Question

For the following activity, you will submit your entire program to the code runner, from your first import statement to your last curly bracket.

Please download the Lesson 35 Activity template (Links to an external site.) and use it to write your code. Additionally, you can download the Lesson 35 Coding Activity (PDF) (Links to an external site.) to print or use as an offline reference.

If you need a refresher on how to use this Code Runner, watch the video in the Submitting Code and Formatting FAQs page in the Course Introduction.

NOTICE: Code runner requires a complete program. Please download the template and pdf (Links to an external site.) and use the template to write your program in DrJava. When you have finished your program, copy its entire contents, from the first import to the last curly bracket, into the code runner below.

Discussion Questions

With your class, answer the following discussion questions:

What overloaded methods have we seen in this class? Think about methods on Strings, methods in the Math class, System.out methods.

Read the String documentation (Links to an external site.) and see if you can find any more overloaded methods. Can you find any overloaded methods that have not been mentioned in class?

Write four overloaded methods called randomize. Each method will return a random number based on the parameters that it receives:

• randomize() - Returns a random int between min and max inclusive. Must have two int parameters.
• randomize() - Returns a random int between 0 and max inclusive. Must have one int parameter.
• randomize() - Returns a random double between min and max. Must have two double parameters.
• randomize() - Returns a random double between 0 and max. Must have one double parameter.

Because these methods are overloaded, they should be declared in the same class, so there is only one code-runner to test all four methods.

Answer 1

Thanks for the question, here are the 4 overloaded methods() declared inside a class. I named in Randomize.java you can update the class name to any name you like.

Here is the complete code.

=======================================================================

import java.util.Random;

public class Randomize {

    private static Random random = new Random();

    public static int randomize(int min, int max) {

        return min + random.nextInt(max - min + 1);

    }

    public static int randomize(int max) {

        return randomize(0, max);

    }

    public static double randomize(double min, double max) {

        return min + random.nextDouble() * (max - min);

    }

    public static double randomize(double max) {

        return randomize(0,max);
    }


}
