语法错误:No enclosing instance of type VolatleTest is accessible. Must qualify the allocation with an enclosing instance of type VolatleTest (e.g. x.new A() where x is an instance of VolatleTest).
例:
public static void main(String[] args) { Task1 t1 =new Task1();//这里实例化的时候会报错,需要用 static 关键字来修饰内部类 } class Task1 implements Runnable{ @Override public void run() { } }
解决: static class Task implements Runnable
