Thread: java program to copy a text file to onother text file

Just invoke a batch file to copy the file, or use the OS gui to copy the file for you.

If it must be in Java, use the BufferedWriter and FileWriter classes to write out to a file, and Scanner or BufferedReader/FileReader to read in

BufferedWriter writer = new BufferedWriter(new FileWriter("test file.txt"));
writer.append("this is some test text.");
writer.flush();
writer.close;

Scanner reader = new Scanner("test file.txt");
System.out.println("First line read: ");
System.out.println(reader.nextLine());

Hey francoc,

Welcome to the forums

How about this?

import java.io.*;
import java.util.Scanner;
 
public class FileProgram {
 
	public static void main(String[] args) throws Exception {		
		readFile();
	}
 
	public static void readFile() throws Exception {
 
		// Location of file to read
		File file = new File("data.txt");
 
		Scanner scanner = new Scanner(file);
 
		while (scanner.hasNextLine()) {
			String line = scanner.nextLine();
			//System.out.println(line);
			writeFile(line);
		}
		scanner.close();
		System.out.println("File Copied"); 
	}
 
	public static void writeFile(String copyText) throws Exception {
 
		String newLine = System.getProperty("line.separator");
 
		// Location of file to output
	    Writer output = null;
	    File file = new File("date_output.txt");
	    output = new BufferedWriter(new FileWriter(file, true));
	    output.write(copyText);
	    output.write(newLine);
	    output.close();		
	}
