这个问题令人困惑，但这就是我想要做的：

public class Main
{
    MyClass instance = new MyClass();
    Thread secondThread = new Thread(instance);

    public static void main()
    {
         secondThread.start();
         //here i want to call foo(), but be processed by secondThread thread(not the Main thread)
    }
}


public class MyClass implements Runnable
{
    @Override
    public void run()
    {

    }

    public void foo()
    {
        System.out.println("foo");
    }
}

如果我使用“instance.foo();” 它将由主线程处理。
