In this article, I remember when I was in the company internship, the first formal, really meaningful task-the company will release the APK for code confusion.What is code obfuscationConfusion is the re-organization and processing of the published

PrefaceJdk,java Development Kit.We must first realize that the JDK is just a Java base Class library, which is the base class library developed by Sun, and that's it, the JDK itself and the class library we write ourselves to summarize, technically,

1, an object from which a sequence of bytes can be read into an input stream, an object to which a sequence of bytes can be written to do the output stream. The source of these byte sequences can be a file or a network connection or a block of

Introduction to Annotations (Annotation)Annotation (annotations) is a feature introduced in JDK5.0 and later versions. Annotations are a new type of Java (similar to interfaces), and are at the same level as classes, interfaces, enumerations, which

First, prefaceWhen coding, we always find a warning that the following variables are not being used:The code above is compiled and can be run, but the exclamation point in front of each line seriously hinders the breakpoint we have to determine if

I. The concept of serialization and deserialization　　The process of converting an object to a sequence of bytes is called serialization of an object .　　The process of reverting a sequence of bytes to an object is called deserialization of the object

What is an annotation (Annotation):　　Annotation (note) Is that Java provides a way and a way for an element in a meta-program to correlate any information with any metadata (metadata). annotion (annotation) is an interface that a program can use to

A lot of times we copy an object instance A to instance B, and when we do something with instance B, we modify instance B to make sure that the modification to B does not affect the normal use of a, you need to use a deep copy. I found some deep

First, the concept of serialization and deserialization The process of converting an object to a sequence of bytes is called serialization of objects.The process of restoring a byte sequence to an object is called deserialization of an object.There

1, StringBuffer The Append method has the errorCause analysis: Is the default JRE system library for project and the configured JRE mismatch.Workaround: Project Properties->add libray->jre System library->alternate JRE (select Sun JDK 1.6.0_13)2,

Original address: http://developer.51cto.com/art/201202/317181.htm1. What is the serialization of Java objectsThe Java platform allows us to create reusable Java objects in memory, but in general, these objects can exist only when the JVM is running,

The problem of deep copy and shallow copy is always encountered, here are some tests, the code is as follows:/* To change this template, choose Tools | Templates * and open the template in the editor. */import Java.io.bytearrayinputstream;import

There are a lot of warnings during the Java compilation process, many of which are secure, but there are a lot of warnings for each compilation that affect our filtering and modification of error, and we can add@SuppressWarnings ("XXXX") to

What is an annotation (Annotation):　　Annotation (note) Is that Java provides a way and a way for an element in a meta-program to correlate any information with any metadata (metadata). annotion (annotation) is an interface that a program can use to

The "object serialization" of Java allows you to convert an object that implements the serializable interface into a set of byte, so that you can restore the byte data and reconstruct that object accordingly. This is true even in cross-network

Last weekend, the basics of Java have done a collation, where the Java serialization and deserialization of the data in detail, here to make a note, I hope to also help to read this article friends. First, the concept of serialization and
