是否有在Java關鍵字,以允許含有實例的成員的顯式調用(或它的超類的)從嵌套類內?是否可以顯式訪問包含類的嵌套類的實例成員?
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!請添加'Subclass.super.doSomething()',我會接受你的答案。 – arootbeer 2012-04-05 19:11:25
......咦。我不知道你可以這樣做。 – 2012-04-05 19:15:54
