Exceptions include compile exceptions and run-time exceptions, while compile-time exceptions are mainly our syntax exceptions, and run-time exceptions are primarily exceptions that occur during code runtime.Exceptions are handled as objects in Java, the root class is the Java.lang.Throwable class, and many exception cl

Exception classification in Java, Java Classification The following describes several common exception types to help you identify program errors when an error occurs: (1) Exception root classes of various exceptions If you do not know where the

Java's exception handling mechanism can make the program have excellent fault tolerance and make the program more robust. The so-called exception is the problem that prevents the current method or scope from continuing to execute, and when the program runs with an exception, The system automatically generates a exception
