Long story short. I need to code this so that if the user does not have 2.00, it prompts them a message saying so and ask them to pick a different type of roll.. however, I cannot figure out how to allow the user to input something that will be used for the switch statement.. the switch statement is switch(uc) if that helps.. I've tried half a dozen things, and nothing can work. This is what i currently have.



I had a while loop, but wouldnt work. I had something like

input.next().equals(uc);

you realize that doesn't actually do anything right?

no. i honestly thought it would set the user's input equal to the string uc.

nvm

doesn't work. I need to somehow turn the input, into one of the five case statements.

how do you know what the 5 case statements are? what are your possible inputs? then figure out how to map them

I have tried several different ways to get the user's input register as a string. as the case statements, as the switch itself.. is there any tip you could give.. Am I trying to use the user's input as a string? as a case? Im just at the moment.

do something like that

uc = input.next().trim().toLower();
System.out.println("uc=" + uc);
System.out.println("uc.equals double=" + uc.equals("double"));
System.out.println("uc == double=" + (uc == "double"));
switch (uc){
...
}

what does the print statement say?

i'm new to the switch with strings in java. i think this was just a recent addition in java 7 maybe? i learned java 5 and haven't kept up with the new stuff much. back when i learned it, you could only use it with primitive integer values (byte, short, char, etc) and not with objects. does switch use the == comparison or does it invoke .equals? if the latter, does it work for all objects or only strings? if the former and it's coming from user input, probably the == doesn't work. so if you're having problems with switch, try using if/else

Ugh... I just think its a simple 1-2 line that I need.. Your above statement is too much. Lots of println's i dont need. The code is as it needs to be, with the one exception that at this section of code :



There has to be some way to take user's input and translate it into the switch that enables the cases.

/e The part input.next(); I just have a feeling its something very simple.
as far as using if/else statements goes.. I did the entire thing originally with if / else and it was a nightmare.. switch with cases makes the code cleaner and easier to manage.

oh. i thought you had a problem with the switch/case itself.

uc = input.next();

then make sure your switch is inside the loop so that it goes back to the switch at the next iteration
