Anyone who wants to learn Java should start by finding a tutorial that fits their learning style. Whether you prefer hands-on learning or more theory-based learning, there’s a Java tutorial out there for you.
You should also make sure that the tutorial you choose covers all the basics of the language and provides plenty of exercises so you can practice what you’ve learned. Here is our team suggests the 5 best way to learn Java.
What is Java?
Java is a programming language that has been designed to be general-purpose and class-based. It’s an object-oriented system with lower implementation dependencies, meaning it can run faster than other languages on less powerful hardware without compromising security or reliability. This makes Java ideal for developing apps across many platforms such as laptops/desktops (PCs), data centers, or game consoles among others!
Components Of Java Programming Language
There are a number of components that make up the Java programming language. These include:
The Java Virtual Machine (JVM)
This is the component that runs Java code. It’s responsible for translating bytecode into machine code that can be run on different platforms.
Java Runtime Environment (JRE)
The Java Runtime Environment (JRE) is a software package that contains everything you need to run Java applications. It includes the Java virtual machine, the Java class libraries, and other supporting files.
The JRE is required for running Java programs, and it can be installed on Windows, Mac OS X, and Linux. It’s also included in the JDK (Java Development Kit), which is a more comprehensive software package that includes tools for developing Java programs.
Classes and Objects
In Java, everything is a class, including the core classes that are provided by the language itself. Classes are composed of properties and methods, and objects are instances of classes.
Data Types
Java has a number of data types that you can use in your code, including boolean, byte, char, short, int, long, float, and double.
Operators
Java has a range of operators that you can use to manipulate data types.
Control Flow
There are a number of statements that you can use to control the flow of your code, allowing for conditional execution or loops that can iterate over a section of code multiple times.
Packages and Import Declarations
Java treats all features as packages, allowing you to group similar items together, and import declarations allow you to access packages that might not be part of the default Java installation.
Types of Java Platforms
There are a number of different Java platforms that you can use to develop applications. The most common is the Java Standard Edition (Java SE), which is the platform that most Java developers use. It includes a number of libraries and tools for developing desktop and server applications.
Another popular Java platform is JavaFX, which is a graphical user interface (GUI) library used for creating rich internet applications. JavaFX is included in the JDK, so you don’t need to install it separately.
There are also a number of mobile Java platforms, including Java ME and Java SE Embedded. Java ME is used for developing mobile applications, while Java SE Embedded is used for developing devices such as routers, printers, and automotive systems.
There are also Java platforms for developing enterprise applications, including Java EE and Java SE. Java EE is the platform used for large-scale mission-critical applications that need high availability, while Java SE Embedded is best suited for embedded development on small devices with limited resources.
Java Open-Sources Libraries
One of the best things about Java is the large number of open-source libraries that are available. These libraries allow you to add features to your applications without having to write the code yourself.
Some of the most popular Java open-source libraries include:
Apache Commons
This library contains a collection of utilities and components for Java developers. It includes classes for file handling, I/O, math, string manipulation, and more.
Google Guava
This is a library that contains a number of utility classes for Java developers. It includes classes for collections, caching, IO, math, and more. Guava is popular because it’s easy to use and provides a lot of functionality.
JHipster
This library is a Yeoman generator for creating Java-based web applications. It’s a popular choice among Java developers because it provides a lot of features and options, and it’s easy to use.
Maven
Maven is a build management tool used for Java development. It’s open-source and free to use, and it allows you to easily manage the build process for your applications. Maven can be used to compile Java code, create JAR files, and more. One of the best things about Maven is that it’s extensible. This means that you can add plugins to extend its functionality.
There are a number of plugins available, including plugins for compiling Java code, creating Javadoc documentation, and more. Maven is also popular because it’s reliable and easy to use. It has a simple XML-based configuration file, and it can be run from the command line or from within an IDE.
JUnit
This library is used for unit testing Java applications. It allows you to test individual classes or groups of classes in isolation.
Log4j
This library is used for logging Java applications. It allows you to track the progress of your application and log errors and warnings.
