菜鸟日记之利用java往注册表里读和写值

java 代码

import java.util.prefs.*;
import java.util.*;
//查看注册表的路径为HKEY_LOCAL_MACHINE\Software\JavaSoft\prefs\javaplayer
public class CatchUrlFormRegedit {
        static String keys = "haha";
        String values = "d:/test.bat";
     //把相应的值储存到变量中去
        public void writeValue() {
     // HKEY_LOCAL_MACHINE\Software\JavaSoft\prefs下写入注册表值.
            Preferences pre = Preferences.systemRoot().node("/javaplayer");

                pre.put(keys, values);
        }
        public static void main(String[] args) {
            CatchUrlFormRegedit reg = new CatchUrlFormRegedit();
         //   reg.writeValue();
            reg.readValue(keys);
}

        private void readValue(String keys) {
            // TODO Auto-generated method stub
            Preferences pre = Preferences.systemRoot().node("/javaplayer");
            String batUrl = pre.get("haha","unknow");
            System.out.println("VALUE为："+batUrl);
        }
}
