How do I transform this code into something simpler that I am more familiar with? [closed]

问题

I am currently in my first year of Java and have stumbled upon this code on the internet about a battleship game. What I would like to do is understand this code in more simple code. The part that confuses me is the first line: "computerGameBoard = new GameBoard(true, event ->". I am familiar with buttons and how they have action events, but how does this code compare to that and is it possible to turn this into a similar action event to a button? Could I split it into another method? Thanks in advance. Also note that the line of code below should be attached to the code segment, but its not.

    computerGameBoard = new GameBoard(true, event ->
    {
        if (!playing)
            return;

        BoardSquare boardsquare = (BoardSquare) event.getSource();
        if (boardsquare.wasHit)
            return;

        AIMove = !boardsquare.fire();
         System.out.println("enemyBoard shipcount:"+computerGameBoard.shipcount);
        if (computerGameBoard.shipcount == 0) {
            System.out.println("Winner!");

        }

        if (AIMove)
            AI1();
    });

回答1:

An example of onClickListener() without lambda:

mButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // do something here
    }
});

can be rewritten with lambda:

mButton.setOnClickListener((View v) -> {
    // do something here
});

So your code is using Lambda expression (Java 8 feature)
