How to compile and run

Compile and Run

• Open a terminal and move to the src directory inside the java folder that you extracted from java_chess.zip.
• Execute javac com/wizeline/chess/*.java to compile all files.
• To run the application use java com.wizeline.chess.Main (make sure that the com and images directories are at the same level).

Generate and run JAR

Another alternative to run the application is to generate a JAR file.

• Open a terminal and move to the src directory inside the java folder that you extracted from java_chess.zip.
• Execute javac com/wizeline/chess/*.java to compile all files. Then execute jar cfe Chess.jar com.wizeline.chess.Main com/wizeline/chess/*.class images
• Once the jar file is created you can execute it with: java -jar Chess.jar or by double click it in the finder/windows explorer.

How to add pieces to the board

As shown in the constructor of Window.java, the board class is initialized with a HashMap where the key is the position and the value the kind of piece (See Window.java for more information), the following is an example of random pieces being initialized:

board = new Board();
// Adding pieces to the board
board.pieces.put("a8", "bR");
board.pieces.put("b8", "bN");
board.pieces.put("c8", "bB");
board.pieces.put("d7", "bP");
board.pieces.put("e1", "wK");
frame.add(board, BorderLayout.CENTER);

How to handle the Input

In this example we handle input written in the following way e1e4, which will move the piece found at tile E1 to tile E4. To execute this example follow these steps:

• Edit file Window.java under the comment //TODO: Process input from text field by adding the following code:

String origin = input.substring(0,2);
String target = input.substring(2,4);
String piece = board.pieces.get(origin);
board.pieces.put(target, piece);
board.pieces.remove(origin);
outputLabel.setText("White Player's turn");
board.draw();

• Compile and run the application (Check the "How to compile and run" section)
• In the input field type the position of a piece and the target tile (Example: e1e4) . Press the Return/Enter key or click the Submit button.
