Discuss creating and Using Objects 

//we can use code below to create a object with a subclass called Writer.

Writer mywriter = new Writer(); //creating an object call mywriter.

//and using the object like give him an order

mywriter.write(); // mywriter(objectname).write(methodname in the subclass)();

Discuss extends 

//extends like: a subclass "extends" the super class, the subclass can inherits its attributes and behaviors from the super class 
//If we want to create a subclass extends a super class we can use the code below

public class Writer extends Jobs {
    
    public Writter(){   //constructor
        super()         //"super" means the method(attributes and behaviors) in the super class "Jobs" is also access to the subclass "Writer"
    }
    
}

In code.org unit 1 lesson 14, I tried to test the code below but found an error: "There is no more paint in the painter's bucket"; so I can't even start to draw the pattern. 

myPatternPainter.paintPattern("white");
