用java写一个鸡兔同笼

import java.util.Scanner;

public class ChickenRabbitCage {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入总数：");
int total = scanner.nextInt();
System.out.println("请输入总腿数：");
int legs = scanner.nextInt();

int rabbits = (legs - total * 2) / 2;
int chickens = total - rabbits;

if (rabbits < 0 || chickens < 0 || legs % 2 != 0) {
System.out.println("无法计算鸡兔数量，请重新输入！");
} else {
System.out.println("鸡的数量为：" + chickens);
System.out.println("兔的数量为：" + rabbits);
}
}
}
