java - 另一个类的内部类的实例化

Question

我有以下设置，我认为它可以工作，但在我的 IDE (Android Studio) 中出现错误:

// MyClass1.java
public class MyClass1{
    public MyClass1(){}
    public class MyNestedClass1{}
}

// MyClass2.java
public class MyClass2{
    public static MyClass1 MY_CLASS1 = new MyClass1();
    public MyClass2(){
        new MY_CLASS1.MyNestedClass1(); //Error
    }
}

具体的IDE错误是:

cannot resolve symbol MyNestedClass1

Answer 1

符号是

MY_CLASS1.new MyNestedClass1(); //No Error

语法是

<Expression that resolves to a reference of the enclosing class>.new [Name of nested inner class](..)
