structure Boolean in Groovy

Boolean data type in Groovy represents a logical value. It can have two possible values: true or false. Booleans are commonly used in conditional statements, loops and comparisons.

Here are some examples of using Boolean in Groovy:

1. Declaring and initializing a Boolean variable:

def isSunny = true

2. Using Boolean in a conditional statement:

if (isSunny) {
  println("It's a sunny day!")
} else {
  println("It's a cloudy day.")
}

3. Comparing two Boolean values:

def isRaining = false
if (isSunny && !isRaining) {

  println("It's a beautiful day!")

}

4. Using Boolean as a return value:

def isPrime(int num) {
  if (num == 2 || num == 3) {
    return true
  } else if (num <= 1 || num % 2 == 0) {
    return false
  }
  
  def i = 3
  while (i * i <= num) {
    if (num % i == 0) {
      return false
    }
    i += 2
  }
  return true
}

5. Boolean operations:

def a = true
def b = false
//Negation

assert !b
//Logical OR

assert a || b
//Logical AND

assert a && b == false

These are just a few examples to demonstrate how Boolean can be used in Groovy code.
