In Java programs, what happens when an uncaught Runtime. Exception is thrown, but is not handled by your program In the simplest Java programs run from the console and executed in a single thread, the default behavior is to. There are two common kinds of programs where the above behavior is not in effect. Swing applications. Today I want to introduce the topic of Java multithreading to you. This is a bit of an advanced topic, so if you are not familiar with Java programming, I. In Swing applications, the default behavior still prints the stack trace to the console, but the Event Dispatch Thread the main Swing thread is not terminated. The Event Dispatch Thread always remains alive, in spite of any Runtime. Exceptions thrown by your program. However, simply printing a stack trace to the console in a Swing application is not very informative for the average user. Instead, you should likely override Javas default handling of uncaught exceptions. Frequently Asked Questions about the GNU Licenses.

A source file will normally have include directives at the top, followed by declarations, definitions, and namespaces containing declarations and definitions. After the preprocessor has finished processing a source file, the compilation unit will only contain declarations, definitions, and namespaces at the top level. The behavior is undefined.
