没有小数点的计算器 [英] Calculator without a decimal point

这最初只是一个没有小数点的计算器。添加小数后，它现在告诉我无效的第二个数字。

This was originally just a calculator without a decimal point. After I added the decimal, it now tells me invalid second number.

推荐答案

对不起德克萨斯州的迟到回复。您以前处理的是整数（没有小数点）。

要捕获整数，使用Integer.parseInt就足够了。添加小数点时，Integer.parseInt不再足够。您现在需要Double.parseDouble并将变量从int类型更改为double类型。我在下面做了这些更改。

Sorry Texas for the late reply. You were previously dealing with integers(without the decimal point).
To capture integers Integer.parseInt was used which was adequate. When you added the decimal point, Integer.parseInt was no longer sufficient. You now need Double.parseDouble and change your variables from int type to double type. I have made these changes below.
