問題2.計算統計
編寫一個Java程序Statistics.java來提示用戶輸入一些正實數並存儲
提示
輸入一些正實數
它們放在雙精度類型數組x [10]中。 用戶最多可以輸入10個數字。 該程序
它們放在雙精度類型數組x [10]中
當用戶輸入第10個數字或輸入一個負值（例如， -1。
然後，程序開始計算以下統計信息。
1.總和= ∑𝑥𝑖
𝑛
𝑖= 1
2.均值，𝑥̅=
𝑆𝑢𝑚
𝑛
3.最大值
4.最低
5.標準偏差，𝜎 =√
∑
𝑛（𝑥𝑖−𝑥̅）2
𝑖= 1
𝑛−1
（僅適用於n> 1）
使用以下五個數字測試您的程序，分別為1.23、2.05、4.0、0.01、0.12。 他們的總和= 7.41
平均值= 1.48，最大值= 4.0，最小值= 0.01，標準偏差= 1.64。
