B. 高分懸賞用java JNI實現獲取硬碟序列號、CPU序列號的實例分 請給出jni調用代碼、相關文件及使用方法！！
你這還不如直接用C去實現,java去調不覺得蛋疼嗎
C. java如何獲取硬碟物理地址
有個笨方法：new File(""); 獲取當前文件的絕對路徑，然後用String類中的split方法截取即可。
D. 用Java怎麼獲取烏班圖伺服器的磁碟序列號
String HDserialnumber=getHdSerialInfo() ;public static String getHdSerialInfo() { String line = ""; String HdSerial = "";//定義變數 硬碟序列號 try { Process proces = Runtime.getRuntime().exec("cmd /c dir c:");//獲取命令行參數 BufferedReader buffreader = new BufferedReader( new InputStreamReader(proces.getInputStream())); while ((line = buffreader.readLine()) != null) { if (line.indexOf("卷的序列號是 ") != -1) { //讀取參數並獲取硬碟序列號 HdSerial = line.substring(line.indexOf("卷的序列號是 ") + "卷的序列號是 ".length(), line.length()); break; // System.out.println(HdSerial); } } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return HdSerial;//返回硬碟序列號 卷的序列 非物理}
E. 跪求在JAVA里如何獲得CPU的序列號，和硬碟的序列號。
利用Runtime call操作系統的命令，具體的命令取決於不同的操作系統，注意不要調用Runtime.getRuntime().exec(String)介面，要用Runtime.getRuntime().exec(String[])這個介面，不然復雜命令的執行會有問題。例子如下（拿cpu個數，其他類似）：
定義命令：
WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊
SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};
AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};
HPUXCmd = {"/bin/sh", "-c", "echo \"map\" | /usr/sbin/cstm | grep CPU | wc -l "};
LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};
然後判斷系統：
os = System.getProperty("os.name").toLowerCase();
根據不同的操作系統call不同的命令。

F. 我寫的一段java代碼，怎麼存儲到硬碟上的數字信號怎麼轉化成電信號工作原理是什麼
你寫的代碼存放在文件上，自然會寫進硬碟。java代碼被cpu執行，cpu調用操作系統代碼，操作系統發出本地硬體指令，驅動硬體工作。
G. java 如何獲得磁碟名稱
swing下的包，javax.swing.filechooser.FileSystemView;可以獲取：
FileSystemView fileSys=FileSystemView.getFileSystemView(); //獲取當前系統文件類型
//獲取系統的所有盤符或系統卷類型
for(File f:File.listRoots()){
System.out.println(fileSys.getSystemDisplayName(f));//獲取系統卷標及名字
System.out.println(fileSys.getSystemTypeDescription(f));//獲取系統卷的類型
System.out.println(f.getTotalSpace());//獲取該卷大小(單位：位元組)
System.out.println(f.getFreeSpace());//獲取該卷可用大小(單位：位元組)
}
H. java 怎麼獲取硬碟序列號
publicstaticvoidmain(String[]args){
StringHDserialnumber=getHdSerialInfo();
System.out.println(HDserialnumber);
}
(){
Stringline="";
StringHdSerial="";//定義變數硬碟序列號
try{
Processproces=Runtime.getRuntime().exec("cmd/cdirc:");//獲取命令行參數
BufferedReaderbuffreader=newBufferedReader(newInputStreamReader(proces.getInputStream()));
while((line=buffreader.readLine())!=null){
if(line.indexOf("卷的序列號是")!=-1){//讀取參數並獲取硬碟序列號
HdSerial=line.substring(line.indexOf("卷的序列號是")+"卷的序列號是".length(),line.length());
break;
}
}
}catch(IOExceptione){
e.printStackTrace();
}
returnHdSerial;//返回硬碟序列號卷的序列非物理
}
I. 怎樣用java 獲取 硬碟 cpu 序列號，可調用dll實現
首先，你要用VC++等寫一個實現此功能的DLL導出函數，然後用JNI調用。
獲取CPU ID的代碼：
CString strTmp;
unsigned long s1,s2;
__asm{
mov eax,01h
xor edx,edx
cpuid
mov s1,edx
mov s2,eax
}
strTmp.Format("%08X%08X",s1,s2);
J. java獲取CPU與硬碟的ID號或調用JNI獲取，急用！！！！
可以用SNMP協議,一般的操作系統都會實現SNMP協議,該協議可以取得你感興趣的計算機的數據,比如CPU,磁碟,內存,等等信息,一般用來做監控計算機信息的一種方式來用,可以去找找SNMP4J的jar及相關文檔
