Android Question StringBuilder libraries

[Theera]

Refer to this ,Where can I get StringBuilder libraries for B4A,B4J,and B4i? Ithink B4Aversion13 there isn't thelibrary

StringBuilder it's a Core function.
Simply declare something like

Dim sb as StringBuilder

and it will work in B4A, B4J and B4i.
It does not need any library to be ticked.

I B4A version13 , I search the library Under the AnywhereSoftware folder. I can't find it.
There isn't StringBuilder.jar

There is no library for it.
It's included in the Core library that is always ticked as default.

Try writing something like in this image and you will find it in the suggestions.
I used "sb" as StringBuilder abbreviation, but you can declare the variable with any name you like of course.

Equivalent Core function Regex.Split works fine:
(plus note that you don't need to specify array size eg what would happen for MyTargetMoney "1.2.3" ? )

Dim MyTargetMoney As String="1234.75"

If MyTargetMoney.Contains(".") Then
    '''Dim arrNum(2) As String =sf.Split(MyTargetMoney,".")
    Dim arrNum() As String = Regex.Split("\.", MyTargetMoney)
    
    '// บาท
    strBaht  =arrNum(0)
    '// สตางค์
    strStang= arrNum(1)

    Log(strBaht & " บาท, " & strStang & " สตางค")
End If

Waiting for debugger to connect...

1234 บาท, 75 สตางค
