java创建文件夹

用java建立文件夹

package test;

public class muluTest
{
public static void main(String[] args)
{
muluTest mulutest = new muluTest();
mulutest.newFolder("D:\\abcds");
}
public void newFolder(StringfolderPath)
{
String filePath = folderPath;
filePath =filePath.toString();
java.io.File myFilePath= new java.io.File(filePath);
try
{
if(myFilePath.isDirectory())
{
System.out.println("the directory isexists!");
}
else
{
myFilePath.mkdir();
System.out.println("新建目录成功");
}
}
catch (Exception e)
{
System.out.println("新建目录操作出错");
e.printStackTrace();
}
}
}
