Usage

From source file:Main.java

public static void main(String[] args) {
    char c = 'x';
    int length = 10;

    // creates char array with 10 elements
    char[] chars = new char[length];

    // fill each element of chars array with 'x'
    Arrays.fill(chars, c);

    // print out the repeated 'x'
    System.out.println(String.valueOf(chars));
}

From source file:Main.java

public static void main(String[] args) {

    // initializing double array
    double arr[] = new double[] { 1.2, 5.6, 3.4, 2.3, 6.7 };

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

    // using fill for placing 1.2
    Arrays.fill(arr, 1.2);

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

From source file:Main.java

public static void main(String[] args) {

    // initializing Object array
    Object arr[] = new Object[] { 1.5, 5.6, 4.5, 2.3, 6.7 };

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

    // using fill for placing 12.2
    Arrays.fill(arr, 12.2);

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

From source file:Main.java

public static void main(String[] args) {

    // initializing byte array
    byte arr[] = new byte[] { 1, 6, 3 };

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

    // using fill for placing 8
    // converting int to byte

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