小编Dah*_*aka的帖子

我已经完成了我在网上找到的所有东西,但似乎我错过了一些非常基本的东西,花了这么多时间来解决这个问题并没有让事情变得更容易,所以我会继续在这里寻求帮助,看看是否你可以找到我做错了什么.

这是代码:

jControl.h

#ifndef _JCONTROL_H
#define _JCONTROL_H

namespace view
{


class jControl
{

public:


HWND hwnd;
HWND hParent;
HBITMAP hbitmap;
std::string text;
HFONT hFont;
COLORREF textColor;
COLORREF backgroundColor;
RECT updateRegion;
bool isUpdateRegion;

public:


jControl (  );

jControl ( HWND parent, HINSTANCE hInstance, WORD bitmap );

~jControl (  );

virtual void show (  );

virtual void hide (  );

virtual void disable (  );

virtual void enable (  );

virtual std::string getText (  );

virtual void setText ( std::string txt ); …

我正在网上学习Java的线程,我是初学者,我在理解一些概念方面遇到了困难.谁能帮我？

问题:

public class Core {
    public static void main(String[] args) {
        Runnable r0,r1;//pointers to a thread method
        r0=new FirstIteration("Danial"); //init Runnable, and pass arg to thread 1
        SecondIteration si=new SecondIteration();
        si.setArg("Pedram");// pass arg to thread 2

        r1=si; //<~~~ What is Happening here??

        Thread t0,t1;
        t0=new Thread(r0);
        t1=new Thread(r1);
        t0.start();
        t1.start();
        System.out.print("Threads started with args, nothing more!\n");
    }
}

编辑:FirstIteration和SceondIteration的代码

class FirstIteration implements Runnable{
    public FirstIteration(String arg){
        //input arg for this class, but in fact input …
