Return array in Groovy

To return an array in Groovy, you can create the array using square brackets notation and then use the return keyword to return the array from a method.

Here is an example method that returns an array of integers:

def getIntegerArray() {
    def integers = [1, 2, 3, 4, 5]
    return integers
}
// calling the method and printing the array

println getIntegerArray()

Output:

[1, 2, 3, 4, 5]

You can also use the def keyword to define the array and then return it in one line:

def getStringArray() {
    def strings = ["Groovy", "is", "cool"]
    strings
}
// calling the method and printing the array

println getStringArray()

Output:

[Groovy, is, cool]

Note that in this example, we did not need to use the return keyword. The last line of the method is an implicit return, which returns the strings variable.
