We can use Channel to copy file content faster. To do so, we can use transferTo() method of FileChannel .
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.channels.FileChannel;
public class FileCopier {
public static void main(String[] args) {
File sourceFile = new File("hello.txt");
File sinkFile = new File("hello2.txt");
copy(sourceFile, sinkFile);
}
public static void copy(File sourceFile, File destFile) {
if (!sourceFile.exists() || !destFile.exists()) {
System.out.println("Source or destination file doesn't exist");
return;
}
try (FileChannel srcChannel = new FileInputStream(sourceFile).getChannel();
FileChannel sinkChanel = new FileOutputStream(destFile).getChannel()) {
srcChannel.transferTo(0, srcChannel.size(), sinkChanel);
} catch (IOException e) {
e.printStackTrace();
}
}
}
