Java Tutorial 13 - Inheritance (Superclass, Subclass, & extends)

In this tutorial, you'll learn how to use superclass and subclass and the purpose of it. You will also learn a new keyword/syntax called "extends."

This actually really helped me out. I would probably be monotone too talking to my friggin computer. Just deal with it and follow along. Its a good tutorial

Much easier to learn this way than from the book. It's easier than I thought.

This is good. Makes sense. Thanks for putting it up!

I learned a very good example of Inheritance in Java class at college. It's very interesting

[snewmy]

Tutorials are great. Simple and gets right to the point. Thanks for making them!

@JeffTheRambler You are correct. Tutorial2 is basically the extension of tutorial3. It's like those two classes are combined into one class, but it's really not. I hope I didn't cause any confusion.

I got it and ive been learning java for 4 weeks now so i think you did a good job. I would like to see you using eclipse though ... but thats just a personal preference it doesnt matter :)

@L8JLMnky Those two keywords are used when you have a global and a local variable that are identical. Those two keywords prevents shadowing/confusion to the program. I have two video tutorials over those two keywords if you want a detailed explanation.

[JohnGizdich]

@JeffTheRambler Yes, it will automatically execute.

[JohnGizdich]

@m4712ix Sorry about that. I might redo this tutorial soon...

[WennieBoy]

Thanks man, It's better to watch YouTube tutorials than to read eBooks :)

[juliolopez]

Naw, dude. That was pretty awesome. Thanks!

[hirosoccer]

thanks yo X_X kinda get what to do for extend now

[cdowns]

this is helpful and all but dude you really should consider getting an IDE like Eclipse or JCreator or something

[alabhyadahal]

whats the difference in using multiple method and using inheritance ??

[Traceguy]

oh, saying "javac Tutorial1.java" will compile all .java files accociated with it. So it will also compile 2 and 3. You could also say "javac *.java" and compile all java files in the directory.

son of a BISCUIT. This is a prime example of why developers shouldn't be teachers.

[JohnGizdich]

lol This made me laugh. The reason my voice sound "retarded" is I wasn't a big public speaker at the time. I also wasn't used to talk much in front of the computer screen, and that is most likely why it sounds like that.

[LJLMnky]

When do you use the reserved word *super* or *this*

[Grummpyro]

I love your tutorials but it seems like ur sleep making tutorials.
