Specialization in Java: Part I - For Beginners.

Learn how variables store and access data in memory, use variable names as addresses, and how data types like short, long, float, double, char, and boolean enforce typing in Java.

Explore the atomic elements of Java—identifiers, literals, keywords, and operators, and how variables are declared with names, types, and optional initializers. Understand tokens, whitespace, comments, and terminators.

Declare and initialize variables in a Java class with a main method, print their values, and understand assignments, scope, and blocks.

Explore type conversion and casting in Java, including widening and narrowing conversions, automatic and explicit casting, and how integers, characters, and booleans are stored as binary in memory.

Learn how arithmetic operators in Java perform addition and math operations, and how the plus operator concatenates strings. Grasp left-to-right evaluation, type promotion, and handling of numbers, characters, and strings.

Explore the remaining arithmetic operators in Java, including subtraction, multiplication, division, and modulus, along with assignment operators and increment/decrement in prefix and postfix forms.

Explore bitwise operators in Java, including not, and, or, and xor, and learn how they manipulate binary patterns to transform integers at the bit level.

Explore bitwise operators in Java by applying not, and, or, and xor to variables, computing results in a main method, and printing outcomes.

Learn how bitwise operators in Java work, including left and right shifts, unsigned right shift, and sign-aware behavior, plus how complement encoding represents negative numbers.

Utilize Java's six relational operators to compare values and yield boolean results. Learn how equality and relational forms—==, !=, >, <, >=, <=—are used in if statements and loops.

Explore boolean logic operators in java, including and, or, xor, and not, and the short-circuit versions of and and or, plus how relational operations yield boolean values.

Explore if-else statements and taking input from the user in Java, using the Scanner to read integers, and creating objects to control program flow with boolean conditions.

Learn how to take input from the user in Java using the Scanner, with nextInt and nextDouble, handle input mismatch exceptions, and understand automatic type conversion from int to double.

Learn to write a Java program that reads a user number, uses the modulus operator to test divisibility by 2, and prints even or odd via if statements.

Teach a beginner Java program to play rock, paper, scissors against the computer, using a random move and a scanner for user input with options 1, 2, or 3.

Use the random class to generate a number from 0 to 2, add 1 to map it to 1-3, and let the computer choose rock, paper, or scissors.

Develops the game logic for rock-paper-scissors by reading user input, generating a random computer choice, and evaluating outcomes with conditional statements.
