Reading one line

Question

I am trying to read from a file using a Scanner:
input = new Scanner(new File("data.txt"));
// change delimiter in the case some tokens might have a space or a slash
input.useDelemiter("[,]");
while(input.hasNext())
System.out.prinln(input.next());
}The file looks something like this
Bob,Steve,Pam,Sam,Sue
Jones,Doe,StoneI am new to Java. I'd like to read and print only the first line. How can I make the input to stop at the end of the first line? Thank you.

You can do sth like that:
input = new Scanner(new File("data.txt"));
// change delimiter in the case some tokens might have a space or a slash
input.useDelemiter("[,]");
String firstLine = input.nextLine(); //read one line
input = new Scanner(firstLine); //create a new Scanner object for the read line
input.useDelemiter("[,]");
while(input.hasNext())
System.out.prinln(input.next());
}
