txt empty string removal
Sep 1^st, 2009, 1:57pm

Hello again! I'm trying to make function to remove empty strings in txt file. It removes only 1 empty string between not empty strings.
And the thing I can't make is removal several empty strings successively - it doesn't want to see empty string in front of current "i" Here is the code:
Code:



String lines[] = loadStrings("loadsomefile.txt");
String[] neww = new String[lines.length];
String currentString = "";
String str1 = "";
String str2 = null;

for (int i = 0; i < lines.length-1; i++) 
{
  currentString = lines[i];

  if(currentString.equals(str1) == true || currentString.equals(str2) == true  ) {
    currentString = lines[i] + lines[i+1];
    neww = append(neww,currentString);
  }
}
saveStrings("recordsomefile.txt",neww);

I see that it recreates empty strings again, but I'm stumped
If you have some time, please take a look at the code above.

Code:

String lines[] = loadStrings("loadsomefile.txt");
String[] neww = new String[1]; // or [lines.length / 2] for example

for (int i = 0; i < lines.length; i++) 
{
  if (!lines[i].equals("")) {
    neww = append(neww, lines[i]);
  }
}
saveStrings("recordsomefile.txt",neww);

(Untested...)
