Logical Operators Part 1

Now that you can compare values, let's learn how to combine multiple conditions. Logical operators allow you to build more complex expressions by connecting Boolean values together.

The AND operator (&&) returns true only when both conditions are true. If either condition is false, the entire expression is false:

fun main() {
    val age = 25
    val hasLicense = true
    
    val canDrive = age >= 18 && hasLicense
    println(canDrive)  // Prints: true
}

Both conditions must be met: the person must be at least 18 and have a license. If the age were 16, canDrive would be false even though hasLicense is true.

The OR operator (||) returns true when at least one condition is true. It only returns false when both conditions are false:

fun main() {
    val isWeekend = false
    val isHoliday = true
    
    val canSleepIn = isWeekend || isHoliday
    println(canSleepIn)  // Prints: true
}

Here, you can sleep in if it's a weekend or a holiday: only one needs to be true.
