java - 方法局部内部类

Question

public class Test {
    public static void main(String[] args) {

    }
}

class Outer {
    void aMethod() {
        class MethodLocalInner {
            void bMethod() {
                System.out.println("Inside method-local bMethod");
            }
        }
    }
}

谁能告诉我如何从 bMethod 打印消息？

Answer 1

您只能在 aMethod 中实例化 MethodLocalInner。也一样

void aMethod() {

    class MethodLocalInner {

            void bMethod() {

                    System.out.println("Inside method-local bMethod");
            }
    }

    MethodLocalInner foo = new MethodLocalInner(); // Default Constructor
    foo.bMethod();

}
