Membuat Program Ascending dan Descending pada Java

Ini semacam program untuk membuat ascending dan descending ketika kita menginputkan suatubilangan acak. Silahkan dicoba di rumah.


import java.io.*;
import java.util.Scanner;

public static int[] A = new int[10];

   System.out.print("Ada berapa bilangan yang akan dimasukkan bilangan :");
  a = s.nextInt();

for (int i = 0; i < 10; i++) {
try {

cmd = inputUser.readLine();
x = Integer.parseInt(cmd);
A[i] = x;
System.out.println("");
} catch (Exception e) {
System.out.println("angka yang anda masukan salah");
}
}
