Determining if a File or Directory Exist
This is a very simple
problem. You just have to determine whether a file or directory exists or not.
If it exists it returns true otherwise in the else condition, it
retunes vice-versa.
The
following program creates an object of File class and checks
whether the given file exists or not by using exists() method of
the class.
We have used following methods:
exists(): It checks whether the file or directory denoted by this pathname
exists or not.
Code of this program is given below:
import java.io.*;
public class FileOrDirectoryExists{
public static void main(String args[]){
File file=new File("Any file name or
directory whether exists or not");
boolean exists = file.exists();
if (!exists) {
// It returns false if File or directory does not exist
System.out.println("the file or directory
you are searching does not exist : " + exists);
}else{
// It returns true if File or directory exists
System.out.println("the file or
directory you are searching does exist : " + exists);
}
}
}
|
The output of the program is given below:
C:\java>java FileOrDirectoryExists
the file or directory you are searching does not exist : false |
