Java Example – Sort String Array

In this Java Example we will learn How To sort String array (Array of string values) in java, use Arrays.sort method. Array.sort is method is a static method and Sorts the specified array of objects into ascending order, according to the {Comparable natural ordering} of its elements.
One this to note here is, by default Arrays.sort method sorts the Strings in case sensitive manner. To sort an array of Strings irrespective of case, use Arrays.sort(String[] strArray, String.CASE_INSENSITIVE_ORDER) method instead.

/**
 * String array in java by codebind.com.
 */
import java.util.Arrays;

public class SortStringArray {

    public static void main(String args[]){

        //String array
        String[] strNames = new String[]{"Lina", "alina", "Tom", "Jack", "harry", "Ram"};

        //sort String array using sort method
        Arrays.sort(strNames);

        System.out.println("String array sorted (CASE SENSITIVE ORDER)");

        //print sorted elements
        for(int i=0; i < strNames.length; i++){
            System.out.println(strNames[i]);
        }

        
        //case insensitive sort
        Arrays.sort(strNames, String.CASE_INSENSITIVE_ORDER);

        System.out.println("String array sorted (CASE INSENSITIVE ORDER)");
        //print sorted elements again
        for(int i=0; i < strNames.length; i++){
            System.out.println(strNames[i]);
        }

    }
}

/*
Output :
String array sorted (CASE SENSITIVE ORDER)
Jack
Lina
Ram
Tom
alina
harry
String array sorted (CASE INSENSITIVE ORDER)
alina
harry
Jack
Lina
Ram
Tom
