是否有在Java关键字,以允许含有实例的成员的显式调用(或它的超类的)从嵌套类内?是否可以显式访问包含类的嵌套类的实例成员?
情景
public class Superclass {
public void doSomething() {
// do something that's of interest to the superclass
}
}
public class Subclass extends Superclass {
@Override
public void doSomething() {
// do something that's of interest to the subclass
// possibly call super.doSomething()
}
private class NestedClass {
private void doSomething() {
// do something that's of interest to the nested class
// calling doSomething() here without an explicit scope
// specifier results in a stack overflow
}
private void doSomethingElse() {
if (somethingOfInterestToTheSubclassIsNotImportant) {
// just invoke the superclass's doSomething() method
} else {
// invoke the subclass's doSomething() method
}
}
}
}
完美!请添加'Subclass.super.doSomething()',我会接受你的答案。 – arootbeer 2012-04-05 19:11:25
......咦。我不知道你可以这样做。 – 2012-04-05 19:15:54
