Is that the exact line? The arguments obviously need no data type. What's the name of the class that method belongs to?

It looks as if your calling a non-static method statically. So you want to either make an instance reference and call your method that way or make the method static.

You don't include the parameter types in a method call. Remove them and only pass the variables by themselves:

Store.changeLoanStatus(bookname, authorf, authors);

Then on the same line "Store.changeLoanStatus(bookname, authorf, authors); a new error has appeared - - - - "non-static method changeLoanStatus(java.lang.String,java.lang.String,java.lang.String) cannot be referenced from a static context ? :S ?
