Exceptions and errors:Exception:In Java, program errors are mainly syntax errors and semantic errors. Errors that occur during compilation and runtime of a program are collectively referred to as exceptions. They are VM (Virtual Machine) errors) one way to notify you, through which VM lets you know that you (developers) have made an error and now have a chance to

ClassCastException errors are often encountered in Java programming , and the classcastexception is a runtime exception that is thrown when the JVM detects a conversion incompatibility between two types. This type of error usually terminates the user request. This model attempts to provide you with some basic elements to understand and exclude the most common causes of classcastexception errors.Why does thi

difference between the exception and the error is that the exception can be handled by the developer and error when the system was originally brought, generally unable to deal with and do not need our programmers to deal with. 1. An exception is an event that occurs during the execution of a program that interrupts the operation of normal instructions. 2. Error,
