Scanner and useDelimiter

[Jaqueline Moutton]

I've researched this quite a bit and I just do not understand where I am going wrong, or if it even is an error, and regardless of what the actual problem is how to fix it.


Scenario constants:

Ubuntu 14.10 (GNU/Linux 3.16.0-31-generic i686)
Oracle Java 1.8.0 SDK from webupd8 repository

java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot(TM) Server VM (build 25.40-b25, mixed mode)

import java.io.*
import java.util.*

It seems that in every instance where I try use:

Scanner sc = new Scanner(System.in).useDelimiter("\\n");

or

Scanner sc = new Scanner(System.in).useDelimiter(System.getProperty("line.separator"));

or even the expanded syntax in a full example below:

import java.io.*
import java.util.*

class ChangeDelimiterToRTN{

public static void main(String[] Args){

    String foo;

   Scanner sc = new Scanner(System.in);
   sc.useDelimiter(System.getProperty("line.separator:));

   System.out.println("Enter foo string multiple word: ");
   foo = sc.next();

   System.out.println("String foo entered: " + foo);
   }
}

even valid strings from Oracle's examples such as:

Scanner sc = new Scanner(System.in).useDelimeter("\\s*fish\\s*");

The java compiler will throw an error

ChangeDelimiterToRTN.java:12:error: cannot find symbol = new Scanner(System.in).useDelimeter("\\s*fish\\s*"); symbol: method useDelimeter(String) location: class Scanner 1 error


I've read a few recommendations that I should download and replace the regular expressions library in java with a working regex but before I go through all thatI need to be certain that the issue is not with me.

I've given up on Java many times before because of silly little things like this. I do plan on being a little more proactive this time, I do not know why the strangest things just keep happening between Java and I though.

Have you got another class called Scanner?

Thank you.

No the expanded full example is the entire program. There is only one <Scanner> and only one object [sc]

I am at at a loss.

The error happens even in isolation of the class as a simple program.

Thank you.

Man, do I feel stupid now.

I even though I cut and pasted a few examples in, but I guess the blinders were truly and securely on.

It was posted correctly in three of the four examples in the original post. That is why you should always copy and paste code.
Lost of people make that sort of mistake.
