补全代码package step1; public class Client { public static void main(String[] args) { CucumberCrop cucumberCrop=new CucumberCrop("黄瓜实验田1"); CauliflowerCrop cauliflowerCrop = new CauliflowerCrop("花菜实验田2"); TomatoCrop tomatoCrop = new TomatoCrop("番茄实验田3"); CropGroup cropgroup = new CropGroup(); cropgroup.addCrop(cucumberCrop); cropgroup.addCrop(cauliflowerCrop); cropgroup.addCrop(tomatoCrop); CropVisitor visitor = new GrowthVisitors(); cropgroup.accept(visitor); /********** Begin *********/ /********** End *********/ } }

请补全代码如下：

package step1;

public class Client {
    public static void main(String[] args) {
        CucumberCrop cucumberCrop = new CucumberCrop("黄瓜实验田1");
        CauliflowerCrop cauliflowerCrop = new CauliflowerCrop("花菜实验田2");
        TomatoCrop tomatoCrop = new TomatoCrop("番茄实验田3");
        CropGroup cropgroup = new CropGroup();
        cropgroup.addCrop(cucumberCrop);
        cropgroup.addCrop(cauliflowerCrop);
        cropgroup.addCrop(tomatoCrop);
        CropVisitor visitor = new GrowthVisitors();
        cropgroup.accept(visitor);

        CropVisitor pestVisitor = new PestsVisitors();
        cropgroup.accept(pestVisitor);
    }
}
