java sort method code example

Example 1: sort array java

import java. util. Arrays;
Arrays. sort(array);

Example 2: 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 3: Arrays.sort() in java

// how to sort an array in java without using sort method
public class WithoutUsingSortMethod
{
   public static void main(String[] args) 
   {
      int temp;
      int[] arrNumbers = {14, 8, 5, 54, 41, 10, 1, 500};
      System.out.println("Before sort: ");
      for(int num : arrNumbers)
      {
         System.out.println(num);
      }
      for(int a = 0; a <= arrNumbers.length - 1; a++)
      {
         for(int b = 0; b <= arrNumbers.length - 2; b++)
         {
            if(arrNumbers[b] < arrNumbers[b + 1])
            {
               temp = arrNumbers[b];
               arrNumbers[b] = arrNumbers[b + 1];
               arrNumbers[b + 1] = temp;
            }
         }
      }
      System.out.println("---------------");
      System.out.println("After sort: ");
      for(int num : arrNumbers)  
      {
         System.out.println(num);
      }
   }
}

Example 4: Arrays.sort() in java

// how to sort an array of strings in descending
import java.util.Arrays;
import java.util.Collections;
public class SortStringAlphabeticalOrder 
{
   public static void main(String[] args) 
   {
      String[] strDesc = {"Bear","Fox","Deer","Cheetah","Anteater","Elephant"};
      System.out.println("Before sorting: ");
      for(String string : strDesc)
      {
         System.out.println(string);
      }
      // arrays.sort
      Arrays.sort(strDesc, Collections.reverseOrder());   
      System.out.println("-----------------------------------");
      System.out.println("Sorting string array in descending or reverse order: ");
      for(String string : strDesc)
      {
         System.out.println(string);
      }
   }
}

Example 5: java sort method

Arrays.sort();//this method is an inbuild function in java
//to sort the array

Example 6: java array sort by element

//sort array of array of integer by the second element;
int[][] array = new int[m][2];
//initialize array
Arrays.sort(array, (a,b)-> Integer.compare(a[1], b[1]));
