Hello, I have a problem and I'd like to know what causes it. I've
extracted the relevant method into a class. Basically I'd like to know
why addUserSQL outputs INSERT INTO users VALUES (null,0) instead of
INSERT INTO users VALUES (hellomum,1234567890)

The simple solution would be to move the String into the method but
there's a lot of them and it looks fairly untidy. Also I'm curious as to
what I'm doing wrong.

Code:

public class Test {

public static void main(java.lang.String[] args) {

                Test tst = new Test();
                tst.addUser("hellomum", 1234567890);
                System.out.println("addUsermain: " + tst.addUserSQL);

                }//main

                public void addUser(String username, long ipAddress) {
        //
        this.ipAddress = ipAddress;
        this.username = username;
        //**debug
        System.out.println("ipAddress = " + ipAddress);
        System.out.println("username = " + username);
        //**debug
        System.out.println("addUser: " + addUserSQL);
        //**
    }//addUser

        //attribs
        String username;
        long ipAddress;
        String addUserSQL = "INSERT INTO users VALUES (" + username +
"," + ipAddress + ")";

}//test
