The figure above shows a call stack. Explain how a call stack works.
What will be an ideal response?
When a method throws an exception and the method does not catch it, the exception is thrown to the next method up the call stack, or, in other words, to the method that called the offending method. If methodA() calls methodB(), and methodB() calls methodC(), and methodC() throws an exception, Java first looks for a catch block in methodC(). If none exists, Java looks for the same thing in methodB(). If methodB() does not have a catch block, Java looks to methodA(). If methodA() cannot catch the exception, it is thrown to the Java Virtual Machine, which displays a message at the command prompt.
