Datei download, verschieben und umbennen -> Welche Fehler

[t-bone-hd-990d]

Hallo,

heute hab ich mein erstes Programm zusammengebastelt.

Hab nur 10 Fehler *grins*

Was war mein Fehler bzw. wie wird die txt Datei richtig verschoben

Könnt ihr euch meine Code ansehen, da ich leider totaler Anfänger bin und lieber VB programmiere.

Code:

/**
*
*
*
*
* @********
*
*/

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.channels.ByteChannel;
import java.nio.channels.FileChannel;




//Datei runterladen

URL bild = new URL("http://webserver.de/shfjhwiue.txt");
InputStream in = bild.openStream();

byte[] buffer = new byte[8192];

FileOutputStream out = new FileOutputStream(new File("shfjhwiue.txt"));

int _tmp = 0;

while((_tmp = stream.read(buffer)) > 0){
out.write(buffer, 0 , _tmp);
}

//Danach Datei verschieben in "C:\USERNAME\Test\Unterordner\"

public class FileCopy {
long chunckSizeInBytes;
boolean verbose;
public FileCopy(){
this.chunckSizeInBytes = 1024 * 1024; //Standard: Buffer 1MB
this.verbose = false; //Statistics about Copy Process
}
public FileCopy(boolean verbose){
this.chunckSizeInBytes = 1024 * 1024; //Standard: Buffer 1MB
this.verbose = verbose; //Statistics about Copy Process
}
public FileCopy(long chunckSizeInBytes){
this.chunckSizeInBytes = chunckSizeInBytes; //Custom Buffer (Bytes)
this.verbose = false; //Statistics about Copy Process
}
public FileCopy(long chunckSizeInBytes, boolean verbose){
this.chunckSizeInBytes = chunckSizeInBytes; //Custom Buffer (Bytes)
this.verbose = verbose; //Statistics about Copy Process
}
public void copy(File source, File destination) {
try {
FileInputStream fileInputStream = new FileInputStream(source);
FileOutputStream fileOutputStream = new FileOutputStream(destination);
FileChannel inputChannel = fileInputStream.getChannel();
FileChannel outputChannel = fileOutputStream.getChannel();
transfer(inputChannel, outputChannel, source.length(), false);
fileInputStream.close();
fileOutputStream.close();
destination.setLastModified(source.lastModified());
} catch (Exception e) {
e.printStackTrace();
}
}
public void transfer(FileChannel fileChannel, ByteChannel byteChannel, long lengthInBytes, boolean verbose)
throws IOException {
long overallBytesTransfered = 0L;
long time = -System.currentTimeMillis();
while (overallBytesTransfered < lengthInBytes) {
long bytesTransfered = 0L;
bytesTransfered = fileChannel.transferTo(overallBytesTransfered, Math.min(chunckSizeInBytes, lengthInBytes - overallBytesTransfered), byteChannel);
overallBytesTransfered += bytesTransfered;
if (verbose) {
System.out.println("overall bytes transfered: " + overallBytesTransfered + " progress " + (Math.round(overallBytesTransfered / ((double) lengthInBytes) * 100.0)) + "%");
}
}
time += System.currentTimeMillis();
if (verbose) {
System.out.println("Transfered: " + overallBytesTransfered + " bytes in: " + (time / 1000) + " s -> " + (overallBytesTransfered / 1024.0) / (time / 1000.0) + " kbytes/s");
}
}
}

// Datei umbennen

File source = new File("shfjhwiue.txt");
File destination = new File("shfjhwiue.exe");
(!source.renameTo(destination)){
}


out.close();

Moin,

wenn Du die Code-Tags benutzen würdest (#-Button im Editor resp. den Code mit [_JAVA_][/_JAVA_] ohne die Unterstriche klammerst) und vor allem mal beschreibst, wo welchen Fehler Du redest, hättest Du auch eine Chance, dass sich das mal jemand hier anschaute

So ist es reine Rätselraterei

Zudem hast du ne While außerhalb jeder Methode, und der Source hört mitten in der Klasse auf.

Yeep - tut es

Gesetzt den Fall, dass DIES wirklich Dein Codeanfang ist:

/**
 * 
 *
 * 
 *
 * @********
 * 
 */
 
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.channels.ByteChannel;
import java.nio.channels.FileChannel;




//Datei runterladen

URL bild = new URL("http://webserver.de/shfjhwiue.txt");
InputStream in = bild.openStream();

byte[] buffer = new byte[8192];

FileOutputStream out = new FileOutputStream(new File("shfjhwiue.txt"));

int _tmp = 0;			        			      
			     
while((_tmp = stream.read(buffer)) > 0){
	out.write(buffer, 0 , _tmp);
}

//Danach Datei verschieben in "C:\USERNAME\Test\Unterordner\"

public class FileCopy {
long chunckSizeInBytes;
...........

dann kann es auch nicht klappen, da - wie Kai008 schon schrieb - hier noch einiges im Code fehlt!
Alles nach Deinen Imports MUSS in einer Hauptklasse für die Anwendung eingebettet !
Das hängt so alles im luftleeren Raum ....
