//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[/b]Java[/b]程序中获取当前运行程序的路径[/b][/b]
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
