how to sort in java code example

Example 1: sort array java

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

Example 2: Arrays.sort() in java

// java program to sort strings in an alphabetical order
import java.util.Arrays;
public class SortStringAlphabeticalOrder
{
   public static void main(String[] args)
   {
      String[] strAsc = {"Bear","Fox","Deer","Cheetah","Anteater","Elephant"};
      System.out.println("Before sorting: ");
      for(String string : strAsc)
      {
         System.out.println(string);
      }
      // arrays.sort
      Arrays.sort(strAsc);
      System.out.println("-----------------------------------");
      System.out.println("After sorting: ");
      for(String str : strAsc)
      {
         System.out.println(str);
      }
   }
}

Example 3: 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 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: Arrays.sort() in java

// java sort arraylist
import java.util.ArrayList;
import java.util.Collections;
public class JavaSortArraylist 
{
   public static void main(String[] args) 
   {
      ArrayList<String> al = new ArrayList<String>();
      al.add("Bear"); 
      al.add("Fox"); 
      al.add("Deer"); 
      al.add("Cheetah"); 
      al.add("Anteater");
      al.add("Elephant");
      System.out.println("Before sorting ArrayList: " + al);
      Collections.sort(al); 
      System.out.println("After sorting ArrayList in Ascending order: " + al);
   }
}

Example 6: java sort method

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