VBA/VB was the best solution to customize the ArcGIS and extensions since ESRI has dropped the VB environment and most rely on Python, which is integrated in ArcGIS package itself, you can also use other coding languages too to develope ArcGIS and its extensions.
ArcGIS supports Java
But most of my colleagues use Python, a lot
And I would suggest to start there
Python is a programming language that resides inside ArcGIS, ArcMap and other related
But if you are referring to App extensions, then it is in java (with or without Python)
Hope this helped
