How to make calling a Method as a background process in java

How to make calling a Method as a background process in java

In my application , I have this logic when the user logins , it will call
the below method , with all the symbols the user owns .
public void sendSymbol(String commaDelimitedSymbols) {
try {
// further logic
} catch (Throwable t) {
}
}
my question is that as this task of sending symbols can be completed
slowly but must be completed , so is there anyway i can make this as a
background task ??
Is this possible ??
please share your views .
