说出下列E类中【代码1】~【代码3】的输出结果。class Fish {int weight = 1;}class Lake {Fish fish;void setFish(Fish s){fish = s;}void foodFish(int m) {fish.weight=fish.weight+m;}}public class E {public static void main(String args[]) {FishredFish = new Fish();System.out.println(redFish.weight);//【代码1】Lake lake = new Lake();lake.setFish(redFish);lake.foodFish(120);System.out.println(redFish.weight);//【代码2】System.out.println(lake.fish.weight);//【代码3】}}
