Mastering Kotlin for Absolute Beginners

Learn how to declare Kotlin variables with var, assign values like 25 and 30, and enforce types such as int, double, and string, then print results and observe compile checks.

Practice variables in kotlin by declaring names with underscores, avoiding spaces, and setting types with var. Learn printing values and using escape sequences for new lines.

Learn how to use Kotlin comments (single-line, multi-line, and doc comments), distinguish val versus var (immutable vs mutable), and build string templates with dollar sign substitutions.

Explore how to get user input in Kotlin, convert strings to double and int, print results with string templates, and perform arithmetic using readLine and variable manipulation.

Master comparison operators in Kotlin, including greater than, less than, equal to, greater than or equal to, less than or equal to, and not equal to, with boolean results of true or false.

Master the for statement in Kotlin by iterating over languages and collections, printing each item, and comparing its behavior to the while loop across arrays, maps, and ranges.

Explore nested loops in Kotlin by using a for loop inside another to print multiplication tables from 2 to 10 and 1 to 10, with star separators.

Master the continue statement to skip specific iterations and the break statement to stop loops, with labels guiding targeted continue.

Learn how to use Kotlin arrays, fixed-size collections of numbers; index, loop, print, and modify items, and recreate arrays to add elements.

Master Kotlin functions by using the fun keyword, defining parameters and a string return type, and printing messages such as hello name or goodbye.
