package com.imooc;

public class HelloWorld {
private String name="imooc";
int age=20;
public class Inner{
String name="爱慕课";
public void show(){
System.out.println("外部类中的name："+HelloWorld.this.name);
System.out.println("内部类中的name:"+name);
System.out.println("外部类中的age："+age);
}
public static void main(String[] args) {
HelloWorld o = new HelloWorld();
Inner inn = o.new Inner();
inn.show();
}
}
}
提示错误
The method main cannot be declared static; static methods can only be declared in a static or top level type

你的main方法放错地方了，应该是放到外部类中的，而你放的是内部类中。内部类不是static修饰肯定会报错啊 改成这样就可以了： public class HelloWorld { private String name = "imooc"; int age = 20; public class Inner { String name = "爱慕课"; public void show() { System.out.println("外部类中的name：" + HelloWorld.this.name); System.out.println("内部类中的name:" + name); System.out.println("外部类中的age：" + age); } } public static void main(String[] args) { HelloWorld o = new HelloWorld(); Inner inn = o.new Inner(); inn.show(); } }
