Venga, pues estábamos aquí. 00:00:00
Bueno, pues ¿cuál va a ser el efecto de este método? 00:00:03
Sumar esta cantidad a lo que ya tenga la cuenta. 00:00:06
Luego, ¿tiene que devolver algo como valor de retorno? 00:00:10
No tiene que devolver nada. 00:00:13
El objeto que llame al método ya verá reflejada su acción 00:00:15
en que su propiedad cuenta quedará modificada. 00:00:20
Entonces, este método es simplemente esto. 00:00:23
Hasta luego. 00:00:28
Ya está y este método ha terminado. 00:00:31
Esta es la propiedad del objeto que llame al método 00:00:34
y cantidad es el parámetro. 00:00:37
¿Que queremos poner esto? 00:00:40
Bueno, ponemos eso. No sobra. 00:00:43
Pero en este caso no hace falta 00:00:46
porque el identificador cuenta no tiene ninguna ambigüedad. 00:00:49
No tiene ninguna ambigüedad. 00:00:52
Solo hay uno que se llame cuenta aquí. 00:00:54
Solo hay uno que se llame cuenta, que es este. 00:00:57
Entonces, no hace falta poner el div. 00:00:59
Te lo ponemos, no pasa nada. 00:01:01
No es necesario. 00:01:03
Ah, espérate, perdón. 00:01:06
Sí, sí, sí. 00:01:09
Si la cantidad es negativa, entonces no la ingresa. 00:01:11
Entonces, hombre, habrá que meterlo en un if, efectivamente. 00:01:14
Vale. 00:01:28
Ahora sí. 00:01:31
Pues este método ya está. 00:01:34
A ver. 00:01:37
Más métodos que pueden hacer los objetos cuenta. 00:01:40
Pues el otro, retirar y ya está. 00:01:44
... 00:01:58
A ver, retirar. 00:02:06
Se quita la cantidad. 00:02:08
Pero si, como resultado de hacer la resta, 00:02:10
se queda en negativo, se le pone a cero. 00:02:13
Vale, pues entonces aquí... 00:02:16
... 00:02:20
...pues esto mismo se podría hacer. 00:02:24
