hi all (james)
i have another question: if yuh want to use the random numbers, it goes like dis: random generator = new random() or it have the math.random right my questions are
how do u get to generate the 2, 3, 4- times table,

?
hi james
what I meant is that I know random generator = new random would drop random numbers, the question is there a way that u can get to drop numbers that would be the 2 times, tables along with the rest of tables
ah know it may sound kinda weird to you and u probably thinking i am crazy
Not crazy, but I have no idea what you are talking about
hi james
it is that I am doing over the multiplication game program in java right, and it has three levels right, easy meduim and hard.
the difficult-level easy has three rounds with
4 random questions from the 2 times table- this is round 1,
4 random questions from the 3 times table - this is round 2
4 random questions from the 4 times table -this is round 3
difficult level meduim has 4 game round
3 random questions from the 5 times table - this is round 1
3 random questions from the 6 times table - this is round 2
3 random questions from the 7 times table - this is round 3
3 random questiosn from the 8 times table - this is round 4
difficult level hard has 4 games round
3 random question from the 9 times table - this is round 1
3 random questions from the 10 times table - this is round 2
3 random questions from the 11 times table - this is round 3
3 random questions from the 12 times table - this is round 4
how do i get the random generator to do exactly that. i manage to get to generate some random number to multiply, it randomly generating from the 13 and sometimes the 14 times table which is what i dont want exactly. can you guide me in the right direction as to how do get it to do exaclty dat
So all you need is to generate random ints in the range 2-12?
Create a Random and call its nextInt method as often as needed. nextInt(n) generates a number between 0 and (n-1) inclusive, so you need a tiny amount of arithmetic to get 2-n inclusive, eg
Random r = new Random();
int aNumber = r.nextInt(n-1) +2; //random number between 0 and n inclusive
thank you very much j, sometimes ah wish that i can actually see u
You would be very disappointed :)
and why would i be, let me be the judge of that j. but thanks anyway
hi j
i have tried it both ways and this is my results.
String welcomemsg, welcome="";
int count =0, user1age, user2age;
int sum_scores_user1name=0; // depend on the number of chances given
int corrans = 0, incorrans =0; // to hold all of the correct answer
int scores1 = 0; // to keep track of the scores made in the game
int wrongans =0; // to hold the number of wrong answer entered
int countlevel=0; // which level of the game the user choose to play
int passmark = 50, rand1, rand2,passmark_user1name, passmark_user2name;
int userans = 0, correct = 0;
int ans = 0, n = 2, ques = 0;
String user1name ;
String user2name;
int num1 = 0, num2 =0, ans1;

oop!! incorrect answer larissa try again
kadeem hi it is your turn
BUILD SUCCESSFUL (total time: 30 seconds)
am only getting zero right through, no other numbers are generating, why is that. tried it both ways.
Line 77 you generate one random number "number"
Then you ask the user about two completely different numbers "num1" and "num2" that you have not generated.
