Example 2: 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 3: sorting array in descending order java

// A sample Java program to sort a subarray 
// in descending order using Arrays.sort(). 
import java.util.Arrays; 
import java.util.Collections; 
  
public class SortExample 
{ 
    public static void main(String[] args) 
    { 
        // Note that we have Integer here instead of 
        // int[] as Collections.reverseOrder doesn't 
        // work for primitive types. 
        Integer[] arr = {13, 7, 6, 45, 21, 9, 2, 100}; 
  
        // Sorts arr[] in descending order 
        Arrays.sort(arr, Collections.reverseOrder()); 
  
        System.out.printf("Modified arr[] : %s", 
                          Arrays.toString(arr)); 
    } 
}
