Usage

From source file:Main.java

public static void main(String[] args) {

    int[] arr1 = new int[] { 5, 60, 75 };

    System.out.println(Arrays.toString(arr1));

    // copying array arr1 to arr2 with range from index 2 to 6
    int[] arr2 = Arrays.copyOfRange(arr1, 2, 6);

    System.out.println(Arrays.toString(arr2));
}

From source file:Main.java

public static void main(String[] args) {
    long[] arr1 = new long[] { 5, 60, 75 };

    System.out.println(Arrays.toString(arr1));

    // copying array arr1 to arr2 with range of index from 2 to 5
    long[] arr2 = Arrays.copyOfRange(arr1, 2, 5);

    System.out.println(Arrays.toString(arr2));
}

From source file:Main.java

public static void main(String[] args) {

    short[] arr1 = new short[] { 15, 10, 45 };

    System.out.println(Arrays.toString(arr1));

    // copying array arr1 to arr2 with range of index from 1 to 3
    Object arr2 = Arrays.copyOfRange(arr1, 1, 3);

    // cast arr2 as short in order to be printable
    short[] arr3 = (short[]) arr2;

    System.out.println(Arrays.toString(arr3));
}

From source file:Main.java

public static void main(String[] args) {

    float[] arr1 = new float[] { 10f, 30f, 50f };

    byte[] arr2 = Arrays.copyOfRange(arr1, 1, 7);

    System.out.println(Arrays.toString(arr2));
}
