    Default Use of UserInput.read () ?

    Hi all,

    Teaching myself Java for an exam coming up next month and in the notes I'm using they have "UserInput.readInt()" as well as "UserInput.readFloat()" - Now in the notes all that's there is a comment which reads /*read user input*/ but that is all. The code is just a small sample from a larger peice of code which is never referenced and i can't find any info online relating to this command. I was wondering if anyone knows this (?)function(?), how it works and its usage?

    Any help would be greatly appreciated!

    UserInput is not a class in the standard API, so it might be a class they wrote.

    Or it's a poorly named Scanner, in which case check out the API.

    Scanner (Java Platform SE 6)

    Well, you tell me- is that a method in the Scanner class? Are you sure you're reading it right?

    Also, maybe you aren't supposed to care what UserInput is. Maybe that's the point- it could be a GUI, a Scanner, a file, or something else.

    Well it does cover scanners and buffers later in these notes. I think maybe its just a terribly named scanner like you suggested. I kinda hoped it wasn't though
    I wish he'd put more of the program its sampled from in or explained it better.

    It doesn't really matter, does it? As long as you know the method signature and return value...?

    That's the way API's work - if you call method X on class Y, you get result Z.
