Bug? Collection Test

    'This works fine
    Dim l As List
    l.Initialize
    l.Add(1)
    l.Add(2)
    l.Add(3)
    l.Add(4)
    l.Add(5)
    l.Add(6)
    l.Add(7)
    l.Add(8)
    l.Add(9)
    l.Add(0)
    l.RemoveAt(0)
   
    'This gives an error
    Dim l As List
    l.Initialize2(Array As String(1,2,3,4,5,6,7,8,9,0))
    l.RemoveAt(0)
   
    'This gives an error
    Dim l As List
    l = Array As String(1,2,3,4,5,6,7,8,9,0)
    l.RemoveAt(0)

    Dim m As Map
    m.Initialize
    m.Put("1", "1")
   
    'This will return null
    Log(m.Get(1))
   
    'This will log fase
    Log(m.Get("1") = 1)
   
    'This wil log true
    Log(m.Get("1") * 1 = 1)

Is this bug?

Is this bug?

No.

See the documentation: https://www.b4x.com/android/forum/pages/results/?query=list.initialize2

 

[BarryW]

How about the map

 

[Erel]

This is also not a bug. The types of the keys should be correct.

When you compare objects the types of both sides should also be correct.

It will work if you first get the value and then compare it:

Dim s As String = m.Get("1")
Log(s = 1)

 

[BarryW]

Therefore string "1" is not equal to int 1?

 

[DonManfred]

The point is that the list can not be changed in size when you define the list as an array

Note that if you pass a list to this method then both objects will share the same list,
and if you pass an array the list will be of a fixed size. Meaning that you cannot later add or remove items.

Therefore string "1" is not equal to int 1?

A string with the value of "1" will only be equal to a numeric 1 if the first operand type is known during compilation.

Dim o1 As Object = 1
Dim o2 As Object = "1"
Log(o1 = o2) 'false
Log(o1 = 1) 'true
Log(o2 = "1") 'true
Log(1 = "1") 'true
Dim s As String = o1
Log(s = 1) 'true
Dim i As Int = o1
Log(i = o2) 'true
