B4J Question Save data in a txt-file

[Orejana]

I'm quite new to coding and I have never worked with saving stuff into an external file before.
I want to save multiple things to one line, e.g. temperature and date, "32", "08/06/18" or similar to that. I can't seem to figure out which text file method to use, can someone help me please? Thanks a lot!

Hi, use SQLITE.

maybe like this

temp="32"
time="08/06/18"
save("log.Text",temp&","&time)

Sub save(namefile As String,value As String)
    File.WriteString(File.DirTemp,namefile,value)
End Sub

temp="32"
time="08/06/18"

Sub save(namefile As String,value As String)
    File.WriteString(File.DirTemp,namefile,value)
End Sub

Thanks for your replies!
I tried it like this, but didn't know how to retrieve this data separately lateron. Any tipps for that?

open("log.txt")
Sub open(namefile As String)
    Dim x As String
    x=File.ReadString(File.DirTemp,namefile)
    temp=x.SubString2(0,1)
    time=x.SubString(3)
End Sub

Why does it need to be a text file?

You can use StringUtils.LoadCSV / SaveCSV to create CSV files.

It actually doesn't, thanks for that tip :-D
Saving works fine now, but if I want to log the loaded CSV, I only get: (ArrayList) [[Ljava.lang.String;@408efbe8, [Ljava.lang.String;@5ad11920, [Ljava.lang.String;@78285dd6]
What did I do wrong?

    table2 = su.LoadCSV(File.DirApp, "2.csv", ",")
   Log(table2)

For Each Row() As String In table2
 Log(Row(0))
Next
