Android Question Boolean XOR ("exclusive or" bit operator)

[js1234]

What is XOR boolean operator?
Like "And" "Or" …. why using "Xor" get syntax error?

Xor output is true if only one of the inputs are true

1 xor 0 = 1
0 xor 1 = 1
0 xor 0 = 0
1 xor 1 = 0

1 xor 0 = 1
0 xor 1 = 1
0 xor 0 = 0
1 xor 1 = 0

Yes Yes I know ….. but:

 Dim bTest1 As Boolean
 Dim bTest2 As Boolean

 If bTest1 And bTest2 Then
 
 End If

working OK but this is SYNTAX ERROR:

 If bTest1 Xor bTest2 Then
 
 End If

Why?

Why?

    Dim b1 As Int = 1
    Dim b2 As Int = 1
    Dim b3 As Int
    
    b3 = Bit.Xor(b1,b2)
    Log(b3)

So parameter are Int and not Boolean ... and xor is bitwise operation...

Just write a small sub to handle XOR of Booleans

'XOR:
If b1test <> b2test Then
