I'm sorry but I have problem with my FarmGame again :((( in this case, my game must can inputting data to file formated .txt and can show that if we choose the "Look our Plants" list.
I tried so many times and exactly it doesn't work at all :((
So, before we want to buy, sell or show our plants, we must walk to garden first, when we touch the garden it would showing us 3 lists,
1. Buy Plants;
2. Sell Plants;
3. Look our Plants;
when we choose the 1st list, so it would be go to the BuyPlants World that show us 3 lists of Plants (Grape, Guava, and Manggo) wich have a sell price. when we wan't to buy the Plants, I make a 3 buy button for the Plants, we concern to the buy button in Grape (Button4)..
I tried to code and I just have the code like this..
There's no error when compiling that code.. but when I tried to click the button, this is no act :(( there's no ChaChing sound and also the code like useless.. :(( I don't know where's the problem...
After that, I tried to code for the 3rd list.. (Look our Plants)
I tried to code like this in (List3.class)
But.. it has an error that shows unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown in this code...
I don't know what must I do then :(( I tried to code this in 2 days and I don't know It's right or wrong because It doen's work in my game ;))
If you have a suggest or know what's wrong with my code.. please reply this.. your help is very very meaningfull for me ;))
