Computational Thinking

A way of solving problems by breaking them down into smaller steps, spotting patterns, & creating clear instructions that a computer ( or person ) can follow

Algorithm

A step - by - step set of instructions to solve a problem.

Abstractions

Focusing only on relevant details of a problem & ignoring irrelevant information.

Decomposition

Breaking down a complex problem into smaller parts.

Pattern Recognition

Finding similarities/patterns in a problem

Class

A blueprint (set of instructions) used to create objects in Java (e.g., Spider, Fly )

Object

An instance (version) of a class (e.g., a specific fly in the world)

Instantiation

Term for creating an instance of a class

Inheritance

Inheritance means one class can get features ( properties & methods ) from another class.

For loop

if/else statements

Used for decision-making in code.

If statement is used to make decisions.

Else statement is used to specify a block of code to be executed if a given condition is false.
