从内部匿名类访问外部匿名类 [英] Access outer anonymous class from inner anonymous class
本文介绍了从内部匿名类访问外部匿名类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我只是好奇。有没有办法访问另一个匿名类中的匿名类中的父级？
I'm just curious. Is there a way to access parent in anonymous class that is inside another anonymous class?
我让这个例子创建一个 JTable 子类（匿名类）覆盖 changeSelection 并在里面创建另一个匿名类。
I make this example create a JTable subclass (anonymous class) override changeSelection and inside i create another anonymous class.
MCVE：
public class Test{
public static void main(String args []){
JTable table = new JTable(){
@Override
public void changeSelection(
final int row, final int column,
final boolean toggle, final boolean extend) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
super.changeSelection(row, column, toggle, extend);
//more code here
}
});
}
};
}//end main
}//end test
我如何引用 super.changeSelection（..）？
推荐答案
不幸的是，你必须给外部匿名类命名：
Unfortunately, you will have to give a name to the outer anonymous class:
public class Test{
public static void main(String args []){
class Foo extends JTable {
@Override
public void changeSelection(
final int row, final int column,
final boolean toggle, final boolean extend) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
Foo.super.changeSelection(row, column, toggle, extend);
//more code here
}
});
}
};
JTable table = new Foo();
}//end main
}//end test
