How to Disable Random Numbers in Java

Java includes a class that generates random numbers. You use this function to disable random numbered selections — useful for games or functions in which you want to randomly show the user a record, such as a predictive dialer for a customer service application. You use the random-number-generator class to pass to the function that disables your Java controls.

Instructions

1. Open your Java programming editor and open the Java app project you want to edit. Open the source code file you want to use to create the random number.

2. Initialize the random generator class. Initialization lets you set up the generator to return a number. Add the following code to the file:

   Random random = new Random();

3. Generate a number. You specify the range in which you want to generate a number. The range is from zero to a positive integer number. For instance, the following code generates a number between zero and five:

   int number = random.nextInt(5);

4. Pass the integer to the function that disables the control. For instance, the following code passes the random number to the "DisableControl" function:

   DisableControl(5);
