  import java.util.Arrays;

public class Main{
  public static void main(String args[]) {
    int array[] = new int[10];
    for (int i = 0; i < 10; i++){
      array[i] = -3 * i;
    }
    System.out.print("Original contents: ");
    System.out.println(Arrays.toString(array));
    // fill and display
    Arrays.fill(array, 2, 6, -1);
    System.out.print("After fill(): ");
    System.out.println(Arrays.toString(array));
  }
}

The output:


Original contents: [0, -3, -6, -9, -12, -15, -18, -21, -24, -27]
After fill(): [0, -3, -1, -1, -1, -1, -18, -21, -24, -27]


import java.util.Arrays;

public class Main {
  public static void main(String[] argv) throws Exception {

  }
}


import java.util.Arrays;

    boolean booleanFillValue = true;

    Arrays.fill(booleanArr, startIndex, endIndex, booleanFillValue);

    System.out.println(Arrays.toString(booleanArr));
  }

The output:


[true, true, true, true, false, false, false, false, false, false]
