Please help me!!

Answer 1

Here you have two lists :

• A list of entries coming from the file you are reading, each entry is read in "line" String.
• A list of values you have input in a JTextArea separated by "\\n".

First of all, you propably need to check if you have the same number of entries in the both lists. You also need to split your String scanner using "\\n" as the separator.

As you are reading line by line, you can also use the following code which won't check if the number of entries are equals :

 int index = 0; String[] ids = scanner.split("\\n"); while ((line = br.readLine()) != null) { String[] actionID = line.split("\\\\\\",\\""); String custnumber = actionID[3]; String fullname = actionID[18]; String add1 = actionID[19]; if (ids.length > index) { lbwp.write("\\"" + custnumber + "\\",\\"" + fullname+ "\\"," + "\\"" + ids[index] + "\\"," + "\\n"); } else { lbwp.write("\\"" + custnumber + "\\",\\"" + fullname+ "\\"\\n"); } index++; } 

EDIT: replace the condition
