In Scala, and and or are represented by the keywords && and ||, respectively. The && operator returns true if both the conditions are true, otherwise it returns false. The || operator returns true if at least one of the conditions is true, otherwise it returns false.
Here is an example of using &&:
val x = 5
val y = 10
if (x > 0 && y > 0) {
println("Both x and y are positive")
}
In this example, the && operator is used to check if both x and y are positive. If both are positive, then the message "Both x and y are positive" will be printed.
Here is an example of using ||:
val x = 5
val y = -5
if (x > 0 || y > 0) {
println("At least one of x and y is positive")
}
In this example, the || operator is used to check if either x or y is positive. Since x is positive, the message "At least one of x and y is positive" will be printed.
