Exceptions that the user want to be invoked when a particular criteria is not satisfied by the user.Eg. If the programmer want the user to give username necessarily,Then he can make an exception that if a user didnt give username then this exception is invoked.For this,1st we have to make an exception class of our own which mst will extend Exception class.Then make use of it in try,catch & use throw for throwing it explicitly.

You can create your own exception by extending the java.io.Exception.
Throw the that exception using throw like this :
public void method() throws userDefinedException {
try {
}catch(exception e) {
throw new userDefunedExcpetion();
}
