Okay in Java we can create a class and the object so let's say I want to create a class here new directory here I'm gonna put a new Java class there let's say I want to create a class called new class or less he I Korea essay maybe Ah, some book okay and I finish okay then okay inside this is the class and then inside this class I can pull something like private, ah maybe private string then the waste property, maybe the book These are color okay then private. Say you can the size maybe the Boolean is easy there's a small okay. And this is the property of these a these book then I can create some of the gainsay. Meta Okay. Let me find the is a part time or in replace construct in the span transform effect run only to be some format ah compare coins spray skin changes say in circle or concrete coat is I want to insert I say get okay and I also want to insert these set the key for myself by usually typing all these meta myself by NetBeans hours.

Some shortcut here you can use to generate some code here. So, this is the get and set method, the models are get set properties then we have some method as a povery work and but do maybe a public void say ah call maybe yeah poor call and then I say System dot out dot green lie chip chip chip okay. So this is the action or this is what the book can do. This is the property property of the book. This is why the book can do. kV can also at least one more important one is the constructor close to the povery but so our constructor will be empty for now Okay, I saved these cross then if I want to use these, but crossing these main meta I can do something like this.

So let's see. But yeah give the class here on named I see I gave above As a pigeon t equals new but okay pigeon dot call okay I ran this code and as you see okay what this means is that this is the bulk cross okay I then I use these bulk cross to create an object called pigeon key and then I call these ladies pigeon called meta k call this meta comet so this patient object I will say you care access to this book class here access to this letter in the class is called the touch Scottie cometa and your printer turtle chip okay. So this is roughly how this class and this object works okay if I want to specify the color of the book I can do something like this pigeon though sec yeah these settler here sec Hello Alessia PJ that P is black.

Okay then pgn.is I cannot say they call these is more I have to use settings more. settings to true. Okay then if I want to print the patient color, I can do something like this system dot o dot brain. ly. k. pigeon da. Get color System dot out dot print ly the journey, though.

Yeah, he's small. Yeah, I can do something like this. Okay then I will. I will run ad to run this code and then we'll show right and then the true okay. So what this mean is for these this line here so but Easter cross crosses like we usually say subgrouping So, we use these bullet cross we use these on blueprint to create this page object. Okay then in this page object we set the color to black and then in this page and Jeremy saga is small variable to true.

Then we print out the color variable and then we print out the small variable values. Okay, as I previously mentioned before, this private modifier he means These variables can only be accessed within this class. So, when we call these use these Pugin object, we cannot straight away gather color, we can only get a color variable, we have to use this set color method to change the color variable values. So, this set color method using this public modifier. So, appropriate modifier means that we can access this method or this variable or this class in any class. So, private variable we can only access these variables within the same class.

Okay. So, I see you use a book cross quiz A pigeon object. Then, from the pigeon object, we set a color. From the patient object we set a small variable. There we print out a color, we print out a small variable and use, then we let a patient object call using these comments here. So this is roughly how we use our class and object in these Java programming.
