Module 2: Data Types, Variables, and Type Casting

This is the "Syntax Foundation."

1. Primitive Data Types Java is strictly typed. There are 8 primitives:

• Numeric Integral: byte (1 byte), short (2 bytes), int (4 bytes), long (8 bytes).
• Numeric Floating: float (4 bytes), double (8 bytes).
• Character: char (2 bytes - Unicode).
• Boolean: boolean (size depends on JVM, holds true/false).

2. Variables

• Local Variables: Declared inside methods; must be initialized before use; stored in the Stack.
• Instance Variables: Declared inside a class but outside methods; stored in the Heap; have default values.
• Static Variables: Declared with static keyword; shared by all objects; stored in the Method Area.

3. Type Casting

• Implicit Casting (Widening): int to double. Safe, done automatically.
• Explicit Casting (Narrowing): double to int. Risky, data loss possible, must be done manually.

4. Critical Analysis (Pros & Cons)

7.4 Date & Time API (Java 8)

• Why replace java.util.Date? Immutability and thread-safety.
• LocalDate, LocalTime, LocalDateTime (No timezone) vs ZonedDateTime.

1. Java Basics

• Variables, Data Types, and Operators: Understanding the basic data types, operators, and variables.
• Control Structures: if-else statements, switch statements, loops (for, while, do-while).
• Methods and Arrays: Understanding how to define and use methods, and working with arrays.

4.4 Inter-Thread Communication

• wait(), notify(), notifyAll(). The notes explicitly state: These must be called from a synchronized context (inside synchronized block), otherwise IllegalMonitorStateException.
