# Java Examples - Array sort and search

## Problem Description:

How to sort an array and search an element inside it?

## Solution:

Following example shows how to use sort () and binarySearch () method to accomplish the task. The user defined method printArray () is used to display the output:

    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
