public class DirectoryHtmlFiles {
    
}

// Directory of .HTML files. 

class DirListOnly { 
  public static void main(String args[]) { 
    String dirname = "C:\\Users\\Admin\\Documents\\NetBeansProjects\\JavaWeb\\web"; 
    File f1 = new File(dirname); 
    FilenameFilter only = new OnlyExt("html"); 
    String s[] = f1.list(only);
    for (int i=0; i < s.length; i++) { 
      System.out.println(s[i]); 
    } 
  }

however it gives the error

Solution 1

This looks very similar to FilenameFilter - sample program in Java[^], which you should check for correct copying.

Very useful problem analysis - not.

probably something to do with file path which changed several times

package javas;

import java.io.File;
import java.io.FilenameFilter;

public class DirectoryHtmlFiles {

	public static void main(String a[]){
                int Count = 0;
		File file = new File("C:\\Users\\Admin\\Documents\\NetBeansProjects\\JavaWeb");
		String[] files = file.list(new FilenameFilter() {
			
			@Override
			public boolean accept(File dir, String name) {
				if(name.toLowerCase().endsWith(".html")){
					return true;
				} else {
					return false;
				}
			}
		});
		for(String f:files){
                        Count++;
			System.out.println(f);
                        System.out.println(Count);
		}
	}

prints JsCounts.html
