Java Control Flow (If, Else, and Switch)

Control flow statements in Java allow you to control the execution of your code based on certain conditions.

If-Else Statement

public class ControlFlowExample {
    public static void main(String[] args) {
        int age = 20;

        if (age >= 18) {
            System.out.println("You are an adult.");
        } else {
            System.out.println("You are a minor.");
        }
    }
}

This program uses an if-else statement to check if the user is an adult or a minor based on their age.

Switch Statement

public class SwitchExample {
    public static void main(String[] args) {
        int day = 3;

        switch(day) {
            case 1:
                System.out.println("Monday");
                break;
            case 2:
                System.out.println("Tuesday");
                break;
            case 3:
                System.out.println("Wednesday");
                break;
            default:
                System.out.println("Invalid day");
        }
    }
}

This example demonstrates the use of a switch statement to print the day of the week based on the value of day.
