Launcher Startup Class This article is the source analysis part of the parent delegation mechanism, and the parent delegation model in the class loading mechanism is very important for the stable operation of the JVM. But the source is actually relatively simple, then briefly introduce let's start with the startup class. there is a Launcher class Sun.misc.Launcher; take a closer look at this short line of

Always look forward to having an online eclipse website that wants to see a jar package that does not need to download this jar package locally and import Eclipse to see the source code of this jar. One day colleagues introduced a website www.grepcode.com really feel good, not only can see the source code of this jar,

Part 1th Vector IntroductionVectors are vector queues, which are classes added by the JDK1.0 version. Inherits from Abstractlist, implements the list, randomaccess, cloneable these interfaces.Vector inherits the Abstractlist and realizes the list; therefore, it is a queue, supporting the relevant add, delete, modify, traverse and other functions.Vector implements the Randmoaccess interface, which provides a random access function.

I. Background to the issueOften encountered to synchronize data, and the system comes with the replication function can not achieve incremental synchronization, each time to do the full amount of replication, the abnormal situation can only start again, very troublesome, excellent it is the kind of large file processing, it is time-consuming.Two. Solution1. Calculate the source directory data fingerprint2. Calculating the target directory data fingerp

1, Project ResearchBecause you need to study the problem of uploading breakpoints. Looking for a long time finally found a better project.In the googlecode above, the code to get down Super inconvenient, or configure the hosts just good, put the code back to GitHub above.Https://github.com/freewebsys/java-large-file-uploader-demoEffect:Upload, show progress, time

handling of NULL, and this strange thing can only be compared by = =.In general, it is the traversal of the array, if a matching element is found, the Fastremove is successful, the deletion returns true, otherwise false.This quick delete is nothing to be curious about: Private void fastremove (int index) { Modcount++ ; int nummoved = size-index-1; if (nummoved > 0) System.arraycopy (elementdata, index+1, Elementdata, index, nummov

1. IntroductionList in the data structure is expressed as a linear table, its elements are stored in a linear manner, the collection allows to store duplicate objects, list interface main implementation classes have ArrayList and linkedlist. Java provides the implementation of these two structures, this article is to be familiar with the next ArrayList of the source cod
