java GUI 圖形化使用者介面 算術測試小軟體

第二次用 mvc架構寫GUI java程式，寫的好不熟練啊~~ 3天木有看java ，知識點都忘完了。

上代碼和照片

貼代碼：

Main.java

public class Main {    public static void main(String args[]){    Window window=new Window();    window.setBounds(100, 100, 500, 130);    window.setVisible(true);    }}

Window.java

import java.awt.*;import java.awt.event.*;import javax.swing.*;public class Window extends JFrame implements ActionListener{   //利用視窗做監視器     /** *  */private static final long serialVersionUID = 1L; Sum sum;                         // model     Number generateNumber=new Number();  //model     JTextField text1,text2,text3;      //view     JButton getProblem,checkAnswer;    //contrller     JLabel answer;                     //view     Window(){     init();     setVisible(true);     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     }void init(){sum=new Sum();text1=new JTextField(10);text2=new JTextField(10);text1.setEditable(false);text2.setEditable(false);text3=new JTextField(10);answer=new JLabel("你還沒回答呢！");getProblem=new JButton("擷取題目");getProblem.addActionListener(this);checkAnswer=new JButton("確認答案");checkAnswer.addActionListener(this);setLayout(new FlowLayout());add(getProblem);add(text1);add(new JLabel("+"));add(text2);add(new JLabel("="));add(text3);add(checkAnswer);add(answer);}public void actionPerformed(ActionEvent e){       if(e.getSource()==checkAnswer){            int a,b,c;         a=Integer.parseInt(text1.getText());         b=Integer.parseInt(text2.getText());         c=Integer.parseInt(text3.getText());         sum.set(a, b);         if(c==sum.answer()){              answer.setText("答對了");              text3.setText("");                       }         if(c!=sum.answer()){              answer.setText("答錯了");              text3.setText("");         }        }       if(e.getSource()==getProblem){         text1.setText(String.valueOf(generateNumber.getNumber()) );         text2.setText(String.valueOf(generateNumber.getNumber()) );         answer.setText("你還沒回答呢！");       }              }}

Number.java

public class Number {    private int a;public int getNumber(){a=(int)(Math.random()*100)+1;return a;}}

sum.java

public class Sum {    private int a,b,c;    public void set(int a,int b){    this.a=a;    this.b=b;    }public int answer(){c=a+b;return c;}}
