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
