I'm taking an Intro to Java course. Just so happens that both my class and lab are totally online, and I've never done any programming before in my life. I have to write a program that will prompt the user for random characters, and then output that string in a few different ways. The place I'm stuck right now is how to assign some sort of designation to said characters. I know for numbers, to use something like:
double number = input.nextInt();
How would I do that for a string of random letters, numbers, and symbols, to have just one name for all of them?
Also, for one of the outputs, not only do I need to have them in reverse (using stringBuilder.reverse), but only a selected number of characters, with the number being defined by the user (as shown in the example above). Where would I insert the variable "number" into stringBuilder.reverse to make it do that properly?
