Introduction to Java Programming

• Host Introduction: Alex, with over 8 years of Java programming experience and a computer science degree.
• Purpose: Help beginners understand Java programming easily.

Basics of Programming

• Computers understand only zeros and ones.
• Programming languages (like Java) are created to simplify coding with keywords and symbols.

Setting Up the Java Environment

• Programming Environment: Use IDEs like Eclipse or IntelliJ to write and compile code.
• Creating a New Project:
  • Go to File > New > Java Project.
  • Name the project (example: "Java Tutorial Epicness").
  • Right-click on the source folder to create a new Java class.
  • Check the box for public static void main.

Storing Data in Java

Primitive Types

• Definition: Basic data types built into Java.
• Examples:
  • int a = 5; // Integer
  • char b = 'A'; // Character
  • long, double (other numeric types)

Non-Primitive Types

• String: Used to store sequences of characters.
  • Example: String name = "Susan";
  • Ends statements with a semicolon.

Methods in Java

• Calling Methods: Use a dot (.) to access methods of an object.
  • Example: name.toUpperCase();
• Creating a Method:
  • Syntax: public static void addExclamation(String s) { ... }
  • Use return for methods that output a value.

Object-Oriented Programming (OOP)

• Definition: Java is an object-oriented programming language.
• Classes: Java files representing objects.
  • Example: Creating an Animal class with a method IAmDog().
• Using Objects:
  • Create objects with Animal a = new Animal();.
  • Call methods with a.methodName();.

Logic in Java

If Statements

• Format: if (condition) { ... }
• Multiple conditions can be handled with else if and else.

Loops

• For Loop:
  • Syntax: for (initialization; condition; increment) { ... }
• While Loop:
  • Syntax: while (condition) { ... }

Exception Handling

• Try-Catch: Handles exceptions in code.
  • Syntax: try { ... } catch (Exception e) { ... }

APIs in Java

• Definition: APIs are collections of methods provided by other software.
• Using an API: Download the jar file and import it into your project.

Summary

• Covered:
  • Primitive types, variables, storing data.
  • Objects, classes, methods, logic statements, and symbol meanings.
