Usage

From source file:Main.java

public static void main(String[] args) {

    byte[] arr1 = new byte[] { 5, 15, 25 };

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

    // copying array arr1 to arr2 with newlength as 5
    byte[] arr2 = Arrays.copyOf(arr1, 5);
    arr2[3] = 0;/*  www.ja v a 2  s.c o  m*/
    arr2[4] = 1;

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

From source file:Main.java

public static void main(String[] args) {
    int[] unsorted = { -3, 10, -4, 11, 5, 1, 2 };
    System.out.println(Arrays.toString(unsorted));
    int[] sorted = unsorted;
    Arrays.sort(sorted);//from   www  .jav  a  2 s  .  c o m
    System.out.println(Arrays.toString(sorted));
    int breakingPoint = Arrays.binarySearch(sorted, 5);
    for (int i = breakingPoint; i < sorted.length; i++) {
        System.out.println(sorted[i]);
    }
}

From source file:Main.java

public static void main(String[] args) {
    boolean[] arr1 = new boolean[] { true, false };

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

    // copying array arr1 to arr2 with newlength as 4
    boolean[] arr2 = Arrays.copyOf(arr1, 4);

    // printing the array arr2
    System.out.println(Arrays.toString(arr2));
}

From source file:Main.java

public static void main(String[] args) {

    char[] arr1 = new char[] { 'j', 'a', 'v' };

}

From source file:Main.java

public static void main(String[] args) {

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

    // copying array arr1 to arr2 with newlength as 5 as Object
    Object arr2 = Arrays.copyOf(arr1, 5);

    // 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) {

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

    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 };

    Arrays.fill(arr, 1, 3, 12f);/*from   w w w.  ja  va2  s .  c om*/

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