Else

When you want to do one thing when a condition evaluates to true and another when that same condition evaluates to false you can use else.

int age = 30; // 🙎‍♀️
if (age < 25) {
    System.out.println("You cannot rent a car!");
}
else {
    System.out.println("You might be able to rent a car.");
}

You write the word else immediately after the } at the end of an if statement, then some code inside of a new { and }.

if (CONDITION) {
    <CODE TO RUN>
}
else {
    <CODE TO RUN>
}

When the condition evaluates to false, the code inside of else's { and } will run.

else cannot exist without a matching if, so this code does not work.

else {
    System.out.println("No if.");
}
