Hi there, I wanted to get the percentage of total vote per candidate but it always result to 0.00. Can anybody tell me what's wrong with my code?

    public static void main(String[] args) {

        //Array Declaration
        String[] candidate = {"Estrada J.", "Drilon F.", "Enrile J.", "Lacson"};
        int[] voteEs = {5, 5, 10, 11, 20, 30, 4, 15, 10, 30, 40, 50, 60};
        int[] voteDr = {10, 20, 30, 35, 25, 10, 10, 20, 30, 10, 20, 15, 30};
        int[] voteEn = {20, 15, 15, 20, 20, 30, 50, 50, 20, 10, 15, 15, 15};
        int[] voteLa = {50, 50, 10, 10, 10, 10, 10, 20 ,15, 30, 40, 40, 50};

        //Variable Declaration
        int ctr1, ctr2, totalVoteEs=0, totalVoteDr=0, totalVoteEn=0, 
                totalVoteLa=0, totalVotes;
        float percentEs, percentDr, percentEn, percentLa;
        String newPresident;
        System.out.println("************************************************"

SAMPLE OUTPUT:

percentEs = (totalVoteEs / totalVotes);

totalVoteEs and totalVotes are both ints, so this division is done using integer arithmetic. Fractions are truncated to zero, so the result is zero. You can use a simple fudge like (1.0 * totalVoteEs / totalVotes) to force the calculation into floating point, or you could re-declare your variable(s) as floating point types

:) thank you so much for helping. I re-declared my variables and it fixed the problem :D I also forgot to multiply it by 100 silly me.
