In Groovy, you can get the maximum or minimum of two numbers by using the Math.max or Math.min functions respectively. Here are examples:
def a = 5
def b = 10
// get the maximum of a and b
def maxNumber = Math.max(a, b)
println("The maximum of $a and $b is $maxNumber")
// get the minimum of a and b
def minNumber = Math.min(a, b)
println("The minimum of $a and $b is $minNumber")
Output:
The maximum of 5 and 10 is 10
The minimum of 5 and 10 is 5
