Java sort method in array 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: java sort int array

// an array of ints
int[] arr = {1, 2, 3, 4, 5, 6};

// an array of reverse sorted ints
int[] arrDesc = Arrays.stream(arr).boxed()
    .sorted(Collections.reverseOrder())
    .mapToInt(Integer::intValue)
    .toArray();

System.out.println(Arrays.toString(arrDesc)); // outputs [6, 5, 4, 3, 2, 1]
