hi
I am trying to build this game. what i have been trying to build for a long time now. it is a multiplication java game that need random numbers to generate
it goes like this
difficulty level-easy: this difficulty level easy has 3 rounds. the student must be tested on 4 random question from the 2 times table (round 1) 4 random question from the 3 times table (round 2) and 4 random question from the 4 times table(round3) every time the game is launched it must generate different random questons for each round.
here it what i have so far but it is not the correct because it is generation something different

        String welcomemsg;
        int count =0;
        int timestable, user1age, user2age;
        int chances=0; // depend on the number of chances given
        int corrans = 0; // to hold all of the correct answer
        int scores = 0; // to keep track of the scores made in the game
        int wrongans =0; // to hold the number of wrong answer entered
        int count_leveleasy = 0; // which level of the game the user choose to play
        int count_levelmedium =0; // which level of the game the user choose to play
        int count_levelhard = 0; // which level of the game the user choose to play
        int passmark = 50;
        int userans =0, correct = 0;
        int product =0, random1= 0, random2 = 0, problem =1;
        String choice;
        int b1value = 0,d1value = 0;
        int ans;

BUILD SUCCESSFUL (total time: 22 seconds)

? That reads the wrong way round...
If you do not set a seed then the Random() constructor picks one - eg current time in mSec - so two runs will provide different sequences.
If you set a seed and it's the the same, then you will get the same sequence.
