Java is a popular object-oriented programming language that was created in the mid-1990s by Sun Microsystems. It was designed to be portable, meaning that code written in Java can run on any platform that has a Java Virtual Machine (JVM) installed, without needing to be recompiled for that platform.
Java is commonly used to develop desktop applications, web applications, mobile applications, and enterprise software. Its syntax is similar to that of C++ and C#, but with some key differences, such as the use of garbage collection to automatically manage memory allocation and deallocation.
1. Object-oriented programming
2. Platform independence
3. Garbage collection
4. Exception handling
5. Multi-threading
To get started with Java programming, you'll need to install the Java Development Kit (JDK) on your computer, which includes the Java compiler, the Java Virtual Machine (JVM), and other tools. Once you have the JDK installed, you can use an Integrated Development Environment (IDE) such as Eclipse or IntelliJ IDEA to write, debug, and test your Java code.
1. Open a text editor or your favorite Java IDE.
2. Type the following code: typescriptCopy code public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } }
3. Save the file as HelloWorld.java.
4. Open a terminal or command prompt and navigate to the directory where you saved the file.
5. Compile the program by running the command javac HelloWorld.java.
6. Run the program by running the command java HelloWorld.
This will output "Hello, World!" to the console. From there, you can start exploring Java's syntax, object-oriented features, and built-in libraries to develop more complex programs.
