I have my Java program and I get a NullPointerException and I have seen other questions but they are from people with other programs and it does not work for my program and I want to leave you here the 2,000 lines of my program so that you can solve the problem for me but people do not let.
Look, my program is like this
Object a = null;
// 500 líneas de código
// Dentro de un bucle, dentro de un if, dentro de un for...
a = algunaFuncionDeMilLineasQueNoTeVoyAMostrar(
parámetrosDeLosQueNoTeDiréElValor)
// Cerrando for, cerrando if, cerrando bucle.
// Otras 500 líneas de código
// Una de estas líneas lanza el NPE, pero no te diré cuál.
a.toString();
z.hazAlgunaCosa();
x.haxY().hazM().cuantoFaltaParaLasVacaciones().andaMiraUnPatoQuePasaPorAhi();
It's wrong? Why isn't there a one-size-fits-all solution for NullPointerExceptions (NPEs) if they happen so often?
