Learn Programming in Java - Lesson 07 : JavaDoc and Unit Tests

In this lesson we continue our exploration of objects and classes. We'll learn how to use the JavaDoc comment syntax to document our class methods as we implement a class which simulates playing cards. We'll also introduce automated or unit testing - focusing on how it can be used to help you reduce the semantic errors in your code.

Wow, simply the one the best and extremely easy to understand. Well Done Michael, and thank you!

With every new episode things get better and better.
Thank you, Mike! You're true hero for us!

I wanted to thank you for putting this together, a lot of hard work. I graduated w a C.S. degree from the University of Washington in 2010, didn't really do any of this for the last few years, and this is great. putting in the debugging exercises, the Java docs info, and unit testing makes this much better - we did almost none of that. great work!

Your videos are so much more informative than my classes at uni, where the lecturer literally just reads straight from the textbook in a drone voice and gets annoyed if you ask questions... Thanks for the videos, Cheers

Dear Sir Fudge your videos are very efficent and clear to understand.Thank you for these videos.

[josueluna]

Things are slowly but surely starting to click. I'm getting there, thanks Fudge.

I had to pause the video to take a moment to say this " Just kidding . Love you man you are the best!

Can someone help me please? I can"t seem to get the desired output if I use the Override method. I get the following error : Exception in thread "main" String index out of range: 12

I typed the exact same code as the one in the tutorial.

I dont get unicode to work. Always displayed "?". Any advice where to look?

Hi there. Thank you sooo much. i have watched up to this video over the past 3/4 days and ive learned more from them than my class at uni (that ive been in for over a month).


only issue i have is with the testing part of this video. When i use it it says BUILD FAILED (total time: 0 seconds). is there any way around this?

[OneWorld]

I am having real hard time her... I am using eclipse and for past 3 Days I am trying different options so that test methods : TestSameRank, TestSameSuit etc are filled as yours. Are they really autofilled (21:05) or you code them yourself. Becuase in my methods only one line appears and that is "fail("not yet implemented")".... What am I doing wrong?

[ItsNom]

Does anyone know how to write a method where you pass in the card as suit and rank and have the cardno returned?

[n.g.]

Whenever I try to print a card, the unicode symbol is a question mark. Does anyone know why? Is the video out dated?

[geckosports]

hello sir, why there is an error in my statement " return rank.charAt(this.ranks)" - that says incompatible types char cannot be converted to string..Hoping for your answer.thanks

[smithcodes]

Hello Michael ! Please help me, whenever i try to run javadoc, the IDE says " Cannot perform javadoc here" at the bottom of the screen, what to do ??

[michaelfudge]

public classes are accessible but you must still import them.

[sriharisridhar]

My age is 16, I am quite interested in java and i love your tutorials.. But in school, they are teaching C++ . So, is there a chance that I may get confused between the 2 codes?

[sriharisridhar]

Fudge sir, I can't understand the mathematical function applied here.

[aashirkhan]

@13:00 you say 13/13 =1 and 1%4 is 1? How is the second one true? If you divide 1 by 4 how is the remainder 1?

[theodule]

Michael, You are just incredible! I was struggling to understand OOP but you made it so easy for me! Receive all my gratitude! Keep it up brother!
