}追问

哥哎，你把它弄出来就是百度的资源了，老师查得到的

追答

你们老师还能搜到这里来？你尝试搜索下，看搜到这个几率有多大？

追问

好吧，能不能给我发一份说明文件，就是大概说说各步骤算法的作用什么的，发到Q1753932647里，除了这里的80分再给你50分，好不？

追答

就是计算器的哦，功能挺简单的，我这里发不了外部邮件，晚点我注释下，你很容易看懂得
public void mouseClicked(MouseEvent e) {
//如果按了数字但是文本框为0，说明没有数字输入，此时用按得键得数字代替0
if(input.getText().trim().equals("0")){
input.setText(((JButton)e.getSource()).getText().trim());
}else{
//否则，把数字添加到文本框的后面，譬如原来是12，按3，结果文本框就是123
input.setText(input.getText().concat(((JButton)e.getSource()).getText().trim()));
}
}

-
public void mouseClicked(MouseEvent e) {
if(e.getSource() == backspace){//退格删除一个字符
String inputText = input.getText();
if(inputText.length() > 0){//文本框有字符才删除
input.setText(inputText.substring(0, inputText.length() - 1));
}
}else if(e.getSource() == C){//C清空所有
input.setText("0");
num1 = "";
}else if(e.getSource() == CE){//CE，重新把文本框职置为0
input.setText("0");
}else if(e.getSource() == decimal){//如果是小数点，如果文本框已经有了譬如123.4,那么没有反应，如果是123,文本框置为123.
String text = input.getText().trim();

if(text.indexOf(".") == -1){
input.setText(text.concat("."));
}
}else if(e.getSource() == equal){//相等的话，开始运算
if(!operator.trim().equals("")){
if(!input.getText().trim().equals("")){
double result = 0D;
if(operator.equals("+")){//加法 result = Double.parseDouble(num1) + Double.parseDouble(input.getText().trim());
}else if(operator.equals("-")){//减法 result = Double.parseDouble(num1) - Double.parseDouble(input.getText().trim());
}else if(operator.equals("*")){//乘法 result = Double.parseDouble(num1) * Double.parseDouble(input.getText().trim());
}else if(operator.equals("/")){
result = Double.parseDouble(num1) / Double.parseDouble(input.getText().trim());
}
//格式化输出结果，保留2位小数
input.setText(new DecimalFormat("#.00").format(result));
}
}

追问

能再详细点吗、、、、

追答

其他的那些都很简单的了，都是最基本的java语法阿
