I started learning computer programming recently(about two months ago) on my own...So,i am still doing the very basic stuffs...I wanted to write a working code with what i have learnt...So,i decided to write a tic-tac-toe game(no GUI),as to that , i wrote the code bellow...The code works but it has a very big problem and I have been trying to fix it since yesterday,i couldn't.....The problem is that when there is a win,it mistakes the winner always..if Tobi and Dele are the players,when Tobi wins, it will give the win to Dele,just like that....

I know the documentation is poor (remember I am a beginner).
Help me fix this..

Wtf is this, no explanation of problem, nothing, just dropped code... Na wa o

I am really Sorry about that...was not done...just modified it.

Leave the programming world u lameass

k...like you were never once a beginner...thanks for the comment anyway.

If you know of people who can help,please give them mention ...i couldn't move forward in my learning due to this...

@OP, don't mind this one... He's prolly high on some rare stuff.

Stop using nairaland's code feature for long codes... Its crappy... really buggy... Use some other online code pasting services. BTW, where and what is the definition of the function "checkWin();" ...?

You didn't initialize turn, so it's the second player always playing first, instead of the intended first player.

The code need some refactoring, but here are the simple ones:

method checkWin should take in a parameter that holds the player who played last, so that you won't need to duplicate the if else blocks for each player

Before making a call to the checkWin method, you should test for the number of moves played, if it's not up to 5, then there is no need

Also, you could wrap the check for the non diagonal lines thus:

for (int i=0; i<=2; i++) {
for (int r =0; r<=2; r++) {
if (games[i, 0] == games[i, 1] && games[i, 0] == games[i, 2]) {
return true;
}
if (games[0, i] == games[1, i] && games[0, i] == games[2, i]) {
return true;
}
}
}

I don't know how to use any other code feature ...in fact i don't know what exactly that mean.


..modified It.... is meant to be isAWin()...I used checkWin when i wrote he code...but when i was about posting it here,I had to change the name of the boolean method so it reflect its purpose better (just to avoid insults ).

Just so you know,you inspire me a lot...though,I may not be participating in this programming section but believe me,you made me get a laptop(you made me understand even b4 learning programming that writing a working code is different from writing an efficient code ...i saw your contribution and a guy called josh to the thread about solving project euler's problems)...

CODE FIXED!...thanks a lot bro...that loop you gave is a far more concise code(took about 3minutes to understand )...Thanks...But,how good is my code on a scale of 0 to 5 ?.

You are welcome.
For a beginner, 4/5

Wow .. Thank you for the kind compliments.

This, and the apparent evidence for your passion has motivated me to go a step further with your project... So, lets attempt improve your work...

First, what JDK version are you using? ...or which IDE are you using? And what version?

I simply want to confirm whether you can use Java 8 features.

Please can anyone help me with CSS I don't know how to space objects

thanks,sir...i am using jdk1.7.

Lucasiangrey:
thanks,sir...i am using jdk1.7.

Ok. Can you install JDK1.8? You can download the Netbeans 8.2 and Java8 bundle here: http://www.oracle.com/technetwork/java/javase/downloads/jdk-netbeans-jsp-142931.html

Once you do so, buzz me.

I have installed jdk1.8 and netbeans sir.I have been using notepad ++ , i don't think i know how to use this netbeans well,yet.if it's not a necessity, i will like to just continue with the notepad ++ otherwise , i can dedicate few days to practice code and learn some features of that IDE...thanks.

As a self taught programmer, playing around the IDE shouldn't be hard...You've tried.
