What is Java?
// It is a high-level programming language primarily used for building powerful and scalable applications.
// It emphasizes the use of classes and object as it works on Object oriented Programming.
// For your better understanding giving a simple java program that prints "Hello, IIHT!" to the console:
// Define a class named HelloIIHT
class HelloIIHT {
// Define the method, which will work as an entry point
public static void main(String[] args)
{
// Print "Hello, IIHT!" to the console
System.out.println("Hello, IIHT!");
}
}

Getting Started With Java
1. Step one is to install the Java Dev. Kit :
- Click here or here to download the Java Development kit.
- Now select an appropriate Java version for your operating system and download the installer.
- Install and run the downloaded file to start.
2. Set up the Java Development Environment :
- Start by setting JAVA_HOME to the directory where the Java Dev. Kit was installed.
- Add Java Dev. Kit’s bin directory as your system’s PATH environment variable.
- Verify your installation by opening a terminal/command prompt and running the command java -version. The Java version should be displayed.
3. Choose an Integrated Development Environment (IDE) :
- IDEs provide powerful tools for Java development, a. including code editing, debugging, and project management. A few Popular options include, a. Eclipse, IntelliJ IDEA, and NetBeans.
- Select one IDE and complete the setup by downloading and installing it, ref. Their respective websites for installation related instructions.
4. Create a Java project :

//"Hello, World!" program:
public class Class {
public static void main(String[] args){
System.out.println("Hello, World!");
}
}
6. Develop a program and run it :
- Get use of your IDE’s build or compile command to compile your Java code.
- In case there are NIL syntax errors, you can also run your program inside the IDE.
- Once you run the program verify your output as Running “Hello, World!” in the output console.
