How can I locate and print the index of a max value in an array?

Question

For my project, I need to make a program that takes 10 numbers as input and displays the mode of these numbers. The program should use two arrays and a method that takes arr

Answer 1

Your mistake is in comparing if ((newnumber > modetracker[i-1]). You should check if the newnumber is bigger then the already found max. That is if ((newnumber > modetracker[maxIndex])

You should change your last rows to:

    int maxIndex = 0;
    for (int i = 1; i < modetracker.length; i++) {
        int newnumber = modetracker[i];
        if ((newnumber > modetracker[maxIndex])) {
            maxIndex = i;
        }
    }
    System.out.println(maxIndex);

Answer 2

You could change last part to:

int maxIndex = 0;
for (int i = 0; i < modetracker.length; i++) {
    if (modetracker[i] > max) {
        max = modetracker[i];
        maxIndex = i;
    }
}
System.out.println(maxIndex);
