Hallo. Hat einer einen kurzen Befehl, wie ich in Java eine existierende Datei von a nach b kopieren kann?
package de.itlantik;
package de.itlantik;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.channels.FileChannel;
public class FileUtils
{
public static void copyFile(File file, String newFilePath)
{
if (file.exists() && file.canRead())
{
File newFile = new File(newFilePath);
if (newFile.exists())
{
newFile.delete();
}
FileInputStream inputStream = null;
FileOutputStream outputStream = null;
FileChannel inputChannel = null;
FileChannel outputChannel = null;
try
{
inputStream = new FileInputStream(file);
outputStream = new FileOutputStream(newFile);
inputChannel = inputStream.getChannel();
outputChannel = outputStream.getChannel();
inputChannel.transferTo(0, inputChannel.size(), outputChannel);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{
try
{
if (inputStream != null) inputStream.close();
if (outputStream != null) outputStream.close();
if (inputChannel != null) inputChannel.close();
if (outputChannel != null) outputChannel.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
}
public static void main(String[] args) throws IOException
{
File fileToCopy = new File("abc.txt");
fileToCopy.createNewFile();
copyFile(fileToCopy, "bbc.txt");
}
}
Herzlichen Dank für die
