Given a string that isn\'t too long, what is the best way to read it line by line?

I know you can do:

BufferedReader reader = new BufferedReader(new          


        

Answer 1

You can try the following regular expression:

\r?\n

Code:

String input = "\nab\n\n    \n\ncd\nef\n\n\n\n\n";
String[] lines = input.split("\\r?\\n", -1);
int n = 1;
for(String line : lines) {
    System.out.printf("\tLine %02d \"%s\"%n", n++, line);
}

Output:

Line 01 ""
Line 02 "ab"
Line 03 ""
Line 04 "    "
Line 05 ""
Line 06 "cd"
Line 07 "ef"
Line 08 ""
Line 09 ""
Line 10 ""
Line 11 ""
Line 12 ""
