Trying to create a inner class that implement Runnable interface, got error: non static variable can not be referred from a static context

Question

我正在尝试提出一个实现 Runnable 接口的内部 class，在 main 方法中创建并启动一个新线程。

然而，IDE 一直告诉我

Error:

non static variable can not be referred from a static context

我不太清楚为什么会这样。

public class Test {
    
    class MyClass implements Runnable {
        @Override
        public void run(){
            System.out.println("hello");
        }
    }
    
    public static void main(String[] args) {
        Thread t = new Thread(new MyClass()); //error: non static variable can not be referred from a static context
        
    }
}

Answer 1

public static void main(String[] args) {
Test test = new Test(); 
    Thread t = new Thread(test.new MyClass());         
    t.start(); 
}

你需要这样使用它。
