java documentation: Referencias de objetos. Esto debería ayudarlo a comprender una "excepción de puntero nulo": uno de ellos obtiene uno porque una referencia de objeto es nula, pero el código del programa espera que el programa use algo en esa referencia de objeto. En Java, los argumentos son pasados por valor, la copia puede ser una referencia o una variable dependiendo del tipo original de la variable. Desde ahora, usted puede utilizar las siguientes recomendaciones a fin de entender como la modificación de argumentos dentro del método afectan a la variable original: If the json will only ever be parsed by your java code, then use the same parser to validate it.

Although the format strings are similar to C, some customizations have been made to accommodate the Java language and exploit some of its features. Also, Java formatting is more strict than C's; for example, if a conversion is incompatible with a flag, an exception will be thrown. In C inapplicable flags are silently ignored.

Si te das cuenta, pudimos cambiar el nombre desde otra función. Por lo tanto, los objetos sí se pueden modificar desde otra función y concluimos en que los objetos se pasan por referencia. Objetos no pueden ser cambiados si se crea una nueva instancia. Las referencias en Java no son punteros ni referencias como en C++. Este hecho crea un poco de confusión entre los programadores que llegan por primera vez a Java.

Una referencia en cualquier lenguaje de programación hace alución a la posición en memoria RAM que tiene dicha variable u objeto, al contrario de C++ en Java no nos tenemos que preocupar por manejar a mano los punteros hacia esas posiciones, ya que se encarga de manejarlas el mismo.
