Sorting Array:

Sorting Array:

import java.util.Arrays;

 public class MainClass { 
   public static void main(String args[]) throws Exception {
             int array[] = { 2, 5, -2, 6, -3, 8, 0, -7, -9, 4 }; 
                Arrays.sort(array);
                   printArray("Sorted array", array); 
                     int index = Arrays.binarySearch(array, 2);
                      System.out.println("Found 2 @ " + index); 
                    }
           private static void printArray(String message, int array[]) {
               System.out.println(message + ": [length: " + array.length + "]");
                   for (int i = 0; i < array.length; i++) {
                      if(i != 0){ System.out.print(", ");
                   }
 System.out.print(array[i]); 
 } 
 System.out.println(); }
 } 

Result:

The above code sample will produce the following result.
Sorted array: [length: 10] -9, -7, -3, -2, 0, 2, 4, 5, 6, 8 Found 2 @ 5
