I think a better way to do this is to create a user info class to store the information of a particular user like this.
// I made them all public but this might not be a good idea!
class UserInfo {
String user;
String pass;
String secretCode;
}
And you put it into an ArrayList.
ArrayList <UserInfo> InfoList = new ArrayList<UserInfo> ();
Then for your current methods, you can do
// Not so sure what you want to do in this method... so you get to figure out that yourself!
public void userInternalDatabase (UserInfo info) {
this.user = info.user;
this.pass = info.pass;
this.secretCode = info.secretCode;
}
public void addUser(String i, String j, String k) {
UserInfo newUser = new UserInfo();
newUser.user = i;
newUser.pass = j;
newUser.secretCode = k;
InfoList.add(newUser);
}
public Object findUsername(String a)
{
for (int i=0; i <InfoList.size(); i++) {
if (InfoList.get(i).user.equals(a)){
return "This user already exists in our database.";
}
}
return "User is not founded."; // no Customer found with this ID; maybe throw an exception
}
