Java And C++ And PHP Crash Course All in One For Beginners

Create and run a Java hello world program in Eclipse by building a project, package, and class, writing a main method, and printing hello world to the console.

Learn how Java arithmetic operators work with integers by using a scanner to take keyboard inputs for A and B and perform addition, subtraction, multiplication, division, and modulus.

Explore Java unary operators with practical examples, including minus unary, post and pre increment, and their effects on part one, part two, and boolean outputs.

Explore Java bitwise operators through practical examples using byte values 12 and 10, including not (~), and &, xor (^), left shift, and right shift, plus explanations of two's complement.

Demonstrates relational operators in Java using a boolean result, showing ==, <, <=, >, >=, and != with true or false outcomes.

Explore how Java's conditional operators work by illustrating boolean variables with or (||) and (&&) operators, showing true or false results.

Explore how to create and manipulate strings in Java, using character arrays, the string constructor, direct assignment, the plus operator for concatenation, and user input with scanner.

Explains how to use Java string methods to manipulate and compare text, including length, equals, equalsIgnoreCase, charAt, startsWith, endsWith, indexOf, lastIndexOf, replace, substring, split, and trim.

Explore string buffer and string builder in Java, demonstrating capacity handling, constructors, and append, insert, and reverse operations to efficiently manage and manipulate strings.

Demonstrates how the java static keyword creates a single shared variable across objects, contrasts it with non static fields, and shows static methods access only static variables.

Create a student class with name, ID, and major; instantiate objects, initialize fields with setter methods, and display them.

Explore the Java boolean datatype by declaring a boolean variable, assigning true and false, printing results, and understanding type mismatch errors when using an int.

Learn to handle Java character type data by declaring a character variable, initializing it with capital A in single quotes, and printing its value, including Unicode hexadecimal 0041.

Explore Java inheritance by modeling an employee, developer, and tester with a protected salary and bonuses, showing how derived classes access inherited fields and compute total salaries.

Learn the basics of php syntax, write a hello world program using php tags, and run it from the command line, ensuring the php executable is in your path.

Explore PHP file input output by writing to a new file with fopen in write mode and fwrite, then read with fopen in read mode and feof until end-of-file.

Explains PHP assignment operators, including plus-equals, minus-equals, star-equals, divide-equals, and mod-equals, using A=42, B=20, and a running C to illustrate cumulative updates and results.

Explore PHP comparison operators with A and B, testing equal, not equal, greater than, and less than. Evaluate greater than or equal to and less than or equal to.

Demonstrate how to run a hello world PHP script within an HTML page on a PHP-enabled server by saving it to the document root and visiting localhost/hello.php.

Learn web concepts with PHP by comparing client-side and server-side scripts, showing how JavaScript displays the client date and PHP echoes the server date.

Learn how the break statement in PHP terminates loops and switches, enabling early exit when a condition is met, as shown with a while loop generating random numbers.

See how the PHP continue statement works inside a while loop: it restarts the next iteration and skips remaining statements when a condition, such as x equals five, occurs.

Master PHP console input output by reading integers from standard input with fscanf and displaying the computed area to standard output using printf, via the command prompt.

Explore PHP for loops through three examples: a basic counting loop with initialization, test condition, and increment; a random-terminated loop using rand; and an array traversal loop.

Demonstrate PHP's while loop with two examples: a deterministic loop counting from 1 to 10, and a random loop that repeats until a generated number equals five.

Learn how PHP switch case replaces many if statements by using rand to generate numbers and select addition, subtraction, multiplication, or division, with break to prevent fall-through.
