installation package creation tool, and finally press the entire program from 40 m to 8 M. Let's take a look at the entire operation process, and we will not write any tedious information about JRE slimming, sun's JRE slimming program is also underway. I believe that there will soon be a smaller slim version of JRE, and there is no need to bother myself.The following is a complete Java program named myload

the object is invoked. The Clinit method is a class constructor method that is not called until the initialization phase of the JVM is loaded.Execution purposes are different: init is the initialization of non-static variable parsing, while Clinit is initializing static variables and static blocks of code.Third, class loaderThe virtual machine takes the "fully qualified name of a class to obtain a binary byte stream that describes this class" in the class load phase, which is implemented outsid

Lambda Expressions Explanation of Java 8Java 8 Adds the purpose of Lambda Expressions: to make the code simple and easy to read and eliminate excessive redundant code (as much as possible to make the compiler do code conversion work, it can also be considered as the role of syntactic sugar). people who have used the C and C + + languages remember that their function arguments can be function pointers as cod

Click to enter _ more _java thousand ask1. What are the 8 basic data types of Java?Understanding data Types Look here: What is the Java type of dataThe basic data types include 4 categories, each of which corresponds to a wrapper for a class type (wrapper Class), as follows:Learn about the basic type wrapper look here: [What is the basic type wrapper][3][3]:

There are eight basic types of Java, the basic types can be divided into three categories, character type char, Boolean and numeric type Byte, short, int, long, float, double. Numeric types can also be divided into integer type Byte, short, int, long, and floating-point type float, double. Numeric types in Java do not have unsigned, and their range of values is fixed and will not change as the machine hardw

Time Stamp Lock Multithreaded code has long been a poison for server developers (ask Oracle's Java language architect and parallel development guru Brian Goetz). Java's core libraries continue to incorporate complex usage to reduce the thread latency when accessing shared resources. One of these is the classic read-write lock (Readwritelock), which allows you to divide the code into two parts: a write that requires mutual exclusion and a read that do

Why?Why do we need lambda expressionsThere are three main reasons:> more Compact CodeFor example, the existing anonymous inner classes in Java, as well as listeners (listeners) and event handlers (handlers), are very lengthy> Ability to modify methods (I personally understand code injection, or a bit like JavaScript that passes a callback function to another function)For example, the contains method of the collection interface returns True if and only

This article does not introduce Lambda's past life, this is only a detailed understanding of the application of lambda expression. And the difference point with the inner class.Lambda expressionLambda expressions are new syntactic sugars introduced in the Java SE 8 release. Consider a function as a method parameter and code as data.Lambda expression Syntax: Lambdaparameters-Lambdabody The lamb

There has been much discussion about "Java 8 brings functional programming to Java", but what is the true meaning of this statement? This article discusses the function, what it means to a language or a programming approach. Before replying to "How is Java 8 Functional prog

Java 8 Stream API details one, Stream API introductionJava 8 introduces a new stream API, which is completely different from the InputStream and outputstream in Java I/O packages, unlike the Stax stream for XML parsing, and unlike Amazon Kinesis stream for real-time processing of big data. The Stream API is more like a
