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

[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.

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

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

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

[zaninheaven2]

Must have practiced first before recording the tutorial. Thanks anyway. :)

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

[MrGIZDICH]

@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.

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

ha har, thx man really helpful.

[hiro4soccer]

thanks yo X_X kinda get what to do for extend now

[JeffTheRambler]

Okay, so just to verify, in Tutorial1, the "t.ans();" or "t.liger();" call a method in the class of the object, in this case t, and then automatically run it?

[MrGIZDICH]

@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.

[JeffTheRambler]

@MrGIZDICH

No, I understood that fully, I was just wondering about the actual use of "t.methodHere();", I just wanted to verify with you that when you typed "t.whatEver();" it automatically executes that method ( With the information passed in from the parameters if it there, of course )

[MrGIZDICH]

@JeffTheRambler Yes, it will automatically execute.

[JeffTheRambler]

@MrGIZDICH

Awesome, thank you for the help.

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