sort array of strings in java code example

Example 1: sort array java

Here’s the java program to sort an array using Arrays.sort() method.

import java.util.Arrays;
public class JavaArraySortMethod
{
   public static void main(String[] args)
   {
      String[] strGiven = {"Great Barrier Reef", "Paris", "borabora", "Florence","tokyo", "Cusco"};
      Arrays.sort(strGiven);
      System.out.println("Output(case sensitive) : " + Arrays.toString(strGiven));
   }
}

Example 2: How to sort a string array in java

// how to sort string array in java without using sort method
import java.util.Arrays;
public class SortStringArray
{
   public static void main(String[] args)
   {
      String[] strPlaces = {"Great Barrier Reef", "Paris", "BoraBora", "Florence","Tokyo", "Cusco"};
      int size = strPlaces.length;
      for(int a = 0; a < size - 1; a++)
      {
         for(int b = a + 1; b < strPlaces.length; b++)
         {
            if(strPlaces[a].compareTo(strPlaces[b]) > 0)
            {
               String temp = strPlaces[a];
               strPlaces[a] = strPlaces[b];
               strPlaces[b] = temp;
            }
         }
      }
      System.out.println(Arrays.toString(strPlaces));
   }
}

{
   public static void main(String[] args)
   {

Example 4: how to sort an array

import java.util.Scanner;
public class JavaExample 
{
    public static void main(String[] args) 
    {
    	int count, temp;
    	
    	//User inputs the array size
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter number of elements you want in the array: ");
        count = scan.nextInt();
    
        int num[] = new int[count];
        System.out.println("Enter array elements:");
        for (int i = 0; i < count; i++) 
        {
            num[i] = scan.nextInt();
        }
        scan.close();
        for (int i = 0; i < count; i++) 
        {
            for (int j = i + 1; j < count; j++) { 
                if (num[i] > num[j]) 
                {
                    temp = num[i];
                    num[i] = num[j];
                    num[j] = temp;
                }
            }
        }
        System.out.print("Array Elements in Ascending Order: ");
        for (int i = 0; i < count - 1; i++) 
        {
            System.out.print(num[i] + ", ");
        }
        System.out.print(num[count - 1]);
    }
}

Example 5: string sorting in java

public class ArrayReturn3 {
 
    public static String[] sortNames(String[] userNames) {
        String temp;
        for (int i = 0; i < userNames.length; i++) {
            for (int j = i + 1; j < userNames.length; j++) {
                if (userNames[i].compareTo(userNames[j]) > 0) {
                    temp = userNames[i];
                    userNames[i] = userNames[j];
                    userNames[j] = temp;
                }
            }
        }
        return userNames;
    }
 
    public static void main(String[] args) {
        String[] names = {"Ram", "Mohan", "Sohan", "Rita", "Anita", "Nita", "Shyam", "Mukund"};
        System.out.println("Names before sort");
        for (String n : names) {
            System.out.print(" " + n);
        }
        String[] sortedNames = sortNames(names);
        System.out.println("\nNames after sort (Sent name)");
        for (String n : names) {
            System.out.print(" " + n);
        }
        System.out.println("\nNames after sort (Received name)");
        for (String n : sortedNames) {
            System.out.print(" " + n);
        }
    }
}
