Java If … Else

if and else statements are used in Java to make decisions based on conditions. They allow the program to execute different blocks of code depending on whether a condition is true or false.

✅ Basic Syntax

🧠 Example

`if` Statement Only

Sometimes you may only need an if without else:

`if ... else if ... else`

Used when there are multiple conditions to check.

Nested `if` (if inside another if)

Short If (Ternary Operator)

A shorter way to write an if-else statement.

⭐ Full Example

public class Main {
public static void main(String[] args) {

int temperature = 30;

if (temperature > 35) {
System.out.println("It's very hot!");
} else if (temperature > 20) {
System.out.println("Weather is pleasant.");
} else if (temperature > 10) {
System.out.println("It's cold.");
} else {
System.out.println("Very cold weather.");
}
}
}

public class Main {

public static void main(String[] args) {

int temperature = 30;

if (temperature > 35) {

System.out.println("It's very hot!");

} else if (temperature > 20) {

System.out.println("Weather is pleasant.");

} else if (temperature > 10) {

System.out.println("It's cold.");

} else {

System.out.println("Very cold weather.");

}

📌 Summary

Structure	Use Case
`if`	Executes only when condition is true
`if...else`	Runs one of two code blocks
`else if`	Multiple conditions
Nested if	Decision inside another decision
Ternary `?:`	Short version of if/else
