Here’s an example to check if a directory is empty.

Example


package com.mkyong.file;

import java.io.File;

public class CheckEmptyDirectoryExample
{
    public static void main(String[] args)
    {	

	File file = new File("C:\\folder");
		
	if(file.isDirectory()){
			
		if(file.list().length>0){
				
			System.out.println("Directory is not empty!");
				
		}else{
				
			System.out.println("Directory is empty!");
				
		}
			
	}else{
			
		System.out.println("This is not a directory");
			
	}
    }
}
