//按下按钮,触发一些事件
Frame frame = new Frame();
Button button = new Button("Twq");
//因为addActionListener需要一个ActionListener,所以,我们需要构造一个ActionListener
//构造原则:是接口就实现其方法,是父类就继承
MyActionListener myActionListener = new MyActionListener();
button.addActionListener(myActionListener);
frame.add(button);
frame.setSize(300,200);
frame.setVisible(true);

TextField textField = new TextField();
MyMoniter2 moniter2 = new MyMoniter2();
//每次通过回车触发监视器
textField.addActionListener(moniter2);
// //在前台实现输入的内容为*,但是后台获取可以正常获取输入的数据
// textField.setEchoChar(*);
add(textField);
pack();
setVisible(true);
class MyMoniter2 implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
Object source = e.getSource();
TextField tf = (TextField)source;
System.out.println(tf.getText());//获取文本框的输入的数据
tf.setText("");//每次回车之后将文本框内容清空
运行结果图
在前台输入框中不显示输入数据,但是在后台可以正常获取文本框中的数据

public MyMoniter3(TextField num1,TextField num2,TextField num3) {
this.num1 = num1;
this.num2 = num2;
this.num3 = num3;
@Override
public void actionPerformed(ActionEvent e) {
//1.获得加数和被加数
int i1 = Integer.parseInt(num1.getText());
int i2 = Integer.parseInt(num2.getText());
//2.将两个数相加之后的值放入第三个文本框
num3.setText(""+(i1+i2));
//3.清除前两个框
num1.setText("");
num2.setText("");
运行结果图如下
代码优化(转换为面向对像)

Calculator calculator;
public MyMoniter3(Calculator calculator) {
this.calculator = calculator;
@Override
public void actionPerformed(ActionEvent e) {
//1.获得加数和被加数
int i1 = Integer.parseInt(calculator.num1.getText());
int i2 = Integer.parseInt(calculator.num2.getText());
//2.将两个数相加之后的值放入第三个文本框
calculator.num3.setText(""+(i1+i2));

Label label = new Label("+");
MyMoniter3 m = new MyMoniter3();
button.addActionListener(m);
pack();
add(num1);
add(label);
add(num2);
add(button);
add(num3);
setLayout(new FlowLayout());
setVisible(true);
addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
//监听器类,内部类最大的好处就是可以畅通无阻的访问外部内的属性和方法
class MyMoniter3 implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
//1.获得加数和被加数
int i1 = Integer.parseInt(num1.getText());
int i2 = Integer.parseInt(num2.getText());
//2.将两个数相加之后的值放入第三个文本框
num3.setText(""+(i1+i2));
//3.清除前两个框
num1.setText("");
num2.setText("");

addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
//重写画笔方法
@Override
public void paint(Graphics g) {
//设置画笔颜色
g.setColor(Color.red);
//画一个空心圆
g.drawOval(100,100,200,200);

Iterator iterator = points.iterator();
while(iterator.hasNext()){
//将当前获取到的数组中的点转换为一个点类
Point point = (Point)iterator.next();
//设置鼠标点击点的颜色
g.setColor(Color.CYAN);
//让当前画笔获得鼠标点击的位置
g.fillOval(point.x,point.y,10,10);
//将获取到的鼠标的点存储到数组里
public void addPaint(Point point){
points.add(point);
//若采用实现MouseListener接口的话,就必须要重写其接口内的所有方法
//所以可以采用适配器模式去重写自己需要的方法,
class MouseListenered extends MouseAdapter {
//鼠标有按下,弹起,按住不放
@Override
public void mousePressed(MouseEvent e) {
//在窗口上获取当前鼠标的位置
