ASIGNATURA: PROGRAMACIÓN ORIENTADA A OBJETOS. TEMA 5: 5: “EXCEPCIONES “EXCEPCIONES”” TITULO DEL ENSAYO: REPORTE DEL EJERCICIO 8. PRESENTA: MORALES SOLÍS BRANDON OMAR. NO. CONTROL: 20510397. 20510397. SEMESTRE: 2. GRUPO: B. CATEDRÁTICO: LIC. GUSTAVO REYES HERNANDEZ. FECHA: 29/06/2021.
Objetivo.
Reutilizar una aplicación vieja que en este caso será el ejercicio 2 y con base a lo ya realizado darle un tratamiento con ayuda de un manejador de excepciones para así lograr que el programa no se cierre de una manera inesperada o imprima en la terminal mensajes de error.
Desarrollo. Como se mencionó anteriormente se reutilizará la información del ejerció 2.

Resultados sin manejador de excepciones.
Excepción generada porque el usuario digita otro formato de número. Debido a que este programa está diseñando para que el usuario digite tipos de datos da tos float. Está excepción recibe el nombre de RuntimeException(excepciones no comprobadas) en palabras sencillas son errores cometidas por el programador.
Por lo que se prosigue a solucionarlo con un manejador de excepciones e xcepciones es decir se agregara el siguiente fragmento de código: try{ //Atrapa el error. } catch () { //Instrucciones a realizar para tratar el error. } En la parte del código de la interfaz que lo requiera.

Resultados con manejador de excepciones.
Como podemos ver ya no se generan errores. Se soluciona el error generando un mensaje en una ventana emergente.
Conclusión. Al haber hecho esta práctica de programación puedo decir que las excepciones son casos de error que pueden suceder en un programa provocando que lance mensajes de error en la terminal o se termine cerrando de una manera muy brusca. Por lo que la forma más fácil de resolver este problema que se enfrenta cualquier programador es con tratamiento de yexcepciones que solución. consiste en un fragmento de código que ayuda permiteuncapturar el error dar una posible Otra cosa muy importante que aprendí es que existen dos tipos de excepciones las cuales son: IOException (excepciones comprobadas). En palabras sencillas son errores que no son culpa del desarrollador de Java. RuntimeException (exc (excepciones epciones no compr comprobadas). obadas). En palabras sencillas son errores que son culpa del desarrollador de Java.

En está practica que realice puedo decir que la excepción cometida es un RuntimeException porque es culpa mía debido a que no programe para el caso en el que el usuario se le ocurriera digitar un tipo de dato que no sea float. Por lo que lo soluciones dándole un tratamiento de excepciones, pero soy consiente que esa no es la mejor manera de solucionarlo debido a que es un error mío por lo que mi obligación es resolver el error sin ayuda del manejo de excepciones debido a que eso no se considera una buena práctica de programación.
