Hi haba folgendes prob ich möchte das eine TXT datei aus C:\test.txt eingelesen wird und geändert. Habe aber keine ahnung wie ich die datei einlesen kann soweit bin ich erstmal:

class ReplaceDemo
{
public static String replace( String s, String search, String replace )
{
int start = 0, pos = 0;
StringBuffer result = new StringBuffer( s.length() );
while ( (pos = s.indexOf(search, start)) >= 0 )
{
result.append( s.substring(start, pos) );
result.append( replace );
start = pos + search.length();
}
result.append( s.substring(start) );

return result.toString();
}

public static void main( String args[] )
{
String s1 = "Meine datei!!";
String s2 = replace(s1, "a", ".0.");
String s3 = replace(s2, "b", ".00.");
String s4 = replace(s3, "c", ".000.");

try{
Thread.sleep(2000);
}catch(InterruptedException e){}
System.out.print(s81);

}
}

Wie könnte es denn aussehen?

Schau dir mal in der API den BufferedReader fürs lesen und den BufferedWriter fürs schreiben an

Beispiel fürs lesen deiner Datei:

PHP-Code:

 try {
   String temp = null;
   StringBuffer text = new StringBuffer();
   BufferedReader buff = new BufferedReader(new FileReader("C:/test.txt"));
   while ((temp = buff.readLine()) != null) {
      text.append(temp + System.getProperty("line.separator"));
   }
   buff.close();
}
catch (IOException e) {
   System.out.println(e);
} 


kann kleine Fehler (wie ; vergessen oder so ) enthalten, da ich das jetzt schnell zusammengebastelt hab.

Danke für deine Schnelle antwort werde es mal testen.
