classes belong to Rt.jar, which is consistent with the results.Extension class Loader:The extension class loader is used to load extension classes from the Jre/lib/ext directory. You can put your jar in this directory, so there is no path problem, but there is a problem to note: If you put your jar under the Jre/lib/ext, if your class calls the system

Reprint please the head source link and the tail two-dimensional code reproduced together, this article from: http://blog.csdn.net/hejjunlin/article/details/52420803In the previous chapter, the paper analyzes the process of MediaPlayer from creation to Setdatasource, and despite the code, but does not know the dependent call relationship between the various libraries from the MediaPlayer ecology, in this article will make a supplement to the overall understanding. Look at today's agenda:

Use Rational Rose Reverse Engineering (java) to generate class diagrams (tutorials and error solutions) and rational Reverse Engineering When the project framework project code is obtained but there is no uml diagram, it is not easy to see the call relationship function flow between methods. How to generate a class

, simply convert it to a positive value, and then take the remainder after dividing it by the size of the array. The following is a simple Java hash function that applies to any objectint hashvalue = Maths.abs (Key.hashcode ())% Table.length;(The% binary operator (called modulo) divides the value on the left by the value on the right and then returns the remainder as an integer.) ）In fact, before release 1.4, this is the hash function used by various

Usage and depth of ThreadLocal class in Java multi-thread programming, javathreadlocal usage ThreadLocal, literally translated as "Thread Local" or "local thread". If you really think so, it will be wrong! In fact, it is a container used to store local variables of the thread. I think it should be called ThreadLocalVariable (local variable of the thread). I really don't understand why Sun engineers named it

VA is a very simple and ingenious language, and the basics behind it are simple, with two points in general: 1. Memory management of the JVM, understanding this, the problem of the object can be solved. such as thread safety issues, memory leaks, and so on. 2.JVM class Loading system, understand this, about the jar package configuration problem, including various appserver configuration, the application of the issue can be solved. The memory manageme

. We can make the program more scalable ... This later will be Java polymorphic when I will say:2. To make the program more clear, when we use the abstract class, no matter what the subclass is, we can basically see the function of subclass by abstract class, for example, person is abstract class, then we can know that

Java Concurrency Programming: the use of the thread classIn the previous 2 articles, we talked about the origins of threads and processes, and how to create threads and processes in Java. Today we will learn about the thread class, before learning the thread class, first introduce the threading-related knowledge: Sever

parent node (the Translator notes: In addition to the root node) can represent hierarchical relationships or order relationships of data elements. Common scenarios are the hierarchy of employees in an organization, the hierarchical relationships of XML elements, and so on. If the tree has a maximum of two leaf nodes per child node, then this tree is called a binary tree. Binary tree is a very common tree structure, because of its structure makes the insertion and deletion of nodes are very effi

Then select Driver template,driver name (optional), Connection URL, database username, database login password, then click Test Driver (test whether the database is connected successfu

In the first section, we implemented 5 classes. In this section, we then show you how to use UML class diagrams to design the remaining classes. To reduce space, this section focuses on UML class diagrams and applications, the Java implementation code is no longer described in detail. Six, Cgpoint class The Cgpoint

Two keywords extends: Generally the inheritance class, which cannot be inherited multiple times in java. Implements: generally refers to the implementation interface. Because java does not support multiple inheritance, an interface is used to implement a function similar to multiple inheritance. Example: [java]

Understanding the JVM virtual Machine principle is a necessary step for every Java programmer to practice. But because there are a lot of things in the JVM virtual machine to tell the relatively broad, in the current exposure to the JVM virtual machine principle of the tutorial or blog, the vast majority of the text-based description, it is difficult to give people a visual perception, after reading the feeling is still confused. Feeling the above, I

Dynamically generating a class is very helpful for technologies such as AOP,O/R mapping. For Java, it's not a big problem, but for. NET, it's a bit of a hassle (the main problem is that the generation of code needs IL), so it's probably also the reason that Java went a bit further in AOP, O/R mapping. Trouble is trouble, it can't be, dynamic generation of a simp
