Introduction ​

Java Installation: ​

Before you start coding in Java, you need to install the Java Development Kit (JDK) on your system. You can download the latest version of JDK from the official Oracle website (https://www.oracle.com/java/technologies/javase-jdk16-downloads.html) and follow the installation instructions for your operating system.

Java Development Kit (JDK) vs. Java Runtime Environment (JRE): ​

• JDK: The Java Development Kit is a software development environment used for developing Java applications. It includes the Java compiler (javac), debugger (jdb), and other development tools, along with the Java Runtime Environment (JRE).
• JRE: The Java Runtime Environment is a software package that provides the necessary runtime components to run Java applications. It includes the Java Virtual Machine (JVM) and the Java class libraries.

Setting Up Java Environment: ​

After installing the JDK, you need to set up the Java environment variables on your system to compile and run Java programs. The steps for setting up the environment variables vary based on the operating system you are using.
