Copy File from Directory to Another

In this tutorial you will learn how to copy file from one location to another location

Copy File from One Location to Another

To Copy a file from one location to another location open a FileInputStream and FileOutputStream reference variable from the source and desination file respecivly.

FileInputStream fileInputStream = new FileInputStream(sourceFile);
FileOutputStream fileOutputStream = new FileOutputStream(destinationFile);

Make an Array of byte and read from one stream to a buffer and write to another stream

int bufferSize;
byte[] bufffer = new byte[512];
   while ((bufferSize = fileInputStream.read(bufffer)) > 0) {
   fileOutputStream.write(bufffer, 0, bufferSize);
}

The Following is a complete code to Copy file from one location to another location

CopyFileExample.java

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class CopyFileExample {
	public static void main(String[] args) {
		try {
			File sourceFile = new File("D:\\registration.jsp");
			File destinationFile = new File("F:\\" + sourceFile.getName());
			CopyFileExample copyFileExample = new CopyFileExample();
			copyFileExample.copyFile(sourceFile, destinationFile);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public void copyFile(File sourceFile, File destinationFile) {
		try {
			FileInputStream fileInputStream = new FileInputStream(sourceFile);
			FileOutputStream fileOutputStream = new FileOutputStream(
					destinationFile);

			int bufferSize;
			byte[] bufffer = new byte[512];
			while ((bufferSize = fileInputStream.read(bufffer)) > 0) {
				fileOutputStream.write(bufffer, 0, bufferSize);
			}
			fileInputStream.close();
			fileOutputStream.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
