3.3 If Else Statements

Purpose of Else Statements

Else statements: Handles what happens when the if condition is false. Structure of If-Else:

• If statement with a condition.
• Else statement without a condition.
• Both parts have code blocks surrounded by {}.

don’t forget the brackets

if (x > 10) {

        console.log("x is greater than 10");
        console.log("This code when the condition is true");
    } else {
    
        console.log("x is 10 or less");
        console.log("This code runs when the condition is false");
    }
    Without brackets:
    
    if (x > 10)
    
        console.log("x is greater than 10");
        console.log("this code will always run");

1. Based on this code, if you were younger than 16 what would it print out?

2. Write your own if else statement

3. You are not old enough for a license yet.

// 2. 

int heightInch = 70; 
System.out.println("Your height in inches is " + heightInch);
if (heightInch >= 60) {
    System.out.println("You are tall enough to ride the roller coaster");
} else {
    System.out.println("You are not tall enough to ride the roller coaster");
}

Your height in inches is 70
You are tall enough to ride the roller coaster
