Atunci cand programul creeaza prea multe obiecte, fara a fi dereferentiate la un moment dat pentru a fi eligibile pentru garbage collection, este posibil sa ajungem in situatia in care se arunca:
VirtualMachineError
OutOfSpaceError
StackOverflowError
ThreadDeath
IOError
OutOfMemoryError
La compilare:
Se verifica toate exceptiile
Se verifica exceptiile checked
Suntem obligati sa tratam exceptiile checked ce ar putea fi aruncate de o metoda
Se verifica toate exceptiile ce extind Throwable
Se verifica toate exceptiile ce extind Exception, dar nu fac parte din ierarhia lui RuntimeException

Este o clasa ce implementeaza RuntimeException
Este o clasa ce extinde RuntimeException

Poate fi anuntata in semnatura unei metode prin intermediul clauzei "throws"
Nu poate fi prinsa cu clauza "catch"

Atunci cand aruncam o exceptie dintr-o metoda, facem lucrul acesta instantiind exceptia cu new NumeExceptie()
