hi, good day, assume i have 500 records , and the records is actually the data of customer who have make transaction in a company, my question is how to i decide who are the top 5 customers who having deal with highest transaction volume in company.. anyone have idea ?
We're pleased to have you here with us on the Ranch, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.
In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
You also need to think about whether you want to deal with ties in the ranking (though in this particular case I suppose it's unlikely that two customers will have exactly the same number of transactions)
