The recent use of Eclipse to launch Tomcat eofexception abnormal, although not affect the use, but always feel uncomfortable, to find a way to solve a bit. After analysis, the original is Tomcat did not shut down, I basically every time through the task Manager to kill the thread, mainly in the project some resources are not released, under normal circumstances Tomcat will not shut down, so only kill the process. Because Tomcat does not shut down prop

unchecked exceptions (unchecked exception). Another class of exceptions in the Java language is check exceptions (checked exception). Checking for exceptions is those that should be handled in the program, and not checking for exceptions are those that cannot be interfered with (such as an error class exception) or exceptions that can be avoided entirely under control, such as an array out of bounds error. The declaration of a method must indicate al

The exception that is derived from the runtimeexception exception, which is caused by a program error. Other exceptions are not program-induced. Several cases that derive from the RuntimeException exception: Wrong type conversions Array access out of bound

1. What about the dynamic loading mechanism ??Learning Java is easier to understand the idea of OOP than C ++. After all, C ++ has a lot of process-oriented components. Many people can back up the features of the Java language, the so-called dynamic loading mechanism, and so on. Of course, the concept is often first remembered and then digested. How many people have actually realized the dynamic loading mec

Java. io provides a comprehensive IO Interface, including file read/write and standard device output. In Java, IO is input and output based on a stream. All data is serialized into the output stream or read from the input stream. In specific use, many beginners are very vague about the use of Java. io packages. This article will detail the use of
