JAVA Immersive Learning Course

Explore if, else if, else control flow with input via next line and char conversion. Use equals and not equals, parse doubles, assign grades, and track a running student count.

Explore printf formatting in Java, including leading zero padding, width and precision with %f, %d, and %s. Understand how right and left justification affects output.

Explore the Java random class by creating a random object and using nextInt and nextDouble. Apply a binary search to guess numbers and note cryptographically secure alternatives in Java.

Explore practical problem solving by transforming tasks, comparing approaches, and writing efficient for loops—from checking squares and generating fibonacci sequences to pruning cases and reducing time complexity.

Demonstrate building bigger functions from small ones by computing the expected value, average, standard deviation, and skewness for a numeric array, using for loops and powers.

Explore how a class defines a concept and how to create objects, using a square to demonstrate set side, get area, and get side via the dot operator.

Learn how constructors initialize private variables and objects like square, circle, and rectangle, including default and parameterized forms and constructor overloading.

Return an array from a function and print powers of two with an enhanced for loop, demonstrating arrays and functions that can return multiple values.

Explore an array of objects using a circle class with radius, constructors, getters, and setters. See how each element points to a circle object, enabling radius access, modification, and area.

Learn to build a Java program that outputs words backwards by transforming a string into a char array and reconstructing it in reverse, then converting back to a string.

Learn to evaluate polynomials by plugging in x and summing coefficients times powers of x via an array. Then add polynomials by aligning coefficients and padding with zeros.

Explore how to test palindromes in java by converting strings to char arrays and comparing mirrored characters, with examples like abba and taco cat.

Discover insertion sort and selection sort on arrays, tracing how to find the minimum, swap elements, and use nested for loops to sort.

Explore how to compute n choose k using factorials, recursion, and Pascals triangle, and how to generate every combination by representing choices as binary numbers and converting them to code.

Review of classes covers Java basics: packages, blueprints, private fields, constructors, this keyword, getters and setters, object instantiation, and simple methods like area, plus a student class with grades handling.

Explore how to implement a copy method and a copy constructor in a circle class to create a new object with the same radius and name.

Shows how to model a car with enum types for make and color, implement getColor, getType, and toString, and use a switch to handle different makes like Ferrari.

Model a sandwich with a bread object, illustrating has-a aggregation relationship, default and parameterized constructors, and methods to reveal bread style, filling, and fall status.

Strings are immutable in Java, creating new objects for changes. Use the StringBuilder to efficiently build strings with append, insert, and replace, offering extra methods and security benefits.
