This article is the third of the GC expert series. In the first understanding of Java garbage Collection, we learned several different GC algorithm processing processes, the way GC works, the difference between the new generation and the old age. So, you should have known about the 5 GC types in JDK 7, and the performance impact of each GC.The second monitoring of Java garbage collection describes how the J

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

The first part walks into Java one, into Java1. OverviewJava is widely used in embedded systems, mobile terminals, enterprise servers, mainframe and other occasions, to get rid of the constraints of the hardware platform, to achieve the "write once, run everywhere" ideal2.

1. Preface Java application is a very common problem, how to read the Jar/war package and the path of the configuration file, different people according to different practices summed up the different scenarios, but others application will be due to the environment and other differences to find a variety of problems, this article from the principle of interpretation of best practice. 2.

Java multi-thread programming practices-general Linux technology-Linux programming and kernel information. The following is a detailed description. Java 5 adds a new class library concurrency set Java. util. concurrent, which provides a wide range of API multi-threaded programming for concurrent programs, making

StringBuilder instead of string objects at the right time, single-threaded using StringBuilder, stringbuffer in multithreaded situations. Allocate StringBuffer, arrays, array,vector and other capacities in advanceFor objects that need to be allocated continuously, it is better to allocate the capacity ahead of time, generally the default initial capacity is relatively small, such as the capacity of StringBuffer is only 16, if the default capacity is easy to reallocate after the full capacity

Java multi-thread programming practices Multithreading in Java programs is much easier to use than C or C ++, because the Java programming language provides language-level support. This article uses simple programming examples to illustrate how intuitive multithreading is in Java
