I downloaded Java here:
And then i am using Intellij IDE from Jetbrains.

I wrote my first Java program 2 days ago. I am doing this with the #100DaysOfCode on Twitter. To track my progress.
What i have learnt so far.
- Every Java program must have at least one function.
- The functions don’t exist on their own. It must always belong to a class.
- A class is a container for related functions.
- Every Java program must have at least one Class that holds the main function
- Then we need Access modifiers in Java.
What are access modifiers?
They help set boundaries to the scope of a class, constructor , variable, or method.
For my first Java program. I will only be interested in the "Public" access modifier.
package com.codewitedison;
public class Main {
public static void main(String[] args) {
System.out.println("Welcome to my first Java Program);
}
}
Intellij makes it really easy. So it came with the Java boilerplate that set the public class main and the public static void main lines. I only added the System.out.println and print message. System.out is a way to print results to the terminal.
