计算输入值？ [英] Count input values?
问题描述
我正在尝试编写一个读取未指定数量的正值和负值的程序，对它们进行计数并计算输入值的平均值，而不是计算零。程序应以输入0结束，并将平均值显示为浮点数。
我可以使用什么来计算输入值？
示例：如果我输入1,2和0，则平均值应为1.5
Ps：我是初学者...
I''m trying to write a program that reads unspecified number of positive and negative values, counts them and computes the average of the input values, not counting zeros. The program should end with the input 0 and display the average as a floating point number.
What can I use to count the input values?
Example: If I type 1, 2 and 0 the average should be 1.5
Ps: I''m a beginner...

了解Scanner类（用于读取输入）并尝试该程序。你应该使用while循环。
如果你遇到代码就发布。
Read about the Scanner class (for reading the input) and try the program. You should make use of a while loop.
Post if you get stuck with the code.

是的我知道如何读取输入，但我如何计算？
Yes I know how to read the input, but how do I count it ?

你如何在现实生活中统计它们？考虑一下，然后你会找到答案。
PS：你有没有发现，如果这个数字是正数还是负数？那是当然的第一步。
问候，

How would you count them in real life? Think about that, then you''ll find the answer.
PS.: Have you found out yet, if the number is positive or negative? That''s the first step of course.
