File class

Posted by Johny on September 11, 2001 at 7:24 AM

[javacode]
import java.io.*;
public class CheckFile
{
public static void main(String[] args)
{
File f = new File("data.txt");
if(f.exists())
{
System.out.println(f.getName() + " exists");
System.out.println
("The file is " + f.length() + "bytes long");
if(f.canRead())
System.out.println(" ok to read");
if(f.canWrite())
System.out.println(" ok to write");
}
else
System.out.println("File does not exit");
}
}
[/javacode]

In the above is the data type of f File?

Is File a class?

new File creates an instance of the File class. This instance is the object data.txt, am i correct?

f.exists, f.getName etc they are methods arent they?
