public void randomGen(String[] x) {
int rand = rangen.nextInt(x.length-2);
JOptionPane.showMessageDialog(null, "Randomly chosen word is: " + x[rand]);
}

For anyone...

Would this be the proper way to use this utility?


public void randomGen(String[] x) {
Random rangen = new Random();
int rand = rangen.nextInt(x.length-1);

}

Not too sure if this is the right place to post this, so if it isn't, I apologize. Still figuring out my way around here.

Anyways, what is the best way to grab a random element from an array?...

I will agree with Norm. If you only need a quick variable for a function inside a method, instantiate it within the method. Otherwise, if you need multiple methods to use a single variable, or a...

I was confused by what Norm is trying to say when he posted it in my post. Basically, whenever you want to see if a variable is being assigned to something, use a println to say ("Assigned variable...

Jumping the gun on trying to make the GUI is always a bad idea. Make your methods work and your logic correct before you try to make it look pretty. What compiler are you using? Also, it might be...

varlib.tableA[i] = readIn;

Stupid mistake, but the code works. Thanks for pointing me in the right direction!

public void popTableAArray() {
String readIn;

try{
BufferedReader br = new BufferedReader(new FileReader("tableA.txt"));
System.out.println("For...

Placed the file in the root directory, and changed the println to show the values of readIn. Still outputs my Else first, and still shows the values of the txt file as null. There are no other files...

You're asking the wrong guy. What are you talking about "where the null file is?" Would it not show a IO Error if it loaded a file that doesn't exist? My pathing is entirely correct. I'll try putting...

This code:

There is only one text file in the specified directory. It's formatted as such

The oracle document states that reader will return:

Alright, I've been plugging away at this code for quite some time. I finally felt it necessary to seek assistance in an online forum, as my JAVA mentor is away for the time being.

My idea is to...
