // initializing char array
      char arr[] = new char[] {'a','b','c','d','e','f'};

      System.out.println("Actual values: ");
      for (char value : arr) {
         System.out.println("Value = " + value);
      }

      // using fill for placing z from index 2 to 4
      Arrays.fill(arr, 2, 4, 'z');

      // let us print the values
      System.out.println("New values after using fill() method: ");
      for (char value : arr) {
         System.out.println("Value = " + value);
