Sorts the specified array of objects into ascending order, according to the Comparable natural ordering of its elements.

Usage

From source file:SearchTest.java

public static void main(String args[]) throws Exception {
    int array[] = { 2, 5, -2, 6, -3, 8, 0, -7, -9, 4 };

    // Ensure array sorted
    Arrays.sort(array);
    printArray("Sorted array", array);

    // Search for element in array
    int index = Arrays.binarySearch(array, 2);
    System.out.println("Found 2 at " + index);

    // Search for element not in array
    index = Arrays.binarySearch(array, 1);
    System.out.println("Didn't find 1 at " + index);

    // Insert//from w w  w .  j  a  v  a 2 s. com
    int newIndex = -index - 1;
    array = insertElement(array, 1, newIndex);
    printArray("With 1 added", array);

}

From source file:Main.java

public static void main(String[] args) {
    float[] f1 = new float[] { 3.1f, 2.1f, 5.1f, 4.1f, 1.1f };

    for (float f : f1) {
        System.out.print(" " + f);
    }/*from   ww w  .j  a  va  2s. c o  m*/
    Arrays.sort(f1);

    for (float f : f1) {
        System.out.print(" " + f);
    }

    float[] f2 = new float[] { 5.1f, 2.1f, 3.1f, 1.1f, 4.1f };
    Arrays.sort(f2, 1, 4);

    for (float f : f2) {
