Learn Programming in Java - Lesson 08 : If-Else statement

We'll introduce the if-else statement in this lesson. First we will cover how the statement is used to branch the execution of your code. Next we'll code an example which places bounds on user input. We'll finish this episode utilizing everything we've learned so far to create a program to simulate player-monster combat in a dungeon hack style game.

so glad the vidoes are back, I made it this far and your videos have been so helpful

Thanks Michael. Finally I have found the tutorials that match with my learning style.

You know, in every tutorial I have read and listened, only in your tutorial I notice that I am learning.

[FaithBiete]

great video, learn a lot from you. Thank you for posting

[raziuddinmohd]

thanks, Michael sir! your explanations are awesome...

[johnsonmrbear]

Thanks for your tutorial. Just want you know that in solution of challenge activity 3. When it is turn for the monster, the if condition should be "if (roll >= player.armorClass()) " but not "if (roll >= monster.armorClass())" anymore. Again, thanks for your tutorial. Learnt a lot from them.

Hey Michael,  gr8 videos, but I am bit confused in the Actor's Class there is a weapn() method which is imported from a Weapons Class. I can tell that it returns a type Weapon, but still unable to build the class and methods myself so could you explain this lesson, it would be better than to get the code from gitHub.

Hi, I'm new to java, as in I've just made the "Hello World" code a few days ago. (I have done batch files before so I understand the basics of variables and such) I'm trying to ask someone to input their favorite color (red or blue) and then have an if statement so that if its red, its set a variable to red, and if its else, than it sets the variable to blue. But I get an error saying that I cannot convert a string to boolean. I've tried using 1 or 2 as an int instead of red or blue but I get the same error only with and int. Can anyone help me?

So far I am following every step you take in every lesson, but it is not clear to me where I can get the classes/packages for the Dungeon Hack in this if-else lesson.

The player.weapon().action() was confusing at first but it makes sense now. The player.weapon() is in the Actor class and returns the weapon, and then the .action() method is now applied to the weapon using the Weapon class.

Thank you for the helpful videos.
Can you please help to explain the following:
In Weapons Class, Constructor Method, what is happening with this statement --
this._die = new Die(_maxDamage);

[igihara]

too bad you didn't make the whole video on every class (for us beginners).. this way is much more interesting to learn..

[sufiyansiddiqui]

Sir i understand if else
But i find difficulty in actor class

[shubhamrawat]

Can someone tell me how to get the source code of above program??

[williamallen]

Can anyone teach me on how to download javascript from Github?
I tried to download but it doesn't work for me

[karolinaburzova]

Hi Michael! I like your programming tutorial, it´s really helpfull! And I have One question: how can I do that a monster will remember his decreasing health between executing the run program?
I don´t know how or where to download the source code, so I wrote Actor and Weapon class by myself and it works but I can´t kill the monter :D
Thank you!

[jaysky]

Is it wise to use a method name() or it is better to use getName()?

[exuviaprime]

Why using die class? I think you can just use a random generator and set it from 0 to 20 for rolling a dice instead of making a class with value sides and blah blah

if (finalGrade >=Grade.A.Min()) {
finalLetter = Grade.A;
} else if (finalGrade >=Grade.B.Min()) {
finalLetter = Grade.B;
} else if (finalGrade >=Grade.C.Min()) {
finalLetter = Grade.C;
} else if (finalGrade >=Grade.D.Min() ) {
finalLetter = Grade.D;
} else {
finalLetter = Grade.F;
}

here some one should explain the working of Grade.A.Min()(ie.how this class name.A.functionName).
i mean why cant we declare an object of grade and call the min();
