B4J Question Strange error

[fishwolf]

I have this error in many case during the debug

java.lang.NumberFormatException: For input string: "23:59"

i set TimeNext = "23:59" of if TimeNext == "23:59"

if i clean the project, the error go away

NumberFormatException

Are you sure you have not declared TimeNext as "numeric" (Int, Long, ...)?

if TimeNext == "23:59"

Strangely, "==" works; where can I find a list of operators (and key words)? [Should I open a new thread for this question?]

as string, if i remove the ":" work fine

i have the similar problem with < or >, if i remove ":" work fine

i think that a string in this format it's confuse with date/time format

Dim TimeMeteo As String
Dim NameMeteo As String

   TimeMeteo = Item.Get("time")
   Log("TimeMeteo=" & TimeMeteo)
   If TimeMeteo >= "19:00" Or TimeMeteo <= "05:00" Then
     NameMeteo = "night_"
   Else
     NameMeteo = "day_"
   End If

B4i ?

You should use DateTime.GetHour(datestamp) to get the hour ( int 0-23)
