[KNCMAP-TECHNOLOGIES]

Here is the notes

package com.myapppublish.helloworld
//package defines the namespace or the package in which the class or files reside
//its away to group related classes together
//it should match the directory structure in your project.
//TIP To <b>Run</b> code, press <shortcut actionId="Run"/> or
// click the <icon icon in the gutter.
//org.example this would be the package name or the package name the classes or functions are part of
//fun main() {
// println("Hello world")
//println(1233)
//}
//fun is a keyword used to declare a function.
//main() is a function any code inside the {} will be executed
//println("string") is a function inside the main() Function
fun main(args: Array<String>) {
println("Hello world!")
println("Hello KNCMAP-TECHNOLOGIES!")
println("It's a kotlin class")
println(3+3123456723456789)
val pi = 3.14//val can't be modified thus we use it here
var radius = 20//var can be modified radius can be dynamic
var area = pi * radius * radius
println("this is pi: $pi radius: $radius area: $area")
var strings = "string"
println(pi)
println(strings)
var x=12
var y=13
var _uii=900
println(x+y)

}
/*parameters args is a parameter of type Array<String> it's used to pass commandline
arguments to the program */
//Array<String> this means args will hold any string that are passed when you run the program
//print("it\'s a python class")
//multiline comment /* your comment */
//your comment here
// var and val
//var is a variable that can be changed
//val is a variable that can't be changed
//camel case var myNameField = "Goes here"
//pascal case var MyNameField = "Goes here"
//snake Case var my_name_field = "Goes here"
//int, double, char, boolean, string
