Output the maximum value from the array using Java standard output

Java exercises on a certain site. A memo of the program that inputs the integer n as the standard input, then inputs n arbitrary numerical values and outputs the maximum value from them.

import java.util.Scanner;

public class Main{
   public static void main(String[] args){
      Scanner sc = new Scanner(System.in);
      //Enter the integer n
      int num = sc.nextInt();
      int max = 0;
      int[] array = new int[num];

      //Enter an arbitrary value n times
      for(int i = 0; i < num; i++){
         array[i] = sc.nextInt();
         if(max < array[i]){
            max = array[i];
