java温度自控代码 温度转换java代码

java获取cpu温度,跪求源代码。。。

研究了一下

目前成都创新互联已为上1000+的企业提供了网站建设、域名、虚拟空间、网站托管、企业网站设计、北海网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。

cpu温度的数值由主板驱动供给windows，目前的现状是许多PC兼容机不提供或没安装“专用的主板驱动”(比如大量的ghost集成装机)，连win都没法获知温度，更别提win之上的Java。

在专用主板驱动安装正常的win-java系统下可以：

import java.util.Scanner;

public class Test {

static public void main(String 土数[]) {

try {

final String cmd="wmic /namespace:\\\\root\\WMI path MSAcpi_ThermalZoneTemperature get CurrentTemperature";

Process p = Runtime.getRuntime().exec(cmd);

p.getOutputStream().close();//这句不写就不执行

Scanner sc=new Scanner(p.getInputStream());

sc.next();

float t=(sc.nextInt()-2732f)/10f;

sc.close();

System.out.println("当前CPU温度:"+t);

p.waitFor();

} catch (Exception e) {

e.printStackTrace();

}

}

}

==

当前CPU温度:41.0

linux下同样依赖“主板驱动”, 数据提供给/dev/sensor

求好人做个关于温度计的JAVA程序

取个叫pb.java的文件拷贝进去（pb类为main入口），直接运行

楼主，

不好意思我是学j2ee的,GUI不会，你看我以前的回答一个awt和swing都没有的，这是我们项目组一个牛人的代码,我在我的新系统中嵌入的，我实在无能为力，你觉的好就用不好我也没办法的，

楼主你可以等等看，应该还有牛人有解决方法

________________________________________-

30分给你程序了，你真是。。。

我以前别人要源码的我100分才给的，

我都没用过awt,swing,里面的函数我都看不懂怎么话流程，你既然java是玩GUI的，流程图肯定自己要学着画，不然你怎么提高，我j2ee开发文档的流程图也都自己画的，

你觉得我这个给的不好你就把问题关闭了吧

怎么用java实现将华氏度转换为摄氏度，并以华氏度和摄氏度为单位分别显示该温度要求从控制台录入温度信息

Scanner input = new Scanner(System.in);

double h = input.nextDouble();

double c = (h - 32) / 1.8;

System.out.println("华氏度:"+h+"℉");

System.out.println("摄氏度:"+c+"℃");
