public class FileCheck {
public static void main(String[] args) {
String filename="d://test.xml";
filename="o://test.xml";
filename="o://t";
filename="o:// learning // learning .txt";
File f=new File(filename);
if (f.exists())
{
if (f.isFile())
{
System.out.println("is file exist ");
}
else
{
System.out.println("is folder exist ");
}
}
else
{
System.out.println("no");
}
System.out.println(checkFileExist(filename));
}
public static boolean checkFileExist(String filename)
{
//String filename="d://test.xml";
//filename="o://test.xml";
File f=new File(filename);
if (f.exists())
{
System.out.println("filename:"+filename+" exist");
return true;
}
else
{
System.out.println("filename:"+filename+" not exist");
return false;
}
}
}
