NumberFormatException：对于输入字符串：“8:00”

Question

那么这有什么问题？ 它给了我这个错误

Exception in thread "main" java.lang.NumberFormatException: For input string: "8:00" 
    at java.lang.NumberFormatException.forInputString(Unknown Source) 
    at java.lang.Integer.parseInt(Unknown Source) 
    at java.lang.Integer.parseInt(Unknown Source) 
    at payroll.main(payroll.java:49) 

这里是我的代码：

你" : "是分割字符串和您的时间字符串是8:00，分裂就应该像":"只是删除空格。因此，而不是tmpTime = strTemp.split(" : ");，请尝试其为：tmpTime = strTemp.split(":");
