Week 03 作业

作业一:手写单例模式

作业二:使用组合模式编写程序,打印输出图1的窗口,窗口组件的树结构图2,打印输出示例图3

定义接口

public interface InterfaceComponent {
void print();
}

定义组件抽象类

public abstract class Component implements InterfaceComponent {
private String name;
private List<Component> componentList;
public Component(Sting name) {
this.name = name;
componentList = new ArrayList<>();
}
public void add(Component comp) {
componentList.add(comp);
}
public void remove(Component comp) {
componentList.remove(comp);
}
@override
public void print() {
System.out.println("print " + name);
for (Component comp : componentList) {
comp.print();
}
}
}

具体组件

public class WindowForm extends Component {
public WindowForm(String name) {
super(name);
}
}
public class Picture extends Component {
public Picture(String name) {
super(name);
}
}
public class Button extends Component {
public Button(String name) {
super(name);
}
}
public class CheckBox extends Component {
public CheckBox(String name) {
super(name);
}
}
public class Frame extends Component {
public Frame(String name) {
super(name);
}
}
public class Label extends Component {
public Label(String name) {
super(name);
}
}
public class LinkLabel extends Component {
public LinkLabel(String name) {
super(name);
}
}
public class PasswordBox extends Component {
public PasswordBox(String name) {
super(name);
}
}
public class TextBox extends Component {
public TextBox(String name) {
super(name);
}
}

入口函数

public static void main(String[] args) {
Component windowFormComp = new WindowForm("WINDOW窗口");
windowFormComp.add(new Picture("LOGO图片"));
windowFormComp.add(new Button("登录"));
windowFormComp.add(new Button("注册"));
Component frameComp = new Frame("FRAME1");
frameComp.add(new Label("用户名"));
frameComp.add(new TextBox("文本框"));
frameComp.add(new Label("密码"));
frameComp.add(new PasswordBox("密码框"));
frameComp.add(new CheckBox("复选框"));
frameComp.add(new TextBox("记住用户名"));
frameComp.add(new LinkLabel("忘记密码"));
windowFormComp.add(frameComp);
windowFormComp.print();
}
