How do you repair an unhandled exception?
You can stop an unhandled exception by handling it. When your program crashes it will tell you exactly where it crashed and what exception it ran into. Dealing with the exception is the hard part. Generally, you want to take one of two approaches. The first is to make sure that the exception cannot happen. You may, for example, have to validate data to make sure that your users aren't allowed to give input which would result in a division-by-zero exception. The second is to allow the exception to be thrown, but use a try-catch block to catch it and print out a useful message instead of crashing. The method you choose will depend on what your program is supposed to do, who is using it, what exceptions are being thrown, where they're being thrown, etc. There's no silver bullet solution for handling an exception.

ClassCastException - Thrown when attempting to cast a reference variable to a type that fails the IS-A test. 3. IllegalArgumentException - Thrown when a method receives an argument formatted differently than the method expects. 4. IllegalStateException - Thrown when the state of the environment doesn't match the operation being attempted, e.g., using a Scanner that's been closed. 5. NullPointerException - Thrown when attempting to access an object with a reference variable whose current value is null. 6. NumberFormatException - Thrown when a method that converts a String to a number receives a String that it cannot convert. 7. AssertionError - Thrown when a statement's boolean test returns false. 8. ExceptionInInitializerError - Thrown when attempting to initialize a static variable or an initialization block. 9. StackOverflowError - Typically thrown when a method recurses too deeply. (Each invocation is added to the stack.) 10. NoClassDefFoundError - Thrown when the JVM can't find a class it needs, because of a command-line error, a classpath issue, or a missing .class file.
What is throw keyword in java?
The throw keyword is used from within a method to "throw" an exception to the calling method. In order to throw an exception, the method signature must indicate that it will throw an exception. For example: public void foo() throws Exception { } When you want to actually throw the exception, you can do it a few different ways: throw new Exception("Exception message"); or from within a catch block ( catch(Exception ex) ): throw ex;
