public void decrement(int decrease)
{
    decrease--;
}

}

can anyone help me with whr to ask the user to input the displayPrice? then how to detect it which range it is? ><
and how to create the main for it to work ?
help with the coding k? guys :(
thanks alot!

where to ask for input: that would depend on where YOU want he input.
detect in which range it is .. use the operators <, = and > and you'll have it to work in no time.

creating a main method is the very most basic thing in Java. you wouldn't even be able to get a 'HelloWorld' class to say 'Hello' without one, so I'm sure you'll have an example somewhere.

This looks a lot like you've just copied your assignment here, while we're not here to do your homework for you.
