请解释一下这段Java代码是如何从用户输入中识别出最大数字的？

import java.util.Scanner;

public class MaxNumberFinder {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入数字序列，以空格分隔：");
        String input = scanner.nextLine();
        String[] numbers = input.split(" ");
        int max = Integer.MIN_VALUE;
        
        for (String number : numbers) {
            int currentNumber = Integer.parseInt(number);
            if (currentNumber > max) {
                max = currentNumber;
            }
        }
        
        System.out.println("最大的数字是：" + max);
    }
}
