Thread: Moving files to a single list iteratively

Hello Growler,

Welcome to the forums.

I have some time on my hands so here is a good example to get you going..

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;
 
public class TxtFiles {
 
	/**
	 * JavaProgrammingForums.com
	 */
 
	// Directory path here
	public static String path = ".";
 
	public static void main(String[] args) {
		listFiles();
	}
 
	public static void listFiles() {
 
		String files;
		File folder = new File(path);
		File[] listOfFiles = folder.listFiles();
 
		for (int i = 0; i < listOfFiles.length; i++) {
			if (listOfFiles[i].isFile()) {
				files = listOfFiles[i].getName();
				if (files.endsWith(".txt") || files.endsWith(".TXT")) {
					// Lists files in console
					System.out.println(files);
					openFile(files);
				}
			}
		}
	}
 
	public static void openFile(String file) {
 
		try {
			FileInputStream in = new FileInputStream(file);
			BufferedReader br = new BufferedReader(new InputStreamReader(in));
			String strLine;
 
			while ((strLine = br.readLine()) != null) {
				// Prints content of file to console
				System.out.println(strLine);
				// Write file method needs to go here
			}
 
		} catch (Exception e) {
			System.out.println(e);
		}
	}
 
}

This code lists all the .txt files in a directory. It then opens them one by one and displays their content.

You will need to figure out how to write the content to a single file.
