Put tabs into Strings

Thread view:

feju2000@gmx.de - 17 Jan 2006 23:00 GMT

Hallo,
ich habe ein Problem, was mich wirklich verrückt macht.
Als erstes lese ich Strings aus einer tab-separierten Datei.
Ein Parameter namens cutchar gibt an, welcher String separiert.
Da es sich bei "\t" um einen regulären Ausdruck handelt, muss ich zum
Parsen die Klasse Pattern benutzen.
Das funktioniert auch noch alles!
Wenn ich allerdings versuche, den Parameter cutchar (auch gern mithilfe
der Klasse Pattern) zu einem String (um diesen zu separieren)
hinzuzufügen, geht es einfach nicht.
Ich habe schon einiges ausprobiert, es geht aber einfach nicht!

                    StringBuffer out = new StringBuffer("");
                    String delim = Pattern.compile(delimiter).toString();
                    out.append((String)(s.x(i)));
                    out.append(delim);
                    out.append(tagString);
                    bw.write(out + "\n");

geht also nicht!!!
Habt ihr irgendwelche Vorschläge?

Danke,
Felix

Mein Vorschlag würde auf englisch, meine Bablel Fische schreiben sollen,
in meinem Ohr, versteht nicht Ihren deutschen Dialekt. Ich benötige mehr
Code als, was Sie für diese Frage gegeben haben.

Thanks in Advance...

Ich verstehe nicht Ihre Beschreibung des Problems.
Und, der Code, der angebracht wird, ist wegen der
unbekannten Symbole wie ' delim ', ' s, ' x ' usw. unverständlich.
Außerdem statement:
String delim = Pattern.compile(delimiter).toString();
ist ungewöhnlich und sonderbar.

Okay, next try in English:
I just want to separate some Strings with a tab.
The tab is in the String delim and looks like "\t"!
The Problem is, that if I write the String down in a file, the lines
are not Tab-separated but written together just with a \t between them!

are you writiing "xxx\\txxxx" in your program? It should be just
"xxx\txxx"

It depends on your viewer how that tab is displayed. Use a hex viewer
to make sure the file is correct.

No, I am writing "xxx\txxxx" and in the file it's also "xxx\txxxx"!

What was it in hex? 09, that is correct. 5C 74? then your \t literal
is not being interpreted. \t only works in a literal in quotes in
source code. It wont work if you wrote (char)0x5c + ( char )0x74 to
the output file.

Okay, but I get the separating (in this case \t) String from a gui as
input.
How shall I parse (or format) the input to get a real tab in the
resulting file?

Thanks

Please talk in hex. Otherwise every thing you say is ambiguous.

String.replace ( "\\t", "\t") is what you want.

Hi,
the problem is, that it is 5C 74 in hex!
But I cannot just use String.replace ( "\\t", "\t"), because the
separating String maybe also for example \s or whatever.
The question now is, how to parse a "\t" which is 5C 74 in hex to a
"\t" which is a 09 in hex???

maybe you want it expanded to spaces? I wrote an old dos utility to
do that still works under windows. See
http://mindprod.com/jgloss/tabout.html
I have also written a java one. It is the old C one that is posted
though.
