Write File Java Using Read All Bytes Data

Write File Java Using Read All Bytes Data

In this sample java you will how to read file and write it to different file. We will use Java 7 new feature of write file using java.nio.file.Files class as shown below:

Java Class:

package com.javahonk;

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class WriteFileUsingReadAllByteData {

	private final static String WRITE_TO_FILE_NAME = "C:\\JavaHonk\\File\\WriteToFile.txt";
	private final static String READ_TO_FILE_NAME = "C:\\JavaHonk\\File\\JavaHonk.txt";

	public static void main(String args[]) throws IOException {

		File writeToFile = new File(WRITE_TO_FILE_NAME);
		Path writeFilePath = Paths.get(WRITE_TO_FILE_NAME);
		Path readFilePath = Paths.get(READ_TO_FILE_NAME);

		if (!writeToFile.exists()) {
			writeToFile.createNewFile();
		}

		byte[] buf = Files.readAllBytes(readFilePath);
		Files.write(writeFilePath, buf);

	}

}
