Android Question why this string raise an error on split

[Addo]

i am trying to split this string

14~106~GC2~~700~0~~

using the following code

Dim paramstr() As String = Regex.Split("\~", "14~106~GC2~~700~0~~")

For i = 0 To paramstr.Length
Log(paramstr(i))
Next

i got this arrayindexoutofbound error

java.lang.ArrayIndexOutOfBoundsException: length=6; index=6

any idea why ?

For i = 0 To paramstr.Length - 1
You must use paramstr.Length - 1 because the index begins with 0.

 

[Addo]

this should have a Length of 6 if i use paramstr(6) it raises the error

 

[Erel]

because the index begins with 0.

this should have a Length of 6 if i use paramstr(6) it raises the error

    Dim paramstr() As String = Regex.Split("\~", "14~106~GC2~~700~0~~")
    For i = 0 To paramstr.Length-1
        Log($"Par #${i}:${paramstr(i)}"$)
    Next

results in

Par #0:14
Par #1:106
Par #2:GC2
Par #3:
Par #4:700
Par #5:0

It HAS 6 entries. You need to remember that the index starts with 0 as mentioned two times now.

The 6th Item has Index 5

Hi PassionDEV,

It happens if you are coming from another language.
Though the .length gives actual length which matches with other languages, but the index starts from 0 so you will have to check up to .length-1.
