This is an example of how to sort arrays. We are using anint array in the example, but the same API applies to any type of arrays e.g.byte[],char[],double[],float[],long[],short[]. Sorting an int array implies that you should:

• Create anint array with elements.
• Invokesort(int[] a) API method ofArrays. It sorts an array in ascending order based on quicksort algorithm.
• We can fully sort an array by usingsort(array) method ofArrays or we can partially sort an array by usingsort(array, startIndex, endIndex) API method of Arrays wherestartIndex is inclusive andendIndex is exclusive. We can print the array’s elements before and after sorting in order to check the elements’ sorting.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;import java.util.Arrays; public class SortArrayExample {   public static void main(String[] args) {     /*Please note that the same API applies to any type of arrays e.g. byte[], char[], double[], float[], long[], short[]    */    // Create int array    int intArray[] = {1,4,3,5,2};     System.out.print("Array prior sorting :");    for(int i=0; i< intArray.length ; i++)System.out.print("  "  + intArray[i]);     /*     Arrays.sort() method sorts an array in ascending order based on quicksort     algorithm. We can fully sort an array by using Arrays.sort(array) operation      or we can partially sort an array by using Arrays.sort(array, startIndex, endIndex)      operation where startIndex is inclusive and endIndex is exclusive    */    Arrays.sort(intArray);     System.out.print("nArray after full sort :");    for(int i=0; i< intArray.length ; i++)System.out.print("  "  + intArray[i]);  }}

Output:

Array prior sorting :  1  4  3  5  2Array after full sort :  1  2  3  4  5
