Sorts the specified array of objects according to the order induced by the specified comparator.

Usage

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = { 1, 2, 3 };

    Arrays.sort(numbers, (i1, i2) -> {
        return (i2 - i1);
    });/*from  w  w w  .  ja va 2  s  .  c o m*/

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

From source file:Main.java

public static void main(String args[]) {

    String[] myArray = new String[] { "A", "B", "b" };
    Arrays.sort(myArray, Collator.getInstance());

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

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = new Integer[] { 2, 7, 3, 9, 5, 4, 6, 8, 1 };
    Arrays.sort(numbers, Integer::compareTo);
    Stream.of(numbers).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = { 1, 2, 3 };

    // watch return types, it is implied, no return keyword is necessary
    Arrays.sort(numbers, (i1, i2) -> i2 - i1);

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

From source file:Main.java

public static void main(String[] argv) {
    String[] rawStrings = { "B", "java2s.com", "b", "A", "a", "c", "C" };
    System.out.println(Arrays.toString(rawStrings));
    Arrays.sort(rawStrings, String.CASE_INSENSITIVE_ORDER);
    System.out.println(Arrays.toString(rawStrings));

}

From source file:Main.java

public static void main(String[] args) {
    String[] strings = { "Here", "are", "some", "sample", "strings", "to", "be", "sorted" };

        public int compare(String s1, String s2) {
            int c = s2.length() - s1.length();
            if (c == 0)
                c = s1.compareToIgnoreCase(s2);
            return c;
        }// w  ww  .  j  a v  a2  s.  c om
    });

    for (String s : strings)
        System.out.print(s + " ");
}

From source file:Main.java

    Arrays.sort(k1, new VersionNumberComparator());
    System.out.println(Arrays.asList(k1));
}

From source file:Main.java

public static void main(String[] args) {
    Integer[] arrayToSort = new Integer[] { new Integer(5), new Integer(89), new Integer(16), new Integer(2) };

    Arrays.sort(arrayToSort, Collections.reverseOrder());

    for (Integer i : arrayToSort) {
        System.out.println(i.intValue());
    }/*from w w w .j a v a  2 s.co  m*/
}

From source file:Main.java

public static void main(String[] args) {
    String[] array = { "Java", "C#", "Scala", "Basic", "C++", "Ruby", "Pyton", "Perl", "Haskell", "Jet" };

    Arrays.sort(array, (s1, s2) -> s1.charAt(0) - s2.charAt(0));

}

From source file:Main.java

public static void main(String[] args) {
