code copy

import com.google.common.io.InputSupplier;
import com.google.common.io.Files;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
.......
.......

public void copyFile(File pathfile, String fileName, final InputStream in) throws IOException {
    Files.copy(new InputSupplier<InputStream>() {    
    @Override
        public InputStream getInput() throws IOException {
            return in;
        }
    }, new File(pathfile, fileName));
}

การเรียกใช้

File dir = new File("c:\\temp\\");
InputStream stream = new FileInputStream(new File("helloworld.txt"));
copyFile(dir, "helloworld.txt", stream);

แค่นี้ก็เป็นอันเรียบร้อย
