Lesson 2 Lab Assignment - Java: Random Behavior

What Will You Learn

Use of more sophisticated methods

Use of random numbers

Contents

Using the classes from Lab 1, app and student, create a solution for implementing some kind of random behavior for your student. Suppose the student can be reading, surfing the web, or interacting with other students. You will need to check now and then to see what the student is doing. You will be asking the instance of the student class and what it is doing at certain time intervals.

You Will Need To:

Create a method in the class student that returns what the student is doing.

Have this method generate the behavior randomly. It cant return the same thing every time.

Implement a for loop in the application to call for the student behavior 20 times.

In a 20 minute period, you are going to check once a minute = 20 times.

Give a total count for each activity.

Calculate and display the percentage, of the twenty behaviors displayed, spent on each activity.

NOTES:

Do not add any new attributes or variables to the student class.

The only change to the student class should be the addition of the method.

No need to work with TIME functions in Java. We are making a simulation as if every count of the for loop is one minute.

Generate a report in the end summarizing what the student did in class.

Example:

John is reading

John is reading

..

John is interacting with peers

John is surfing

Suggestions

If you need some help, see below for some suggestions:

My suggestion below is a step-by-step solution. Try to implement each step, one at a time.

Start with one of the examples from lesson 01. The new method whatsUp() is one more method in the student class. The student class should still have everything as before (first name, etc, getName() methods, same constructor).

Create a method called whatsUp( ) in the student class. This method is going to return what the student is doing in class. At first, make it return always the same thing, a string for instance, surfing the web." Later, I will suggest how to return different things.

Change the app. Include a for loop, such as:

for (int j = 0; j

If you made it here and read my example with random numbers above, try to change the whatsUp method so that it returns different behaviors randomly.

Use integer variables to count the number of times each activity occurs.

Use float variables to calculate the percentage.
