Java is a popular programming language and software platform
Java is used to develop various types of applications, such as web applications, mobile applications, desktop applications, games, embedded systems, and more. Some of the most popular websites and applications that use Java are Google, Amazon, Facebook, Twitter, Netflix, Minecraft, Spotify, eBay, and many others. According to Oracle, there are more than 60 billion Java Virtual Machines (JVMs) running worldwide, making Java one of the most widely used development platforms.
Java enables you to run applications on different devices and platforms
Java applications run on a JVM, which is a software layer that interprets and executes Java bytecode. Bytecode is a compact and platform-independent representation of a Java program that can be transferred over the network or stored on a disk. The JVM translates bytecode into machine code that can be understood by the specific device or platform. This way, you can run a Java application on any device or platform that has a JVM installed.
Java offers security, performance, and compatibility features
Java has several features that make it secure, fast, and compatible. Some of these features are:
Security. Java has a built-in security model that prevents unauthorized access to system resources and data. Java applications run in a sandbox environment that isolates them from the host system. Java also supports encryption, authentication, and digital signatures to protect data transmission and storage.
Performance. Java has a just-in-time (JIT) compiler that optimizes the bytecode execution at runtime. Java also has a garbage collector that automatically manages the memory allocation and deallocation for Java objects. Java also supports multithreading, which allows multiple tasks to run concurrently on a single processor or multiple processors.
Compatibility. Java is compatible with both 32-bit and 64-bit browsers and operating systems. Java 46 bit is a version of Java that can run on both 32-bit and 64-bit systems, as long as they have enough memory and disk space. Java 46 bit can also run 32-bit Java applications without any issues.

Environmental variables are settings that affect how your system operates and interacts with other programs. To set environmental variables for Java on Windows, you need to follow these steps:
Open the Start menu and search for environment variables
To open the Start menu, you can click on the Windows icon on the bottom left corner of your screen or press the Windows key on your keyboard. To search for environment variables, you can type environment variables in the search box and press Enter.
This will show you a list of results related to environment variables. You need to select the option that says "Edit the system environment variables". This will open a window that allows you to edit your system's environmental variables.
Select the Edit the system environment variables option
In this window, you will see two tabs: Advanced and Remote. You need to click on the Advanced tab, which shows you the system properties of your system. You will see a button that says "Environment Variables" at the bottom of the window. You need to click on this button to open another window that shows you the environmental variables of your system.
Click on Environment Variables and edit the Path variable under System variables
In this window, you will see two sections: User variables and System variables. User variables are environmental variables that apply only to your current user account, while System variables are environmental variables that apply to all users and programs on your system. You need to edit the System variables section, which affects how Java runs on your system.
In the System variables section, you will see a list of variables and their values. You need to find the variable that says "Path" and click on it. This will highlight the variable and show you a button that says "Edit". You need to click on this button to edit the value of the Path variable.
Add the path to the Java bin directory and click OK
In the Edit environment variable window, you will see a text box that shows you the current value of the Path variable. The Path variable is a list of directories that your system searches for executable files, such as Java. You need to add the path to the Java bin directory to this list, which is where Java is installed on your system.
To add the path to the Java bin directory, you need to type a semicolon (;) at the end of the existing value and then type the path to the Java bin directory. For example, if you have installed Java in C:\Program Files\Java\jdk-16, then you need to type ;C:\Program Files\Java\jdk-16\bin at the end of the value. This will add the Java bin directory to the Path variable.
After you have typed the path, you need to click OK to save the changes. This will close the Edit environment variable window and take you back to the Environment Variables window.

How to Test the Java Installation on Windows
To test if Java is installed and working properly on your system, you can write and run a simple Java program using a text editor and a command prompt. Here are the steps to follow:
Write a simple Java program in a text editor and save it as Test.java
To write a simple Java program, you can use any text editor that you prefer, such as Notepad, Notepad++, Sublime Text, Visual Studio Code, or any other. You can also use an integrated development environment (IDE) such as Eclipse, NetBeans, IntelliJ IDEA, or any other.
A simple Java program that prints "Hello, World!" on the screen looks like this:
public class Test public static void main(String[] args) System.out.println("Hello, World!");
You can copy and paste this code into your text editor or IDE, or type it yourself. Make sure that you follow the syntax and spelling of Java, which is case-sensitive and follows certain rules and conventions. You can learn more about Java syntax and conventions [here].
After you have written the code, you need to save the file as Test.java in a folder of your choice. Make sure that the file name matches the class name in the code, which is Test in this case. The .java extension indicates that this is a Java source file.
Open a command prompt and navigate to the folder where you saved the file
To compile and run the Java program, you need to use a command prompt, which is a text-based interface that allows you to execute commands on your system. To open a command prompt, you can follow the same steps as before: press the Windows key + R on your keyboard, type cmd in the Run dialog box, and click OK. Alternatively, you can search for cmd in the Start menu and click on the Command Prompt app.
Once you have opened a command prompt, you need to navigate to the folder where you saved the Test.java file. To do this, you need to use the cd command, which stands for change directory. For example, if you saved the file in C:\Users\YourName\Documents\Java, then you need to type cd C:\Users\YourName\Documents\Java and press Enter. This will change the current directory to the one where the file is located.
Compile the program by typing javac Test.java
To compile the Java program, you need to use the javac command, which stands for Java compiler. This command takes a Java source file as an input and produces a Java bytecode file as an output. The bytecode file has the same name as the source file but with a .class extension. For example, if you compile Test.java, you will get Test.class as the output.
To compile the program, you need to type javac Test.java and press Enter. This will invoke the Java compiler and create the Test.class file in the same folder. If there are no errors in your code, you will not see any messages on the screen. If there are any errors, you will see them displayed on the screen and you will need to fix them before compiling again.
Run the program by typing java Test
To run the Java program, you need to use the java command, which stands for Java launcher. This command takes a Java bytecode file as an input and executes it on a JVM. You do not need to specify the .class extension when running a Java program, only the class name.
To run the program, you need to type java Test and press Enter. This will invoke the Java launcher and run the Test.class file on a JVM. If everything goes well, you will see a message saying Hello, World! on the screen. This means that your Java installation is successful and working properly.
