这是我到目前为止所写的,我不知道从哪里开始:

public double findPercentageGreaterThanTwenty(int[] intArray) {
    double average = 0;
    for (int i = 0; i < intArray.length; i++) {
        sum = i;
        if (intArray[i] > 20) {
            average = (average + intArray[i]) / sum;
        }
    }
    return average;
}
