public Destination dest(String s) {
class PDestination
implements Destination {
private String label;
private PDestination(String whereTo) {
label = whereTo;
}
public String readLabel() { return label; }
}
return new PDestination(s);
}



我是這樣認為的
return new PDestination(s);昰對PDestination(string s)進行實例化,對一個類實例的同時會執行這個類,也就是在這時調用public String readLabel() { return label; }的

请问:
//: c13:TrackEvent.java
// Show events as they happen.

} ///:~
上面这段代码中,init()代码段中的(JTextField) t是什么时候和怎么被赋值的,谢谢
