Passing Parameter between Methods

Question

I have some problems because i don't really know how to pass parameter between methods in a java class.
How can i do that? below is the code that i did.
I want to pass in the parameter from a method called dbTest where this method will run StringTokenizer to capture the input from a text file then it will run storeData method whereby later it will then store into the database.
How can i pass data between this two methods whereby i want to read from text file then take the value to be passed into the database to be stored?
Thanks alot

In a nutshell, you don't "pass" parameters. You simply call methods with whatever parameters they take. So, methods can call methods, which can call other methods, using the parameters in question. Hope that makes sense.
