Java Program to Sort an Array in Ascending Order

Predefined Array Sorting
Program :-

import java.util.Arrays; 
  
public class SortExample 
{ 
    public static void main(String[] args) 
    { 
        // Our arr contains 8 elements 
        int[] arr = {13, 7, 6, 45, 21, 9, 101, 102}; 
  
        Arrays.sort(arr); 
  
        System.out.printf("sorted  : %s", 
                          Arrays.toString(arr)); 
    } 
} 

User -defined Array Sorting
Program :-

import java.util.Scanner;
public class SortFun 
{
    public static void main(String[] args) throws Exception
    {
     int count, temp;
     
    
        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]);
    }
}
