Usage

From source file:Main.java

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

    byte[] byteArr = new byte[10];
    byte byteFillValue = (byte) 0xFF;
    Arrays.fill(byteArr, byteFillValue);
}

From source file:Main.java

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

    double[] doubleArr = new double[10];
    double doubleFillValue = -1;
    Arrays.fill(doubleArr, doubleFillValue);
}

From source file:Main.java

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

    boolean[] booleanArr = new boolean[10];
    boolean booleanFillValue = false;
    Arrays.fill(booleanArr, booleanFillValue);
}

From source file:Main.java

public static void main(String[] args) {

    boolean arr[] = new boolean[] { true, true, false };

    System.out.println(Arrays.toString(arr));

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

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

From source file:MainClass.java

public static void main(String[] a) {
    byte array[] = new byte[10];
    //    Arrays.fill(array, 4); // illegal
    for (int i : array) {
        System.out.println(i);//from   w  w w  .  ja va2s . c  om
    }
    Arrays.fill(array, (byte) 4); // Okay
    for (int i : array) {
        System.out.println(i);
    }
}

From source file:Main.java

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

  boolean[] booleanArr = new boolean[10];
  boolean booleanFillValue = false;
  Arrays.fill(booleanArr, booleanFillValue);
}

From source file:Main.java

public static void main(String[] args) {

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

    System.out.println(Arrays.toString(arr));

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

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

From source file:Main.java

public static void main(String[] args) {

    // initializing long array
    long arr[] = new long[] { 1, 6, 4, 49, 227 };

    System.out.println(Arrays.toString(arr));

    // using fill for placing 12
    Arrays.fill(arr, 12);

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

From source file:Main.java

public static void main(String[] args) {

    // initializing short array
    short arr[] = new short[] { 1, 2, 3, 4, 13 };

    System.out.println(Arrays.toString(arr));

    // using fill for placing 23
    Arrays.fill(arr, (short) 23);

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

From source file:Main.java

public static void main(String[] args) {

    // initializing float array
    float arr[] = new float[] { 1f, 2f, 3f, 4f, 5f };

    System.out.println(Arrays.toString(arr));

    // using fill for placing 12
    Arrays.fill(arr, 12f);

    System.out.println(Arrays.toString(arr));
