成员内部类与局部内部类，代码举例说明

好的，下面是成员内部类和局部内部类的例子：

成员内部类：

public class OuterClass {
  private int x = 10;

  class InnerClass {
    public int getNum() {
      System.out.println("This is the getnum method of the inner class");
      return x;
    }
  }
}

public class Main {
  public static void main(String[] args) {
    OuterClass outer = new OuterClass();
    OuterClass.InnerClass inner = outer.new InnerClass();
    System.out.println(inner.getNum()); // 输出 10
  }
}

局部内部类：

public class OuterClass {
  private int x = 10;

  void doSomething() {
    class InnerClass {
      public void print() {
        System.out.println("This is the print method of the inner class");
      }
    }
    InnerClass inner = new InnerClass();
    inner.print(); // 输出 This is the print method of the inner class
  }
}

public class Main {
  public static void main(String[] args) {
    OuterClass outer = new OuterClass();
    outer.doSomething();
  }
}

希望能帮到你！
