跪求这个java程序怎么写

Fish.java：

public abstract class Fish {

public abstract int swim()

}

FishTest.java：

public class TestFish {

private void print(Fish fish) {

System.out.println("鱼游过" + fish.swim() + "米")

}

public static void main(String[] args) {

TestFish testFish = new TestFish()

Fish fish = new Fish() {

@Override

public int swim() {

return 10

}

}

testFish.print(fish)

}

}

运行结果：

你的情况我理解的时你可能swim寄存器swim_scr配置有问题。

写flash之前时需要解锁flash写保护的（针对byte写）如果实现块写，更需要让块写程序运行在RAM中。

希望帮到。~

一写就写多了，不过包含的东西比较多，java的重要知识点里面也有

这个结构是简单的处理的，有兴趣的话你可以想象下写成一个小的文字游戏

public class D {

public static void main(String[] args){

Cat cat1 = new Cat("Tom" , 10)

Cat cat2 = new Cat("Sun" , 15 , "苹果树")

Dog dog1 = new Dog("lufy" , 5)

Dog dog2 = new Dog("nan" , 20 , "泳池")

cat1.start()

cat2.start()

dog1.start()

dog2.start()

}

}
