worth mentioning that the basic method of all parts of this class is thread-safe. This method is also referenced in a class of swing. ObjectInputStream, this class can be said to be more Implements two interfaces, Objectinut: Defines the types that can be read, Objectstreamconstants: Defines constants for reading file types, uses ReadObject to distinguish what type of object is read, and reads from serialized objects , it is necessary to judge what object is read by the f

Guava Chinese is pomegranate meaning, the project is a Google Open source project, contains a lot of Google Core Java Common library. 1. Fundamental tools [Basic utilities] Make it more comfortable to use the Java language 1.1 Using and avoiding null:null is ambiguous and can cause confusing mistakes, sometimes it makes people uncomfortable. Many guava tool clas

The method for loading a library in Java is related to its classloader. Different JVMs have different classloader. This section describes the loading sequence of the built-in JVM of j2sdk. First, Java loads the jar (ZIP, directory) contained in the parameter according to the system parameter classpath. As long as you use this JVM, you do not need to set classpath

If the jar package Library has the same package path and the same class name when running JAVA, will the JVM report an error? Of course not! JVM only loads the earliest CLASS First, the JVM will load its own default package, and then load all the JAR files under the EXT directory to the classpath. Now there are two JAR packages, kj0213w.jar summer. jar, which both have the package path cn. isto. If there is

The Objectmapper class is the main class of the Jackson Library. It provides functionality to convert Java objects to match the JSON structure, and vice versa. It uses Jsonparser and Jsongenerator instances to implement JSON's actual read/write. class declarationthe following is a declaration of the Org.codehaus.jackson.map.ObjectMapper class: public class Objectmapper extends Objectcodec impl

Jackson is a set of data processing library tools for the Java platform, and Jackson's main function is to provide JSON parsing and generation, and Jackson also provides additional class libraries to support the processing of Avro, CBOR, CSV, Smile, XML, and YAML, It's very powerful and it's great to work with JSON data in Java.The relevant sample code:{ "name" :{"First": "Joe", "Last": "Sixpack" } , "Ge

The Apache Crunch (incubator project) is a Java library based on Google's Flumejava library, which is used to create MapReduce pipelining. Similar to other high-level tools used to create mapreduce jobs, such as Apache Hive, Apache Pig, and cascading, Crunch provides a pattern library for common tasks such as connectin
