Answer 1

The following is not a constructor:
public void Blackjack( String Alice, int Emily, int Matt, int Mary )
   //initializing variables in declaration
  Alice = dealer;
  Emily = player1;
  Matt = player2;
  Mary = player3;
}Remove the word "void" to make it a constructor
public Blackjack( String Alice, int Emily, int Matt, int Mary )And, your code doesn't make sense. When you make that into a constructor and run the constructor, you will do something like this:
Blackjack game = new Blackjack("Alice", 1, 2, 3);But, when you run the constructor, dealer is 'null' [default value of String variable]; and player1, player2, and player3 are 0 [default value of int variable]. Your constructor essentially says:
Alice = null;
Emily = 0;
Matt = 0;
Mary = 0;It sets the parameters to new values, but only locally within the constructor. The instance variables don't get new values at all. You need to reverse the assignments:
dealer = Alice;
player1 = Emily;
...It doesn't make a lot of sense to name your parameters to the constructor with specific persons' names. Not sure what your int values for players are for, anyway. You should have a Player class, as someone else suggested. It should have a name that can be set by the person running your program. Your game could start by saying:
What is the name of Player 1?
What is the name of Player 2?
What is the name of Player 3?Then use the names to generate messages in the program.
