It has been rightly said that you can’t do the job right without the right set of tools. And if you are a Java developer then you must be knowing how important the tools and libraries could be. Fortunately, there are plenty of Java libraries available that make it simpler for you to write Java code- and help you make your Java based projects efficient and successful.
In this post, we are going to reveal a list of some of the most popular Java libraries for a variety of applications. All of them offer vast amounts of functionality, and come bundled with superb design and coding tools.
So, without much ado, let’s have a look at each of them:
Internal Libraries
1. Java.lang
The java.lang is an highly efficient JavaScript library which features a set of specific classes and interfaces that are crucial for getting the grasp of the core Java language. One of the most highlighted classes of this package are Object, which is the main source of class hierarchy, and Class, which represent classes during run time.
2. Java.util
It’s a useful library with several generic java utilities including collections framework, formatted printing, scanning, event model, and more.
3. Java.io
Java.io comes complete with various classes that handle and manage crucial input and output operations in Java. The classes are divided into multiple categories and are specifically designed to perform the functions related to that category.
4. Java.net
Java.net library is a rich source of multiple classes and interfaces that provide you a solid framework for working with Java networks. The Java.net package can be split into two sections: a low level API and a high level API. Low level is dedicated for the classes such as InetAddress whereas high is developed for working with URL, URI URL connection, and HTTPUrlConnection.
5. Java.security
Java.security library comes packed with multiple classes that provide users with a better facility to encrypt a file with the help of a provided key. The library is compatible for cryptograph and digital signature.
6. Java.sql
Jav.sql is a library which features all the SQL related classes and interfaces. The library is also great in providing the API for accessing and processing data saved in the data source.
Utility Libraries
7. Apache Common Collections
The Apache Common Collections comes complete with many powerful data structures that help you speed up the process of developing competitive Java applications. It also provides a handy collection of various tools and utility methods that help you enhance development related objects effectively and efficiently.
