事件监听处理问题，求教

[qiuyuecd]

在编译时提示：(不知为何？？？？）
E:\MyPractice\myjava\scr\ExchangeFrameByAction.java:111: myclass.ButtonActionListener is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
class ButtonActionListener implements ActionListener{
^
E:\MyPractice\myjava\scr\ExchangeFrameByAction.java:125: cannot resolve symbol
symbol : class currentCommand
location: class myclass.ButtonActionListener
if ((currentCommand) equals( FrameOne.getWeatherBtn))



这段程序是这样写的（暂没用MVC，使用的是static var方式来处理）
//处理按钮监听事件
class ButtonActionListener implements ActionListener{

public JButton currentButton;
public String currentCommand;

public ButtonActionListener(JButton button){
currentButton = button;
}

public void actionPerformer(ActionEvent e){

currentCommand = e.getActionCommand();


if ((currentCommand) equals( FrameOne.getWeatherBtn))
ExchangeFrameByAction.frameTwo.show();

if ((currentCommand) equals (FrameTwo.getMessageBtn))
ExchangeFrameByAction.frameOne.show();

if ((currentCommand) equals (FrameOne.setWeatherBtn)){

FrameTwo.txtTwo.setText(FrameOne.txtOne.getText());
ExchangeFrameByAction.frameTwo.show();
}

if ((currentCommand) equals (FrameTwo.setMessageBtn)){
FrameOne.txtOne.setText(FrameTwo.txtTwo.getText());
ExchangeFrameByAction.frameOne.show();
}
}
}

actionPerformer
方法名写错了

哦，真粗心：）
提示下面是何原因：
E:\MyPractice\myjava\scr\ExchangeFrameByAction.java:123: cannot resolve symbol
symbol : class currentCommand
location: class myclass.ButtonActionListener
if ((currentCommand) equals( FrameOne.getWeatherBtn))
^

actionperform(event e)

不是事件监听处理问题，而是楼主太粗心的问题
if ((currentCommand) equals( FrameOne.getWeatherBtn))
应为
if (currentCommand.equals( FrameOne.getWeatherBtn))

可能是
if ((currentCommand).equals( FrameOne.getWeatherBtn))
或者
if ((currentCommand).equals( FrameOne.getWeatherBtn()))

public void actionPerformer(ActionEvent e){
写错了，呵呵。
