run java class from an activity

[Adina Haziza]

hi, I'm new in android programing. I'm still learning about activity and java class. I'm creating a program that consist splash screen(activity), javclass1 (java class contain a program that receive data from bluetooth), javclass2(java class contain program to insert string that javclass1 receive ) and MainActivity (compare data from database with editText) . I want to make my splash screen run javclass1 and javclass2 so i can run my MainActivity. can you tell me how to do it? because mostly people tell me to use intent in splash screen to main activity without running javclass1 and javclass2. thanks for your help.

What exactly do you mean by the above statement.  What is javaclass1 and javaclass2 , subclass of Activity class or something else.
