Directory Counter in Java

Here is a simple example for directory counter. This example will just count the directory/folders where the .class file be. For example the .class will be in the root directory or in C:/ directory it will count all the folders in it excepts sub-folders.

import java.io.File;

public class DirCount{

static int count = 0;

public static void main(String[] args){

if(args.length == 0){

System.out.println("Usage : DirCount <FolderPath>");

System.exit(0);

}

try{

File f = new File(args[0]);

File[] fs = f.listFiles();

for(File ff : fs){

if(ff.isDirectory()){

count++;

}

}

System.out.println("Total Numbers of directories : " + count);

}catch(Exception ex){

System.out.println("Provide proper path");

}

}

}

Write the above program and save it as DirCount.java.

Now compile the program by command javac DirCount.java and execute the class file by java DirCount
