You can declare multiple exception thrown by method in
throws keyword by separating them in common
e.g. throws IOException, ArrayIndexBoundException etc,
while you can only throw one instance of exception using
throw keyword e.g. throw new IOException("not able to open
connection").

Answer / aravinda reddy
Whenever we want to force an exception then we use throw
keyword,throw keyword can also be used to pass a custom
message to the exception handling module i.e. the message
which we want to be printed. throw we will use at statement
level.
Whereas when we know that a particular exception may be
thrown or to pass a possible exception then we use throws
keyword. Point to note here is that the Java compiler very
well knows about the exceptions thrown by some methods so
it insists us to handle them. Method Level
