Object Oriented_2-9 Programming Exercises

Define a worker class Worker, which has five attributes of name, gender, age, occupation, and mode of transportation, two methods, job and work, instantiate the class, get a worker object $workerone, call the method inside the class job, and then Instantiate a worker object $workertwo, modify the name, age, gender and position through $workertwo, use $wokertwo to call the job method, and the running effect is as follows:

 

Task

 

1. Define the worker class Worker 

2. Define the five attributes and methods of the subject requirements

3. The content of the red box in the rendering must be obtained by calling the work method

4. Instantiate the first object and call the job method

5. Instantiate the second object, modify the properties, and call the job method.

// Modify properties
