Java string not equals

Question

So I have String array

String[] faculties = new String[21];

and I need to fill it with the names of faculties from .txt file that looks like

Math & CS; First Speciality; First Program; etc

Math & CS; Second Speciality; First Program; etc

Math & CS; Second Speciality; Second Program; etc

Physics; First Speciality; First Program; etc

Physics; First Speciality; Second Program; etc

I use the next code to get these names

FileReader input = new FileReader("faculties1.txt");
BufferedReader bufRead = new BufferedReader(input);
String myLine;
int f = 0;
 while((myLine = bufRead.readLine())!= null){
 String[] arr = myLine.split(";");
 if(f == 0){
 faculties[f] = arr[0];
 f++;
 }
 else{
 if(!faculties[f-1].trim().equals(arr[0].trim())){
 faculties[f] = arr[0];
 f++;
 }
 }
 }

but when I try to check my array

for(int i = 0; i < f; i++){
 System.out.println(faculties[i]);
 }

console says me

Math & CS

Math & CS

Physics

I dont get why Java puts "Math & CS" second time to my array.

• litelite: Did you try to step through it with a debugger?
• slxvxBatih: @litelite yep. this if(!faculties[f-1].trim().equals(arr[0].trim())) returns true when f == 1 even if arr[0] == "Math & CS" and faculties[f-1] == "Math & CS"
• litelite: Maybe some kind of invisible unicode caracter somewhere in the file? You can try to open the file with something like notepad++ or sublime text and activate the show all caracters option.
• Ishnark: Try doing a String.compare on faculties[f-1] and arr[0]? If that returns anything other than 0, there's a character issue, as @litelite says
• slxvxBatih: @litelite thank you much! I used UTF-8 .txt in my project to see cyrillic symbols in console, but when I changed .txt to ANSI console said me Math & CS Physics

Answer 1

I tried this it is worked fine and output returns as you expected I think, anyhow you need to throws exceptions.

Math & CS
Physics

According to me there can be,

mispelled character in your text file. Check using different text-editor rather than windows notepad.

UPDATE:

After added this answer I saw your last comment in question that your problem solved.
