[問題] 查api 看到的code
在查 java.awt.Component時，看到下面的code
import java.awt.*;
import java.awt.event.*;
import java.io.Serializable;
class MyApp java.io.Serializable //想問的問題在這
{
BigObjectThatShouldNotBeSerializedWithAButton bigOne;
Button aButton = new Button();
static class MyActionListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
System.out.println("Hello There");
}
}
MyApp()
{
aButton.addActionListener(new MyActionListener());
}
}
class MyApp java.io.Serializable 這裡是少寫了 "implements" 嗎？
還是這是不用 implements這個key word的寫法？
