inherently not equivalent, simply because the GC generational collection extends to the method area, but the fact that the method area is implemented in a permanent generation is not very good, Because this is more easily out of memory overflow, after all, the method area is also a size limit, can be set through (-xx:maxpermsize=128m)
Java virtual machines have a loose limit on the method area, can also be discontinuous memory, and can choose dynamic expansion, and the method area of garbage co

Java provides two types of exception classes, error and exception, which have a common parent class-throwable.
Error indicates that the program has made a very serious error during the run and that the error is not recoverable, such as OutOfMemoryError, Threaddeath, etc.

Microsoft uses UDDI at run time

Summary:This article outlines the use of UDDI at run time, discussing the infrastructure of UDDI (provided by the public Registry and UDDI Services in Microsoft Windows. NET Server) as a WEB service to support client applications.

The program timing function is not very useful, but when writing the sorting algorithm with the program timing function can be very intuitive to feel the time of the different sorting algorithm. (assuming, of course, that the amount of data involved is large enough)There are two ways to get time in Java:1. Use the Calendar class (package as Java.util.Calendar) to get the current

In earlier versions of Apache, the application itself must be able to handle the details of a variety of specific operating system platforms and invoke different processing functions for different platforms. With the further development of Apache, the Apache organization decided to separate and develop these universal functions into a new project. In this way, the deve

This feature consists of a syntax that defines the annotation type and a syntax for describing an annotation declaration, an API for reading annotations, a class file with annotation modifications, and a annotation processing tool.
