Reading Text File

[papaboy2]

hi, how can i read a text file and remove blank space between two lines? how can i concat the first message and second message without putting the blank space between them. thank you very much.

for example:

[Message] This my message but the next message is between blank space

Message is continued here


my code is :

BufferedReader input = null;
try {
//reads one line at a time
input = new BufferedReader( new FileReader(aFile) );
String line = null; //not declared within while loop
while (( line = input.readLine()) != null){
System.out.println(line);
}
}
catch (FileNotFoundException ex) {
ex.printStackTrace();
}

If you're using the new J2SE 5.0 (1.5.0), you can use Scanner
which is way easier to use than BufferedReader.

Or else, you could just check to see if line contains any text and only output when text is seen.

 while (( line = input.readLine()) != null){
   [red]if (!line.equals(""))[/red]
     System.out.println(line);
}

I would maybe hange that slightly to :

if (!line.trim().equals(""))

while (input.hasNextLine()) {
String name = input.nextLine();
printString(output, name);
