To get the first and last element of an array in Groovy, you can use the first() and last() methods respectively. Here are some examples:
// Example 1: Using first() and last() methods on an integer array
def numbers = [10, 20, 30, 40, 50]
def firstElement = numbers.first()
def lastElement = numbers.last()
println("First Element: ${firstElement}") // Output: First Element: 10
println("Last Element: ${lastElement}") // Output: Last Element: 50
// Example 2: Using first() and last() methods on a string array
def names = ["John", "Mary", "Samantha", "David"]
def firstPerson = names.first()
def lastPerson = names.last()
println("First Person: ${firstPerson}") // Output: First Person: John
println("Last Person: ${lastPerson}") // Output: Last Person: David
In both examples, we first initialize an array and then use the first() and last() methods to get the first and last elements. We store these values in separate variables and then print them using println().
