I do not have idea where i can find some information to push forward this task. It is really so easy, where in help_forum is only two people asking for help, and any of them do not receive precision hints. Someone says use Bubble sort, but after that everything is mixed in my head. Someone use ArrayList and i try go this path too. For testing, I assigned 20 words rigidly so as not to slap them every time. My first idea, is to get char index "char charAt(index)" from first letter of String in tablica[] and saving it in second table_2. Sorting this using Bubble and after that match table[] to table2[]. And i realize i don't know what i'm doing... :( really.
