public interface Control {

public void Do();

}

public class WinForm implements Control {

private String name ;

private Frame frame = new Frame("");

public WinForm(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

frame.Do() ;

}

public void AddControl(Control control){

frame.AddControl(control) ;

}

}

import java.util.ArrayList;

import java.util.List;

public class Frame implements Control {

private String name;

private List<Control> subObjs = new ArrayList<>();

public Frame(String name){

this.name = name ;

}

public void Do(){

if ( !name.equals("") ){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

for (Control obj : subObjs){

obj.Do();

}

}

public void AddControl(Control control){

subObjs.add(control) ;

}

}

public class Button implements Control {

private String name ;

public Button(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

}

public class CheckBox implements Control{

private String name ;

public CheckBox(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

}

public class Lable implements Control{

private String content ;

public Lable(String content){

this.content = content ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.content) ) ;

}

}

public class LinkLable implements Control {

private String content ;

public LinkLable(String content){

this.content = content ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.content) ) ;

}

}

public class PasswordBox implements Control{

private String name ;

public PasswordBox(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

}

public class Picture implements Control{

private String name ;

public Picture(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

}

public class StringUtil {

public static String outputString(String typeName, String content){

return String.format("print %s(%s)", typeName, content) ;

}

}

public class TextBox implements Control {

private String name ;

public TextBox(String name){

this.name = name ;

}

public void Do(){

System.out.println( StringUtil.outputString( this.getClass().getName(), this.name) ) ;

}

}

public class windowns {

public static void main(String[] args){

WinForm winFrm = new WinForm("WINDOW窗口") ;

winFrm.AddControl(new Picture("LOGO图片")) ;

winFrm.AddControl(new Button("登录")) ;

winFrm.AddControl(new Button("注册")) ;

Frame frame = new Frame("FRAME1") ;

frame.AddControl(new Lable("用户名"));

frame.AddControl(new TextBox("文本框"));

frame.AddControl(new Lable("密码"));

frame.AddControl(new PasswordBox("密码框"));

frame.AddControl(new CheckBox("复选框"));

frame.AddControl(new TextBox("记住用户名"));

frame.AddControl(new LinkLable("忘记密码")) ;

winFrm.AddControl(frame) ;

winFrm.Do();

}

}

输出

print WinForm(WINDOW窗口)

print Picture(LOGO图片)

print Button(登录)

print Button(注册)

print Frame(FRAME1)

print Lable(用户名)

print TextBox(文本框)

print Lable(密码)

print PasswordBox(密码框)
