利用Java调用可执行命令
类别: JAVA教程 
package test;
/** * Add one sentence class summary here. * Add class description here. * * @author lxx * @version 1.0, 2004-11-16 */public class TestCmd { public TestCmd(){} /* public void main(String args[]){ try { Process process = Runtime.getRuntime().exec("cmd.exe /c start http://www.csdn.net"); //登录网站 Process process = Runtime.getRuntime().exec("cmd.exe /c start ping 10.144.98.100"); //调用Ping命令 }catch (Exception e) { e.printStackTrace(); } } } *///在项目下建立一个名为hello的文件夹 public static void main(String[] args) { System.out.println(System.getProperty("user.dir")); createFolder("hello"); }
private static void createFolder(String folderName) { String temp = System.getProperty("user.dir") + java.io.File.separator+ folderName; java.io.File f = new java.io.File(temp); f.mkdirs(); }
}
在Java程序中获取当前运行程序的路径
import java.io.*;
public class Test {
public static void main(String[] args) {
File directory = new File(".");
try {
File newPath = new File(directory.getCanonicalPath()+"NewFolder");
newPath.mkdir();
}catch(Exception exp)
{
exp.printStackTrace();
}
}
}
//File directory = new File(".");
//directory.getCanonicalPath();取得当前路径
