en este post<\/a>, todo en Java son clases y objetos, as\u00ed que s\u00ed, las variables son clases y contienen objetos.<\/p>\nY para tener un primer vistazo volvemos a nuestro famoso ejemplo del hola mundo:<\/p>\n
class HolaMundo {\r\n public static void main (String args[]) {\r\n String hola = \"\u00a1Hola Mundo!\";\r\n System.out.println (hola);\r\n }\r\n}<\/pre>\nAqu\u00ed vemos como una caja de tipo String con el nombre de hola y, dentro de esa caja, vemos un mensaje de “\u00a1Hola Mundo!”. \u00a1Aqu\u00ed tienes tu primera variable!<\/p>\n
Ahora que ya la tenemos, \u00bfc\u00f3mo podemos usarla? Justamente en la siguiente l\u00ednea vemos que usamos la variable “hola” directamente para imprimirla. En este caso el comando de System.out.println espera recibir una caja de tipo String y obtendr\u00e1 su valor para generar el mensaje y lo imprimir\u00e1.<\/p>\n
Ok, here we use a box of type String which the name of hello and, inside that box, we have a message of “Hello World!”. Yes, that is your first variable.<\/p>\n
En futuras entradas veremos que tipos de variables hay en Java.<\/p>\n","protected":false},"excerpt":{"rendered":"
