Checking for a FileNotFoundException in a Seperate Method
This is just a simple program to check if a file exists or not, with the user input and the results 'File exits'/'File does not exist' all in the main method and the actual Exception catching being done in a separate method. I've got the basics of the doesFileExist method to catch any exceptions, but I can't figure out how to return that information to the main method so I can inform the user of the results.

How do you validate a String to make the program continue or not?
I'm not sure if this should be in two separate posts or not. So, I apologize ahead of time if this is the case. However, since I'm trying to do one thing here with two conflicting methods, I thought it should go together.

How to get a random between 1 - 100 from randDouble?
Hello,
Okay, I'm still fairly new to Java. We've been given an assisgnment to create a game where you have to guess a random integer that the computer had generated. The problem is that our lecturer is insisting that we use:
double randNumber = Math.random();
And then translate that into an random integer that accepts 1 - 100 inclusive. I'm a bit at a loss. What I have so far is this:
