Answer 1

The firstly you have to read line from file and after this split read line, so your code should be like:

FileInputStream fstream = new FileInputStream("your file name");
// or using Scaner
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null)   {
  // split string and call your function
}
