What if we wee painting all of the spaces in a checkerboard, and we were
¿Qué pasaría si estuviéramos pintando todos los espacios en un tablero de ajedrez y estuviéramos
painting them blue and red? When we're drawing this rectangle we need to figure
pintándolos de azul y rojo? Cuando estamos dibujando este rectángulo tenemos que determinar
out whether it's going to blue or red based on the number of its indexes. We
si va a ser de color azul o rojo en función del número de sus índices. Queremos
want to write a method that takes the row and the column of a space, and then
escribir un método que tome la fila y la columna del espacio y después
gives us a one. If the space should be red and a zero if the space should be
nos de un 1 si el espacio debe ser rojo y un 0 si el espacio debe ser
blue. The public interface of this method might look like this. So, we need
azul. La interfaz pública de este método podría tener este aspecto. Así que, necesitamos
some mathematical expression which takes a row and a column and gives back a
alguna expresión matemática que tome una fila y una columna y regrese un
one or a zero. If the row and the column are both even or both odd, you should
uno o un cero. Si tanto la fila y la columna son ambas par o impar, deberías
get back a zero. If the row is odd but the column is even, then you should get
regresar un cero. Si la fila es impar pero la columna es par, entonces debes regresar
back a one for red. And if the row is even but the column is odd, you should
un uno o rojo. Y si la fila es par pero la columna es impar, también
also give back a one. In the checkerboard project that we provided for you in
deberías regresar un uno. En el proyecto de tablero de ajedrez que te dimos en
blue jay, you'll want to implement checkerboard painter, and write a test
BlueJ, podrás implementar el CheckerBoardPainter y escribir un método
method in checkerboard painter tester. Try running the main method of painted
de prueba en el CheckerBoardPainterTester. Intenta ejecutar el método principal para
checkerboard. Once you've finished, if you need a hint, think about what
PaintACheckerBoard (DibujaUnTablero) una vez que termines. Si necesitas ayuda, piensa sobre qué
happens if you add an even number to an odd number. Do you get an even number
sucede si agregas un número par a un número impar. ¿Obtuviste un número par
or an odd number?
o un número impar?
