Java Installation

 

I am thrilled to share some insights about Java and the installation of Java. The first step is getting your Java Development kit set up. (JDK) The JDK provides everything that is needed to write, compile and run java applications. Some helpful links to get started with are: https://docs.oracle.com/javase/tutorial/getStarted/cupojava/index.html This site from Oracle gives tips as well as step by step tutorials as well as links to download java. Be careful to download the correct installation pack. It’s based on your operating system. For example, windows users will need to download the one for Windows. Another similar site that gives a breakdown of step by step set up and installation is Programiz Java HelloWorld program. https://www.programiz.com/java-programming/hello-world If you are like me and still find yourself confused AI is a wonderful teacher. I used Googles Gemini when setting up Java. What I like about Gemini is I was able to share screenshots and get step by step instructions and encouragement. https://gemini.google.com/

Now that you have installed Java let’s learn a little about it. Java adheres to object-oriented design. (OOD) It’s a way of thinking about software development that models real world entities as objects. There are four pillars.

Encapsulation: The secure package

Abstraction: Focusing on what matters

Inheritance: Building on existing foundations

Polymorphism: One interface, many forms

OOD allows complex problems to be broken into smaller and more manageable objects, it leverages existing code, enhances maintainability and allows for scalability. Understanding OOD and the four pillars will help in the Java journey with writing code.
