利用java得到硬盘信息
import java.io.File;
/**

* jdk6.0下的磁盘使用情况例子

public class Diskfree {
public static void main(String[] args) {
File[] roots = File.listRoots();//获取磁盘分区列表
for (File file : roots) {
System.out.println(file.getPath()+"信息如下:");
System.out.println("空闲未使用 = " + file.getFreeSpace()/1024/1024/1024+"G");//空闲空间
System.out.println("已经使用 = " + file.getUsableSpace()/1024/1024/1024+"G");//可用空间
System.out.println("总容量 = " + file.getTotalSpace()/1024/1024/1024+"G");//总空间
System.out.println();
}
}
}
java如何获取远程计算机的系统信息,cpu使用情况,磁盘使用情况等等
1、在远程server里搭建一个http服务,并支持某种服务端语言(如.net或php之类)
2、用服务端语言获取到服务器的磁盘信息,把结果输出
3、在本地用JS写一段AJAX脚本,远程请求服务端写好的程序,得到结果,并展示给用户

function disk() {//硬盘序列号 信息
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_DiskDrive");
var e = new Enumerator (properties);
document.write("table border=1");
for (;!e.atEnd();e.moveNext ())
{
var p = e.item ();
document.write("tr");
document.write("td" + p.signature + "/td");
document.write("/tr");
}
document.write("/table");

在这上找的代码:
对于写过ASP或.net 的人来说,通过asp或.net 语言来获得客户端的硬件信息是很熟悉的.但如何通过javascript这种客户端脚本来获得客户端的信息呢?请看以下实例:

使用javascript方式获得客户端的信息主要的优点是,不需求服务器资源.不需求刷新网页.直接在客户端执行脚本获得显示.
在这上找到了硬盘序列号的参数:
\'获得硬盘序列号
Dim cmicWmi As New System.Management.ManagementObjectSearcher(\"SELECT * FROM Win32_DiskDrive\")
Dim Uint32 As UInt32
For Each cmicWmiObj As ManagementObject In cmicWmi.Get
Uint32 = cmicWmiObj(\"signature\")
Next
TextBox1.Text = Uint32.ToString
和在一块总算给提出来了,呵呵。
java中读取磁盘文件并显示所有学生信息的代码
你自己改动一下文件名字就好了。
import java.util.*;
import java.io.File;
import java.io.FileWriter;
import java.io.FileReader;
import java.io.BufferedWriter;
import java.io.BufferedReader;
import java.io.IOException;
public class Main_3{
public static void main(String args[]){
File file = new File("c:\\pldok.log");
BufferedReader reader = null;
try {
System.out.println("read in file by line!");
reader = new BufferedReader(new FileReader(file));
String tempString = null;
int line = 1;
while ((tempString = reader.readLine()) != null) {
System.out.println("line " + line + ": " + tempString);
line++;
}
reader.close();
}
catch (IOException e) {
e.printStackTrace();
}
finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e1) {
}
}
}
}
}
用java怎么遍历磁盘上的所有文件
首先,我们需要获取磁盘中所有的盘符路径:jdk6中一个方法搞定:
File [] roots = File.listRoots();
然后,通过每个路径来进行向下遍历,上代码(手敲,各种小错误别怪我,看思路就好):
import java.io.File;
/**
由于本人使用了junit,请自行添加main方法测试
*/
public class Test{
@org.junit.Test
public void testfiles(){
File [] roots = File.listRoots();
for(File f:roots){
System.out.println(f.getAbsolutePath());
}
listFiles(roots);
}
public void listFiles(File[] files){
if(files==null||files.length==0)return;
for(File f : files){
if(f.isDirectory()){
System.out.println(f.getAbsolutePath());
listFiles(f.listFiles());
}else{
System.out.println("\t|"+f.getName());
}
}
}
}
Java如何获得硬盘剩余空间?
java中可以使用file对象,获取当前电脑硬盘基本信息,示例如下:
import java.io.File;
public class DiskSpaceDetail {
public static void main(String[] args) {
File diskPartition = new File("C:");
long totalCapacity = diskPartition.getTotalSpace();
long freePartitionSpace = diskPartition.getFreeSpace();
long usablePatitionSpace = diskPartition.getUsableSpace();
System.out.println("**** Sizes in Mega Bytes ****\n");
System.out.println("Total C partition size : " + totalCapacity / (1024*1024) + " MB");
System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024) + " MB");
System.out.println("Free Space : " + freePartitionSpace / (1024 *1024) + " MB");
System.out.println("\n**** Sizes in Giga Bytes ****\n");
System.out.println("Total C partition size : " + totalCapacity / (1024*1024*1024) + " GB");
System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024*1024) + " GB");
System.out.println("Free Space : " + freePartitionSpace / (1024 *1024*1024) + " GB");
}
}
java中怎样获取某个磁盘名称
问了一下我远标出来的程序员哥们,她说,你看下对不对
swing下的包,javax.swing.filechooser.FileSystemView;可以获取:
FileSystemView fileSys=FileSystemView.getFileSystemView(); //获取当前系统文件类型
//获取系统的所有盘符或系统卷类型
for(File f:File.listRoots()){
System.out.println(fileSys.getSystemDisplayName(f));//获取系统卷标及名字
System.out.println(fileSys.getSystemTypeDescription(f));//获取系统卷的类型
System.out.println(f.getTotalSpace());//获取该卷大小(单位:字节)
System.out.println(f.getFreeSpace());//获取该卷可用大小(单位:字节)
}
