# Week 1 – Setup, Java Basics, Primitive Data Types & Variables
2+
3+
---
4+
5+
## Why Learn This?
6+
7+
Understanding Java’s syntax and primitive data types is like learning the alphabet before writing words. This foundation enables you to:
8+
9+
* Build reliable, efficient programs.
10+
* Understand how Java communicates with your machine.
11+
* Begin thinking like a software engineer.
12+
These basics also make it easier to learn advanced Java concepts later and transition to other languages.
13+
14+

15+
16+
## Week 1 Concepts & Notes
17+
18+
### Java Setup
19+
20+
* Install the **Java Development Kit (JDK)**.
21+
22+
* Use **Command Line (CLI)** to compile and run Java programs:
23+
24+
```bash
25+
javac HelloWorld.java
26+
java HelloWorld
27+
```
28+
29+
* Use an **IDE like IntelliJ** for easier development.
30+
31+
### Your First Java Program
32+
33+
```java
34+
public class HelloWorld {
35+
public static void main(String[] args) {
36+
System.out.println("Hello, world!");
37+
}
38+
}
39+
```
40+
41+
* `public static void main(String[] args)` is the program entry point.
42+
* `System.out.println()` prints to the console.
43+
44+
### Comments
45+
46+
```java
47+
// This is a single-line comment
48+
49+
/* This is
50+
a multi-line comment */
51+
```
52+
53+
### Primitive Data Types
54+
55+
| Type | Description | Example |
56+
| --------- | ----------------- | ------------------------- |
57+
| `int` | Integer numbers | `int x = 10;` |
58+
| `double` | Decimal numbers | `double y = 3.14;` |
59+
| `boolean` | True/False values | `boolean isTrue = false;` |
60+
| `char` | Single characters | `char letter = 'A';` |
61+
62+
### Variables
63+
64+
```java
65+
int age = 30;
66+
double price = 19.99;
67+
char grade = 'A';
68+
boolean isValid = true;
69+
```
70+
71+
### Type Casting
72+
73+
```java
74+
int a = 10;
75+
double b = a; // implicit casting
76+
int c = (int) b; // explicit casting
77+
```
78+
79+
### Input & Output
80+
81+
```java
82+
import java.util.Scanner;
83+
84+
public class InputExample {
85+
public static void main(String[] args) {
86+
Scanner scanner = new Scanner(System.in);
87+
System.out.print("Enter your name: ");
88+
String name = scanner.nextLine();
89+
System.out.println("Hello, " + name);
90+
}
91+
}
92+
```
93+
94+
### Operators
95+
96+
#### Arithmetic Operators
97+
98+
```java
99+
int x = 10 + 5; // 15
100+
int y = 10 - 3; // 7
101+
int z = 2 * 3; // 6
102+
int a = 10 / 2; // 5
103+
int b = 10 % 3; // 1 (remainder)
104+
```
105+
106+
#### Relational Operators
107+
108+
```java
109+
int a = 5;
110+
int b = 10;
111+
boolean result = a < b; // true
112+
```
113+
114+
#### Logical Operators
115+
116+
```java
117+
true && false // false
118+
true || false // true
119+
!true // false
120+
```
121+
122+
---
123+
124+
### Conditional Statements
125+
126+
```java
127+
int score = 85;
128+
129+
if (score >= 90) {
130+
System.out.println("A");
131+
} else if (score >= 80) {
132+
System.out.println("B");
133+
} else {
134+
System.out.println("C or below");
135+
}
136+
```
137+
138+
#### switch Statement
139+
140+
```java
141+
int day = 3;
142+
143+
switch (day) {
144+
case 1:
145+
System.out.println("Monday");
146+
break;
147+
case 2:
148+
System.out.println("Tuesday");
149+
break;
150+
default:
151+
System.out.println("Other day");
152+
}
153+
```
