Usage

From source file:Main.java

public static void main(String[] args) {

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

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

    // using fill for placing 18 from index 2 to 4
    Arrays.fill(arr, 2, 4, 18);// ww  w .  ja  v  a2  s  .  c  o  m

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

From source file:Main.java

public static void main(String[] args) {

    // initializing unsorted byte array
    byte bArr[] = { 10, 12, 7, 35 };

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

    // sorting array
    Arrays.sort(bArr);/* ww w. ja  va2 s .  c  om*/

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

From source file:Main.java

    // copying array arr1 to arr2 with newlength as 5
    int[] arr2 = Arrays.copyOf(arr1, 5);
    arr2[3] = 4;//w  w w. j a  va2 s .c  o m
    arr2[4] = 5;

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

    // initializing unsorted int array
    int iArr[] = { 12, 1, 119, 16, 4 };

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

    // sorting array
    Arrays.sort(iArr);/*from w ww.java  2  s.  c o m*/
