类与对象，求各位大神看一下哪里错了

[孤独的菜菜]

显示找不到main方法，百度解决，说保存一下在运行。可save键 点不了 package tedu.cn; import java.util.Scanner; public class Test { String name; String color; int weight; public void eat(String color,String name,int weight){ System.out.println("猫吃掉了老鼠"); } public void run(String name,String color,int weight) { System.out.println("老鼠跑掉了"); } } class Cat extends Test{ } class Mouse extends Test{ public static void main(String[] args) { Cat c = new Cat(); c.name="大橘"; c.color="橙色"; Scanner sc = new Scanner(System.in); System.out.println("请输入猫的体重"); int a =sc.nextInt(); c.weight=a; System.out.println(); Mouse m = new Mouse(); m.name="xx"; m.color="黑色"; for(int i=0;i<0;i++) { System.out.println("请输入老鼠的体重"); int b =sc.nextInt(); m.weight=b; if(a<5*b) { a+=1/3*b; }else { System.out.println("老鼠被猫吃掉了"); } if(a>5*b) { }else { System.out.println("老鼠跑掉了，猫饿死了"); } } } }

试试：

package tedu.cn;

import java.util.Scanner;

public class Test {
    String name;
    String color;
    int weight;

    public void eat(String color, String name, int weight) {
        System.out.println("猫吃掉了老鼠");
    }

    public void run(String name, String color, int weight) {
        System.out.println("老鼠跑掉了");
    }

}

class Cat extends Test {
}

class Mouse extends Test {

    public static void main(String[] args) {
        Cat c = new Cat();
        c.name = "大橘";
        c.color = "橙色";
        Scanner sc = new Scanner(System.in);
        System.out.println("请输入猫的体重");
        int a = sc.nextInt();
        c.weight = a;
        System.out.println();
        Mouse m = new Mouse();
        m.name = "xx";
        m.color = "黑色";

        for (int i = 0; i < 0; i++) {
            System.out.println("请输入老鼠的体重");
            int b = sc.nextInt();
            m.weight = b;
            if (a < 5 * b) {
                a += 1 / 3 * b;
            } else {
                System.out.println("老鼠被猫吃掉了");

            }
            if (a > 5 * b) {
            } else {
                System.out.println("老鼠跑掉了，猫饿死了");
            }
        }
    }
}

为什么会导致这种错误呢 ？

[孤独的菜菜]

你写的和我的没区别呀

[冲上云霄 、]

你下面那个for循环是干嘛的，i=0 后面 i<0这样写有啥意义？

[孤独的菜菜]

是写错了 本来是想重复生成新老鼠直到每次吃老鼠的猫体重增长到老鼠体重的5倍后跳出循环
