                  问题描述

                  Java代码如下:

                  String s = "0.01";
                  int i = Integer.parseInt(s);
                  

                  但是这会引发 NumberFormatException... 可能出了什么问题?

                  However this is throwing a NumberFormatException... What could be going wrong?

                  推荐答案

                  0.01 不是整数(整数),所以你当然不能把它解析为一.请改用 Double.parseDouble 或 Float.parseFloat.

                  0.01 is not an integer (whole number), so you of course can't parse it as one. Use Double.parseDouble or Float.parseFloat instead.
