Deep understanding of Java Virtual Machine: JVM advanced features and best practices (in-depth analysis of JVM Based on issues such as memory management and high concurrency) Provides a comprehensive and in-depth analysis of JVM based on core content such as memory management, execution subsystem, programming compilation and optimization, and efficient concurrency. This deeply reveals the working principle

This article Importnew-dug pit master Zhang without permission, prohibit reprint!Exception handling plays a very important role in writing robust Java applications. Exception handling is not a functional requirement, it requires graceful handling of any error conditions, such as resource availability, illegal input, null input, and so on. Java provides a number of exception handling features, implemented th

Java concurrent programming Summary 5 -- ThreadPoolExecutor, java concurrent programming practices I. Introduction to ThreadPoolExecutor In jdk1.8, there are four constructors. To ThreadPoolExecutor (int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue 1,CorePoolSize: Core thread pool size 2,MaximumPoolSize: Maximum thread pool

In practice, exception handling is not just as simple as knowing the syntax. Writing robust code is more like an art. In this article, we will discuss Java Exception Handling best practices. These Java best practices follow the standard JDK library and several open-source code for handling errors and exceptions. This i

Java provides a set of APIs to support the interaction between threads. A set of APIs waiting to be notified in the object classWait ()Notify ()Notifyall ()It is important to note that you must never call the Wait () method outside of the loop. (Open a separate article to discuss) The following uses consumer and producer issues to demonstrate the use of the above API:Packagexiancheng;publicclasspc{publicstaticvoidmain (String[] args) {shareds=newshare

;=) throw new Maximumcountreachedexception ();}Useexceptionsforflowcontrol () uses an infinite loop to increment the counter until the exception is thrown. This writing not only reduces the readability of the code, it also makes the code slow. Remember that exceptions are only used in cases where an exception occurs.3. Do not ignore exceptionsWhen an API method throws checked exception, it is trying to tell you that you need to take certain actions to deal with it. If it doesn't mean anyt

--Leverage advanced Java best practices to improve the architecture and design of existing and future Java EE applications Author: Tarak Modi Although many articles have discussed the best practice of Java EE. So, why do I have to write another article. What is the difference between this article and the previous ar

executed across different JVM implementations or versions. With JNI, the local code can interact with Java objects at will, obtain and design field values, and call methods, without being as limited as the same functions in Java code. This freedom is a double-edged sword: It sacrifices the security of Java code, in exchange for the ability to complete the tasks

Research on JAVA reverse TCP practices in Metasploit When studying the JAVA deserialization vulnerability of CVE-2015-7450, there is a problem: in WebSphere, this vulnerability can only execute commands, but not echo the execution results. In this case, the common practice is to use commands such as wget or curl to execute an http request and send the required

Introduction Over the last decade or so, people have written a lot about Java™platform, Enterprise Edition (Java EE) best practices. There are now more than 10 books and hundreds (perhaps more) of articles that provide insights into how Java EE applications should be written. In fact, there are so many references in t

Lambda best practices in Java 8 (1) Java 8 has been launched for some time. More and more developers choose to upgrade JDK. The hot news shows that JDK 7 is the most popular, followed by JDK 6 and 8. This is a good thing! In 8, Lambda is the most popular topic, not only because of changes in syntax, but more importantly, it brings the idea of functional programm

recycled by GC because they are circular references to each other.2. Root Search algorithmA series of objects named "GC Roots" are used as starting points from which to search down, and when you reach objects that are not on the GC Roots reference chain, even if they are related to each other, they are still considered recyclable objects.Using the theory of graph theory, can be expressed as GC roots to the object unreachable .3. Better understanding of "references"In
