Master apex if-else logic by comparing two integer ages to decide who is older, illustrated with ages 28 and 30 and 38 and 30, and outputs via system debug messages.

Learn how the if else if ladder works in Apex by evaluating multiple conditions from top to bottom, executing the first true block and defaulting to else when all fail.

Learn how to implement an Apex if-else-if ladder to classify a number as positive, negative, or zero using a sample with System.debug outputs.

Explore if else if logic in apex with a race medal example, assigning gold, silver, bronze, or no medal based on place, and printing results via debug statements.

Explore Apex switch statements in Salesforce development for beginners, learn how switch on expression tests values against multiple cases with optional default else blocks, and compare to if-else constructs.

Demonstrates a switch statement example on an integer num initialized to -3, showing cases for 2 and -3 and a default block that prints the corresponding message.

Explore how to use a switch statement in Salesforce Apex to map race places to medal colors (gold, silver, bronze), handle nulls, and display outcomes with debug messages.

Discover how Apex switch statements support multiple values in when clauses, using comma separated values, with first, second, and third place blocks plus an else clause and duplicate value errors.

Learn what expressions are and what statements are, why semicolons end statements, and how whitespace and indentation improve readability for beginners.

Explain how Apex loops work to repeat instructions while a boolean condition stays true, covering while, for, and do-while loops with practical examples and syntax.

Learn how to use a while loop in Apex to display 1 through 10, with a counter, condition, and various increments and a reverse option.

Learn how for loops in Apex simplify looping by combining initialization, condition, and increment in one line, contrasting with while loops. See a practical example that prints 1 through 5.

Learn how to use a for loop in Salesforce to calculate salary after bonuses of 5, 10, 15, and 20 percent, including the step-by-step calculation and debug output.

Explore how to implement a for loop in Apex with a practical countdown example from ten to zero by two, covering initialization, condition, and decrement steps.

Define an infinite loop in Apex, show why it triggers a CPU time limit exceeded error, and explain how to avoid it by enforcing an end condition.

Explore Apex for loop variations, including the traditional for loop and the list or set iteration for loop, and learn how lists handle duplicates while sets do not.

Compare break and continue statements in Apex loops, showing how break exits the loop when a condition is met, while continue skips a single iteration and continues the loop.

Demonstrate nested loops by placing a loop inside another, with an outer loop from 0 to 3 and an inner loop from 0 to 2 that prints A and B.

Explore nested loops that generate a triangular sequence: outer loop 1–4 with an inner loop printing the outer value, yielding 1 2 2 3 3 3 4 4 4 4.

Demonstrate how nested for loops generate patterns by printing 1, then 1 2, then 1 2 3, and 1 2 3 4 using an outer loop and an inner loop.

Treat a class as a blueprint and an object as a memory-resident instance. Use new to create objects, reference variables to control them, and distinguish non-static from static methods.

Create an employee class with name and designation fields, then instantiate two objects to demonstrate instance variables and a non-static show method that displays each employee’s details.

Explain static and non static methods in Apex, showing how static methods are called via the class name while non static methods require an object in a simple Apex class.

Explore static and non-static variables: non-static have per-object copies, while static shares a single class variable across all objects. Access static variables via the class name and note cross-object effects.

Learn about access modifiers in apex by building a cat class with private variables and public methods to set the name and size and prevent wrong values.

Explore constructors in Apex to initialize object fields like name and size. Learn how default and parameterized constructors set values, as shown by Scooby 13 and Tina 10.

Explore how to create and manipulate lists in Apex, including array notation, constructors, and the add method, and learn to access elements by index and determine list size.

Compare set and add on a list of integers: set replaces the element at an index; add inserts a new element at that index, shifting subsequent items.

Learn how to debug incompatible collection type errors by exploring lists of strings and integers, understanding type safety, and using add operations and line number clues to fix type mismatches.

Sort lists in Apex by using the sort method, arranging integers in ascending order and strings alphabetically, as demonstrated with color lists and numeric examples.

Learn maps as key-value pairs by defining primitive keys and values, storing employee ids and addresses, and using get, put, size, and clear to manage entries.

learn how maps handle duplicate keys and duplicate values; keys cannot be duplicated, and assigning a new value to an existing key overrides the old one while values may repeat.
