Java for Beginners - Learn all the Basics of Java

Create your first Java project, define a public class with a main method, and print Hello World using System.out.println, then run and view the result.

Explore the three data type categories in Java—boolean, char, and numbers—and learn how range and memory usage affect performance, choosing types such as byte, short, int, long, float, and double.

Learn how to create and use variables in java by exploring primitive data types, booleans, characters, and strings, and printing values with system.out.

Master basic Java arithmetic by using doubles and variables to perform addition, subtraction, multiplication, and division, and print results.

Learn to use the Java Scanner to read strings from the user, import the scanner, and echo the input back, building basic user interaction in Java.

learn how to use the Scanner in Java to read user input as strings, numbers (double) and booleans, and convert between them with nextDouble and nextBoolean.

Explore Java operators, including comparing operators (==, !=, >, <, >=, <=) and logical operators (and, or, not), with practical examples to build foundational programming skills.

Learn to compare numbers, booleans, and strings in Java using equality, inequality, and logical operators; test conditions and print results with example variables.

Explore the basics of the if function in Java, including if, else, and else if statements, to execute code based on conditions and return different results, with practical pizza examples.

Practice and explain the if function in Java by testing conditions with numbers and strings using doubles, and chaining else if and else to handle multiple scenarios with System.out.println outputs.

Learn to build a Java console app using strings and a scanner with if statements to ask users if they want a car and to choose red, blue, or yellow.

Build a car selector flow using if and else if statements, with nested ifs, to respond to red, blue, yellow, or other colors. Check stock, prompt to see or order.

Learn how to store data in Java using arrays, including doubles and strings, organize variables in an array, and use basic if statements and printing with system out.

Learn the basics of loops in Java, including for and while loops, with a brief note on do-while, to repeat code and solve algorithmic problems through controlled iterations.

Explore the basics of for loops in Java by building a simple loop from 0 to 14, experimenting with increment steps, data types like double, and avoiding string additions.

Practice building a simple Java app that uses arrays and strings to store car colors, iterate with a for loop, and check colors with if/else, printing results.

Build a Java GPA converter by collecting course grades with a scanner, storing them in an array, computing the average with a for loop, and mapping to letter grades.

Create a basic test using a while loop to ask questions, retry on wrong answers, and move to the next question, like two plus two in letters.

Explore Java collections, including lists and maps, as a framework of interfaces and classes that support searching, sorting, insertion, and deletion, with implementations like hash maps and linked hash maps.

Learn how to create and manipulate a Java list of strings using ArrayList, performing add, remove, set, get, size checks, and clear operations.

Create and manipulate hash maps in Java using keys to store car stock. Learn common operations like add, remove, size, and get, and see how maps differ from lists.

Explore the basics of classes and objects in Java, treating a class as a blueprint for objects that encapsulate data and behaviors, with practical car examples.

Build a complete Java console application from scratch, implementing password creation, authentication with a while loop, and a basic food-order flow using a scanner.

Students advance the final project by implementing password security, prompting hunger input, storing answers, and validating choices with if/else and a while loop to pick pizza, burger, or fish.

Develop a basic interactive flow that verifies user choices among pizza, burger, or fish using while and if statements, retrying until valid input and then asking about a drink.

Develop Java basics by building a final project flow with input validation through if statements and while loops, handling yes/no prompts, drink orders, and password verification.

Final project part 5 guides students to implement an else branch in a Java if statement, handle order scenarios, password validation, and basic testing to verify an interactive menu app.

Solidify your Java basics with hands-on projects that cover statements, loops, and variables, and learn to create small applications through daily practice.
