the qestion is
Implement a java project to help in the study analysis with the following steps:
• Read from the user the number of cities (minimum 6 cities.)
•For each city: city name and the number of persons (minimum 10 persons) are entered.
• For each person in a city: mass and height should be entered, BMI and BMI category have to be computed and printed.
• For each city, the number of persons and percent ratio in each BMI category should be computed and printed.
• Finally, the program should print a summary report with the following details: o Number of cities. o Total number of persons and percent ratio of persons in each BMI category in all cities. o The name of the best city which has the maximum percent of persons in normal weight BMI category and these people’s percent ratio. o The name of the worst city which has the maximum percent of persons in obese BMI category and these people’s percent ratio. o The name of the city which has the minimum percent of persons in underweight BMI category and these people’s percent ratio.

ps: should not apply arrays in this program and must be simple

The instructions are almost pseudo-code for the actual solution. Each sentence represents a few lines of code, all in the right order.
So start with "Read from the user the number of cities " and code that, then go on to the next line.
