Usage

From source file:Main.java

public static void main(String[] args) {

    // initializing unsorted float array
    float fArr[] = { 13.2f, 1.2f, 0.7f, 1.2f, 4.5f };

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

    // sorting array
    Arrays.sort(fArr);

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

From source file:Main.java

public static void main(String[] args) {
    Integer[] points = new Integer[5];
    points[0] = 4;/* www  . j a v  a2s  .co  m*/
    points[1] = 3;
    points[2] = 0;
    points[3] = 4;
    points[4] = 4;

    Arrays.sort(points);
    System.out.println(Arrays.toString(points));

    Arrays.sort(points, Collections.reverseOrder());
    System.out.println(Arrays.toString(points));
}

From source file:Main.java

public static void main(String[] args) {

    char[] firstString = str.toLowerCase().toCharArray();
    char[] secondString = str1.toLowerCase().toCharArray();

    Arrays.sort(firstString);
    Arrays.sort(secondString);/*www.j av a  2  s .  c  o m*/

    if (Arrays.equals(firstString, secondString) == true) {
        System.out.println("same");
    } else {
        System.out.println("different");
    }
}
