在电脑上怎么运行JAVA软件游戏?(不要在网上复制，看不懂的，方法简单点的)

Java程序执行需要有JRE的支持。JRE在

www.java.com

可以下载，也可以在Oracle官网上下载。然后安装完毕即可。下载时注意游戏要求的是5.0还是6.0，或者是7.0的环境。

www.java.com

/zh_CN/download/manual.jsp

选择win7 XP 脱机版下载即可

要在电脑端玩手机的java程序，需要安装三个软件，一个java开发库，简称叫jdk，一个java运行环境简称jre。这两个程序可以在sun java网装上下载，是免费的。那个网站地址我记不清了，你在网络上搜索能找到的。jre是用来在操作系统上建立虚拟机系统给java程序运行的，jdk是用来给手机模拟器提供运行环境的。jdk本身就自带了一些手机模拟器。如果要用索爱模拟器的话，还要装一个semc java me cldc sdk软件，这是一个带索爱系列手机模拟器的java程序资源开发套件，可以在索爱手机官方网站下载，也是免费的。不过，索爱的最新开发套件的手机模拟器好像不支持中文，在其中运行的程序中文字符会显示成黑方块。而且，很多手机程序在索爱手机上能运行，在索爱的模拟器上却不能运行。所以，你也可以去摩托罗拉手机的官方开发网下载安装Moto SDK521套件，这个也是免费的，而且在电脑端的模拟器完全支持中文。

经过我的个人尝试，在摩托罗拉虚拟机中能运行的手机程序，在索爱k750c手机上能直接运行。

既然有了这三个软件(运行环境，java开发套件，手机程序开发套件)，那么我建议你索性在sun java网站再下载安装一个Neat Beans IDE 5.0软件和Mobility插件，这样你就可以在电脑端自己开发手机应用程序和游戏了。开发的游戏，可以放到手机里运行。体验一下在自己的手机里运行自己开发的软件的乐趣吧。这两个软件也是免费的，而且支持中文。如果你英文很过关，长时间看英文也不头晕，那你可以下载NetBeans 5.5
