      // initializing float array
      float arr[] = new float[] {1f, 5f, 3f, 2f, 9f};

      // let us print the values
      System.out.println("Actual values: ");
      for (float value : arr) {
         System.out.println("Value = " + value);
      }

      // using fill for placing 12 from index 1 to 3
      Arrays.fill(arr, 1, 3, 12f);

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