Check whether a file is a directory in Java
The method java.io.File.isDirectory() checks whether a file with the specified abstract path name is a directory or not. This method returns true if the file specified by the abstract path name is a directory and false otherwise.
A program that demonstrates this is given as follows −
Example
import java.io.File;
public class Demo {
public static void main(String[] args) {
try {
File file = new File("demo1.txt");
file.createNewFile();
System.out.println("Is directory? " + file.isDirectory());
} catch(Exception e) {
e.printStackTrace();
}
}
}The output of the above program is as follows −
Output
Is directory? false
Now let us understand the above program.
The method java.io.File.isDirectory() checks whether the file is a directory or not and the boolean value that is returned by the method is printed. A code snippet that demonstrates this is given as follows −
try {
File file = new File("demo1.txt");
file.createNewFile();
System.out.println("Is directory? " + file.isDirectory());
} catch(Exception e) {
e.printStackTrace();
}
