    Default Program of voting details of individual and total candidates appeared

    ok so im making this program. it lets the user enter a number of candidates, then their names, then how many votes each candidate received.

    i want the program to out put the total number of votes. how much each candidate received and who the winner is. i also want it to show what percentage of the total votes each candidate received.


    i need help with the precentage part and i also need help with the displaying part.

    below is a copy of my code . . . . in bold is the output line of code. i need help writing a long of code that has everything that i mentioned above in it.

    thanks . . .

     
    package test1;
    import javax.swing.*;
     
    public class Test1 {

    Hello and welcome to the Java Programming Forums.

    You were very close to making this code work. I have made a few changes for you:

    package test1;
    import javax.swing.*;
    public class Test1 {
     
     public static int total;
     
        public static void main(String[] args) {
     
            int winIND;
            int numCand;        //number of candidates 
            int numVotes;        //number of votes
            int best = 0;        //highest number of votes
            int voteTotal;        //total number of votes
     
            String strName = null;        //name of candidate
            String strNumVote;    //number of votes for each candidate
            String strNumCand;    // get the number of candidates from user
     
            //get the number of candidates
            strNumCand = JOptionPane.showInputDialog("Please Enter Number of Candidates: ");
            numCand = Integer.parseInt(strNumCand);
     
            int votes[] = new int[numCand];
     
            for (int i=0; i<numCand; i++) {
     
                strName = JOptionPane.showInputDialog("Enter Name of Candidate: ");
                strNumVote = JOptionPane.showInputDialog("Please enter total number of votes: ");
     
                votes[i] = Integer.parseInt(strNumVote);
     
                total = total + votes[i];
     
                if (votes[i] > best)
     
                best = votes[i];
             }
     
           total = sumVotes(votes);
           int k = winIndex(votes);
     
            JOptionPane.showMessageDialog(null, "Total votes: " + total + " and the winner is: " + strName + " with " + best + " votes.");
     
        }
     
     
        public static int sumVotes(int a[]) {
     
         int sum = 0;
            for (int j = 0; j<a.length; j++)
             {
                 sum += a[j];
            }
                 return sum;
        }
     
        public static int winIndex(int votes[]) {
     
            int winIND = 0;
                for(int i = 0; i<votes.length; i++)
                {
                    if(votes[i]>votes[winIND]);
                        winIND = i;
                }
     
            return winIND;
     
        }
    }

    You cannot have strName[k] because you have not assigned strName as an array.

    This displays total number of votes, who the winner is and how many votes they received.

    If you want to display each candidate and also show their percentage then you are going to have to work this into a for loop:

    JOptionPane.showMessageDialog(null, "Total votes: " + total + " and the winner is: " + strName + " with " + best + " votes.");
