How to set multiple conditions on actionPerformed

Question

I am making a game of Connect 4 for a school project and have come across a problem..
Basically I am trying to get a piece of code to be executed when one of seven buttons have been clicked, (each button also has another piece of code depending on which button is pressed) Here is a sample of what I have tried
public void actionPerformed(ActionEvent event)
     //Get command of the button pressed
     String command = event.getActionCommand();
if (command == "One")
          //Code that will be executed will be here
if (command == "Two")
          //Code that will be executed will be here
     }etc for each of the seven buttons... NB: Everything above this works fine, its the next part that is the troubleif (command == "One" | "Two" | "Three" | "Four" | "Five" | "Six" | "Seven")
               //Code that will be executed will be here
}I have also tried it with two || ...
if (command == "One" || "Two" || "Three" || "Four" || "Five" || "Six" || "Seven")just in case
Thanks for any help I appreciate it

1) Do not compare Strings with "==". Use the equals( ) method.
2) When doing boolean comparisons, you need compare complete statements against each other. In other words it's something like so:
if (a == b || a == c || a == d || a == e)
}or with Strings
if (a.equals("b") || a.equals("c") || a.equals("d"))
}
