These methods are very efficient when messages are not logged. Log5j also provides methods such as debugf, errorf, fatalf, logf, and tracef, which allow dynamic formatting of logging methods. The varargs feature allows us to pass any number of arguments to any logging method. In terms of style, it is similar to the Log4j, but it uses the varargs feature of Java which Log4j doesn't use. This library is available in Java5 or higher versions. Log5j is one of the light-weighted and fast logging libraries in Java. We can convert the pre-existing unmodifiable objects into JSON or can form them and generate them from the JSON by using the Google-json library. It has extensive support of Java generics and provides custom representations for objects. It provides methods such as toJson() and fromJson() for converting objects into JSON and vice versa. We need to convert the Java object into JSON and other formats when developing mobile applications and writing and using Rest APIs in Java applications. Google-json is similar to Jackson, which is mainly used to convert Java Objects to JSON and vice versa.

In order to learn more about Maven, visit. Maven helps us to add a set of jar files in each project, create the right project structure and build and deploy the project. Maven is a repository that manages configurations, documentation, build configuration, and dependency by specifying them in the pom.xml file. By using Maven, we can build java web and desktop applications. It is a comprehensive tool that is based on the project object model. Just like Apache Commons, Maven is also provided by the Apache. The Java Jackson library provides data binding and annotations, which can convert POJO objects into data or generate POJO from data. class file into a JSON format or JSON string. The Jackson JSON library is a parser/generator library for transferring a. Jackson library is basically a suite of data processing libraries. Besides JSON, there are many more data formats such as CSV, XML, BSON, and Avro.

The JSON format is one of the formats which is mostly used in software development. In software development, we have to save, load, and transfer data into various formats. In Java, we need to work with data of different types of formats. The Apache Commons has the following features:

The Commons Dormant is basically a repository that contains the inactive components.

The Common Sandbox is basically a workspace to develop java components.

The Commons Proper contains reusable Java components.

It has three parts such as Commons Proper, Commons Sandbox, and Commons Dormant.

sound is another library that is used for media content.Īpache Commons is another library or can say it is an open-source project which focuses on all aspects of reusable Java components.

The java.awt is available in the older version of Java.

The swing and java.awt are two libraries used to create GUI(Graphical User Interface).

The net library is mostly used for developing network applications.

In order to work with networks, connections, and sockets, provides all the required classes for it.

The math library is one of the libraries used for mathematical calculation, such as the sum of BigInteger or BigDecimal.

By using it, we can get the advantage of intensive use of I/O operations.

The nio is another library that stands for non-blocking I/O and is an alternative to java.io library.

It allows developers to use files in their Java applications.

In order to work with pipes and to read data from files, we need the io library.

In order to use data structures and collections in Java, we need util class because it contains the definition of all data structures and collections.

The lang library provides everything to us for writing code in Java.

We cannot write any program in Java without String, Enum, Double, etc.

These libraries are called at run time by JVM(Java Virtual Machine). Java Standard Library is one of the most popular and used libraries, which contains a list of libraries to make work easier. Let's understand each of the libraries one by one: Java Standard Library

Some of the most useful and popular libraries are as follows: Java provides more than thousands of libraries except standard libraries. Java provides a rich set of libraries, and its standard Java library is a very powerful that contains libraries such as java.lang, java.util, and java.math, etc. Java is one of the most popular programming languages.
