Android Question [Custom Class] is it possible to set isInitilized to False if a condition is not met?

So.... Is it possible to return isInitialized as False or to "Un-Initialize" my class?

I would implement my own “isInitialized” function.

java.lang.RuntimeException: Class instance was not initialized (.....)

Something like (B4J but should work in B4A too)

B4X:

Sub Process_Globals
    Dim k As myClass
End Sub

Sub AppStart (Args() As String)
    k.Initialize(4,"init")
    Log(k.isInitialized)  ' returns true
    k.Initialize(5,"fred")
    Log(k.isinitialized) ' returns false
End Sub

myClass

B4X:

Sub Class_Globals
    Dim isInitialized As Boolean
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize( a As Int, b As String)
    If b <> "init" Then
        isInitialized = False
    Else
        isInitialized = True
    End If
End Sub

The object will still be created - you need to rely on isInitialized to know if its usable

Only as far as B4J is concerned, for java it will still be tied to the
Dim thing As MyClass

safer to add this line then you know GC will remove from memory
if thing.isInitialized = false then thing=null
