Any suggestions that would get this run , I would greatlya appreciated it.

To the expression generator.nextInt(n) will evaluate to a random integer between 0 and 1 less than n inclusive.

Determine which of the two randomly generated integers is the arger of the two and display it to the screen in a message:

"The larger of the number ____ and _____ is ____.

Output

The first random number picked was 13.
The second random number picked was 67
The larger of the numbers 13 and 67 was 67

       String input;
       
       Random generator = new Random();
       
       int randNum;
     
       input = JOptionPane.showInputDialog("Please enter a number of your choice");
        randNum = generator.nextInt(-1);

Do not get me wrong.
We are just NOT allowed to do homework, we may help you to go further.
You are supposed to LEARN from this and to IMPROVE yourself.

But I see that you repeatedly ask the same questions.
By now you should know how to write output from a program.

I think you are not learning from this way to ask questions, because you do
not have enough basic knowledge.
Therefore, please first take a basic course in JAVA fundamentals.

We all took that course some day in the past.

These tutorials are also helpful to get started with:
http://java.sun.com/docs/books/tutorial/

For your assignment above, you are at least trying to solve it yourself which is a start.

I would re-read the question details that you posted above and think about the variable "n" and where it should come from and how it is used.  Sometimes you may find it helpful when you have some mathematical or specific problems like this where they use math variables like take some number "n" and generate a value "a" and a value "b" then you may want to name your variables that in code to start with until you figure out the logic and then change to be more descriptive.  If you can visualize what these values are doing it is even better to start out descriptive variable names like intGivenNumber, intFirstRandomNumber, etc.  

Think as you work through logic, it will help you read code more like plain english (if you don't speak english, name the variables what makes sense in your language). :) Just helps IMHO.
