write a JAVA program to read in a sequence of integers and print out the following quantities,each on a new line and in the following order,your program should be:
1) the number of integers read in.
2) the average value- which need not be an integer.注意,平均值不是实数!
3) the minimum value of the integers.
4) the maximum difference between any of the integers.
以上要求顺序不能颠倒、跪求!
