java - Writing a "\t" to a text file creates a line? -

i'm writing 2 textfiles , wanted eaiser way read textfiles without words , number laying close eachother chose write them tab seperate them. when class linenumberreader seems think tab new line.

i have 2 classes. textwriting , comparetextfiles

when run textwriting class can output this:

(1)       word1
(2)       word2
(3)       word3

so working intended. (i used spaces formatting purposes, file contains tabs correctly)

and in other class comparetextfilesi compare 2 textfiles wrote first class. important code this.

string word,word2; int i; lnr = new linenumberreader(new filereader(file)); while (sc.hasnext() && sc2.hasnext()) {                     word = sc.next();     word2 = sc2.next();                     lnr.readline();     if (word.equalsignorecase(word2)) {         = lnr.getlinenumber();         system.out.println("line number: " + + " , word: [" + word + "]" + " , word " + "[" + word2 + "]" + " same!");                         }     else         system.out.println("[" + word + "]" + " , " + "[" + word2 + "]" + " not same"); } 

the output recieving is:

line number: 1 , word: [(1)] , word [(1)] same!
line number: 2 , word: [asd] , word [asd] same!
line number: 3 , word: [(2)] , word [(2)] same!
line number: 3 , word: [yeye] , word [yeye] same!
line number: 3 , word: [(3)] , word [(3)] same!
line number: 3 , word: [he] , word [he] same!

why stuck on 3 many times, , tab create new line of sort?

your code calls linenumberreader.readline every scanner token. presuming a) each scanner uses default delimiter (in case each line has 2 tokens) b) linenumberreader.readline increments value returned linenumberreader.getlinenumber until the file has been read - each token (rather each line) increment until 3 lines read (and stop incrementing), resulting in output get.

an alternative suggestion (there many ways skin cat): consider using 2 scanner's read files, reading files using scanner.readline method. each line, increment variable representing line number , parse lines needed.

int linecount = 0; while ( sc.hasnextline() && sc2.hasnextline() ){     linecount++;     string line1 = sc.nextline();     string line2 = sc2.nextline();     //parse lines     string[] line1tabs = line1.split("\t");     //etc... }
