carriage return

[Manuel Paco]

Hi,
I would like to find out if my String "str" contains carriage return.
Would you take a look please what I am doing wrong .

if ( charInString("\000d", str) )
out.print( "I have found a Carriage return" );

public boolean charInString(String c, String s)
{
for (int i = 0; i < s.length(); i++)
{ if (String.valueOf(s.charAt(i)) == c) return true;
}
return false;
}

I tried doing something like using:

String NewLine = System.getProperty("line.separator") ;

but the problem with this was that I still needed to know what platform I was running on. Since unix, windows, mac all use different control charactors.
I finally got my code to work but it is hardcoded for unix.

Try this:

String line = "some input from eg a textarea";
int pos = line.indexOf(0x0D);
if(line.charAt(pos) == 0x0A) {
   /* some code */
}

0x0D = carriage return characters
0x0A = line feed

if (str.indexOf(System.getProperty("line.separator")) > -1) {
  System.out.println("line-seperator found");
}

Is that what you were thinking of?

[Manuel Paco]

Thank you very much, but my code still does not work.
(I run Windows 2000)
I am using String that I got from JTextArea
and I still can't find any carriage return in my string even it is there.
I've tried everything you advised.
Do you have any more ideas?

[Manuel Paco]

I forgot to mention that the carriage return was
made by
out.println("");

[William Barnes]

if (str.indexOf(System.getProperty("line.separator")) > -1) 
{
  System.out.println("line-seperator found");
}

Ya, that looks good. Thanks.

Use .equals() not == to compare two strings.

[Dave Landers]

And actually, if you want to search for one string within another, look at the String.indexOf() method.

Manuel,
can you please post your current code and a simple testcase which fails but you want to pass? Thanks!
