import java.io.*;

public class CopyFile {
  public static void main(String args[]) throws IOException {
    File fileName = new File("d:/sample.txt");

    FileInputStream inFile = new FileInputStream("d:/sample.txt");
    int fileLength = (int) fileName.length();

    byte Bytes[] = new byte[fileLength];

    System.out.println("File size is: " + inFile.read(Bytes));

    String file1 = new String(Bytes);
    System.out.println("File content is:\n" + file1);

    FileOutputStream outFile = new FileOutputStream("d:/sample-copy.txt");

    for (int i = 0; i < fileLength; i++) {
      outFile.write(Bytes[i]);
    }

    System.out.println("File copied.");
