See there are two types of exceptions...

1.Checked Exceptions-Some methods throw exceptions in their definition,so compiler checks it at compile time.Such as ClassNotFoundException,NOSuchMethodException.

2.UncheckedException-Compiler does not check for these exception and it is the job of run time environment to find the exception and create an object and throw it i.e. it is handled by default handler.

There are two types of exceptions checked and unchecked expections:

1.Checked exceptions are exceptions which are expected and thrown and handled in a well written program.For example if you are reading from a file,it may be anticipated that the file does not exist.Hence you write code to handle it.
Handling exception includes usage of try ,catch,finally block.You can alternatively throw and exception to handle it higher in method call stack.

A programmer is forced to handle checked exceptions else there is a compiler error

2.Unchecked exceptions need not be handled.A program is expected to never recover from this exceptions.For example NullPointerException.

A programmer has a option of handling unchecked exceptions or he may choose to ignore them.
