FileDemo.java
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class FileDemo
{
    public static void main(String[] args) throws IOException
    {
        FileDemo fileDemo = new FileDemo();
        fileDemo.copyFile("D:/work/hello.txt", "D:/work/New_hello.txt");
    }

    private void copyFile(String srcFileName, String destFileName)
            throws IOException
    {
        InputStream is = null;
        OutputStream os = null;

        try
        {

            File srcFile = new File(srcFileName);
            File destFile = new File(destFileName);

            is = new FileInputStream(srcFile);
            os = new FileOutputStream(destFile);

            byte[] buffer = new byte[1024];

            int length;
            // copy the file content in bytes
            while ((length = is.read(buffer)) > 0)
            {
                os.write(buffer, 0, length);
            }

            System.out.println("File is copied successful!");

        }
        finally
        {
            if (is != null)
            {
                is.close();
            }
            if (os != null)
            {
                os.close();
