Question

The code I want to read from is called “textfile.txt”, now how do I pass this file as an argument in a parameter?

Pseudo code:

 readsomething(textfile);

 void readsomething(String reading) {

 Scanner input = new Scanner(new File(reading));
 bla bla bla
 bla bla bla

 }

I have tried several variations of the above code, every time I get an error saying identifier is requires for readsomething(textfile);

Answer 1

readsomething(textfile);

i am assuming that textfile parameter is a String (path to the file like “C:/abcfile.txt”).

Scanner input = new Scanner(new File(reading));
String line;
while((line=input.nextLine())!=null){
    System.out.println(line);
}
