How would I execute a function by a string, and get it's return value

TheZipCreator

So like let's say I have a string, and it's set to "login", how would I call the function login() from that string. Also it needs parameters.

The function I am using is:

boolean login(String username, String password) {
  Object[] usernames = users.keys().toArray();
  boolean success = false;
  for(Object i: usernames) {
    if(i.equals(username)) {
      JSONObject user = users.getJSONObject((String)i);
      if(password.equals(user.getString("password"))) {
        success = true;
      }
    }
  }
  return success;
}

I know about method(), It's just that I can't give the function any parameters. And also I need the return value of the function too.

• As any callback function, its signature (parameters) is pre-decided. We can't change that! :(
• In case for both method() & thread(), they can only callback functions w/o any parameters. :-<
• And those functions have to belong to a PApplet subclass as well. L-)

As a workaround, why don't you try out switch () / case: instead?

boolean decideAction() {
  String action = "login", user = "name", pass = "word";

  switch (action) {
  case "login": 
    return login(user, pass);
  }

  return false;
}

boolean login(String username, String password) {
  return "name".equals(username) && "word".equals(password);
}
