import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

      // initializing int array
      int arr[] = new int[] {1, 6, 3, 2, 9};

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

      // using fill for placing 18
      Arrays.fill(arr, 18);

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

Let us compile and run the above program, this will produce the following result −

Actual values:
Value = 1
Value = 6
Value = 3
