2.个人负责模块或任务说明

监听器的设置

3.自己的代码提交记录截图

//注册各个组件监听事件

backspace.addMouseListener(new OperationMouseListener());

CE.addMouseListener(new OperationMouseListener());

C.addMouseListener(new OperationMouseListener());

decimal.addMouseListener(new OperationMouseListener());

equal.addMouseListener(new OperationMouseListener());

neg.addMouseListener(new OperationMouseListener());

//注册四则运算鼠标监听

add.addMouseListener(new CalcMouseListener());

sub.addMouseListener(new CalcMouseListener());

mul.addMouseListener(new CalcMouseListener());

div.addMouseListener(new CalcMouseListener());

//注册数字监听事件

zero.addMouseListener(new NumberMouseListener());

one.addMouseListener(new NumberMouseListener());

two.addMouseListener(new NumberMouseListener());

three.addMouseListener(new NumberMouseListener());

four.addMouseListener(new NumberMouseListener());

five.addMouseListener(new NumberMouseListener());

six.addMouseListener(new NumberMouseListener());

seven.addMouseListener(new NumberMouseListener());

eight.addMouseListener(new NumberMouseListener());

nine.addMouseListener(new NumberMouseListener());

}

private class NumberMouseListener implements MouseListener{

public void mouseClicked(MouseEvent e) {

if(input.getText().trim().equals("0")){//如果文本框已经是0，结果还是0

input.setText(((JButton)e.getSource()).getText().trim());

}else{//否则的话，把0添加到后面，譬如文本框是1，结果就为10

input.setText(input.getText().concat(((JButton)e.getSource()).getText().trim()));

}

}

public void mouseEntered(MouseEvent e) {}

public void mouseExited(MouseEvent e) {}

public void mousePressed(MouseEvent e) {}

public void mouseReleased(MouseEvent e) {}

}

private class CalcMouseListener implements MouseListener{

//如果输入的是运算符号，保存第一个结果和运算符号

public void mouseClicked(MouseEvent e) {

num1 = input.getText().trim();

input.setText("");

operator = ((JButton)e.getSource()).getText().trim();

input.setText(num1+operator);

}

public void mouseEntered(MouseEvent e) {}

public void mouseExited(MouseEvent e) {}

public void mousePressed(MouseEvent e) {}

public void mouseReleased(MouseEvent e) {}

}

4、自己负责模块或任务详细说明

设置监听器与字符运算符的判定存取。

5.课程设计感想

通过课设，能初步掌握监听器的使用。

发现自己不能很熟练的写出代码，应加强代码学习。
