Java programming language - JAVA for BEGINNERS course

Configure the ide for a new Java project by selecting a JDK, naming the project, and applying appearance and behavior settings, including unambiguous imports, optimize imports, and code folding options.

Create your first java project and a hello world class, name the project and class correctly, explore the project structure and code editor, and tackle the my first program challenge.

Learn what a class is in Java, using a notebook analogy, and discover curly brackets and how public (with private and protected) controls who can see your code.

Explore storing data in variables in Java by declaring and initializing a variable, using memory boxes to track type, name, and values, and updating one place to change all text.

Learn how binary and decimal systems encode numbers, what a bit is, and how variable size and type define memory usage and data in Java.

Learn the four integer storage options: byte, short, int, and long, their bit sizes and ranges, and how to append L for long literals.

Explore working with integers in Java through variable initialization, arithmetic operations such as addition, subtraction, and division, and printing results, using apple baskets and budgets to illustrate fractions.

learn how to store fractional numbers with float and double in Java, and decide when to use each for memory efficiency versus precision.

Master boolean in Java by understanding true or false as logical values, and review the eight primitive variables, including short, long, float, double, char, boolean, and the string.

Create the project, define a class, create a scanner, and declare variables for input and conversion. Then assemble the final message and note the small error at the beginning.

Start a new Java project by creating a class and main method, set up a scanner for user input, perform a calculation, and display the result message.

Start by creating a new Java project and a class named Hello World, following naming conventions with capitalized class names, and explore the project structure and code editor.

Learn how to use Java comments, including // for single lines and /* ... */ for blocks, and how backslash escape handles quotes and newlines in strings.

Learn how if statements in Java control program flow by executing code only when a condition is met, using boolean and numeric examples and the standard syntax.

Apply if statements to execute code when conditions are met and provide feedback when they are not, such as printing pass or fail messages and using else for outcomes.

Discover how to use else if within chained if statements to assign grades from a score, and watch the compiler evaluate conditions from top to bottom.

Learn relational operators in Java by building conditions with numbers, booleans, and strings using equals method for string comparison. Connect conditions with or and and to require one or both criteria.

Explore nested if statements in java by stacking conditions inside the first if, using booleans for movie on tv, watched status, and review rating.

Master loops in Java by coding repeated actions until a condition holds, using for, while, and do while loops with clear, practical examples.

Explore the while loop with practical examples that increment variables, apply if statements, and print results. Repeat the loop while conditions hold, as shown with golden fish wishes scenario.

Master the for loop by initializing a control variable, defining a condition, and updating it each iteration, with countdown examples showing how many times it runs.

Explore the do-while loop in Java, which runs at least once before checking the condition. Compare it to a standard while loop with password and email examples.

Learn how break and continue control loops in Java. Use a guessing game to show break exits a loop and continue restarts the for loop for new iterations.

declare an array by specifying the type and name, create it with new, and define its elements; use zero-based indexing to populate and access items, and loop to print.

Learn how to return values from Java methods by using the return keyword and specifying a return type. See practical examples like converting dollars to euros and calculating averages.

Java is an object oriented language where objects, like tables and dogs, are created from classes that act as blueprints, defining objects with variables and methods.

Create a Java project, define a dog class with name, breed, age, and color, and instantiate a dog object in the main method to access its attributes.

Learn how private instance variables are accessed in Java using public getters and setters, enabling controlled setting and retrieving of values in a class.

Explore constructor overloading in Java by creating multiple constructors with different parameters, assign default values with this, and understand how the compiler selects the right constructor.
