How to remove line break from text?

Question

Java

There is a file with text like

"
A1,
B2,
B3,
...
"

I read the file like this:

String text = "";
try {
 FileReader fr = new FileReader("file.txt");
 int c;
 while((c = fr.read())> 0){
  text = text.concat(String.valueOf((char)c));
 }

} catch (Exception ex) {
 ex.printStackTrace();
}

The text variable turns out to be multiline and I can't process it normally. I need to split it into smaller lines and put them in an array, I tried like this:

String[] BukviArray = text.replace("\n","").split(", ");

Can you please tell me how to remove all line breaks from text ?

You're reading wrong. Read immediately line by line using https://docs.oracle.com/javase/8/docs/api/java/io/...
