奇怪的Integer.parseInt异常(Strange Integer.parseInt exception)

奇怪的Integer.parseInt异常(Strange Integer.parseInt exception)

线程“Thread-2”中的异常java.lang.NumberFormatException：对于输入字符串：“3”

int test = Integer.parseInt(result[0]);

当我尝试将“3”转换为整数时，这是我不断得到的错误。 好吧，我通过RS-232端口收到这个“3”，所以也许这就是造成错误的原因。

如果有人知道可能导致这种情况的原因，我们将不胜感激。

Exception in thread "Thread-2" java.lang.NumberFormatException: For input string: "3"

int test = Integer.parseInt(result[0]);

This is the error I keep getting when I'm trying to convert "3" to an integer. Well I'm receiving this "3" through a RS-232 port, so maybe this is what is causing the error.

If anybody has any idea what could be causing this it would be appreciated.

结果[0]的数据类型是什么？ 如果它是一个字符串，你确定它周围没有空格或新行吗？

试试result[0].trim()

What is the data type of result[0]? If it's a string, are you sure there are no spaces or new lines around it?

Try result[0].trim()
