How to Add Array In Another Array's Element Using Groovy?

To add an array as an element in another array using Groovy, you can simply use the add method. Here's an example:

1
2
3

def mainArray = []
def subArray = [1, 2, 3]
mainArray.add(subArray)

In this code snippet, mainArray is an empty array, and subArray contains elements [1, 2, 3]. By calling the add method on mainArray and passing subArray as an argument, subArray is added as an element to mainArray.

What is the operator for array concatenation in Groovy?

The operator for array concatenation in Groovy is the + operator.

How to combine two arrays in Groovy?

To combine two arrays in Groovy, you can use the + operator to concatenate the arrays. Here is an example:

1
2
3
4
5
6

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]

def combinedArray = array1 + array2

println combinedArray // Output: [1, 2, 3, 4, 5, 6]

Alternatively, you can also use the addAll() method to combine two arrays:

1
2
3
4
5
6

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]

array1.addAll(array2)

println array1 // Output: [1, 2, 3, 4, 5, 6]

How do you join multiple arrays in Groovy?

In Groovy, you can join multiple arrays using the plus operator. Here's an example:

1
2
3
4
5
6
7

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]
def array3 = [7, 8, 9]

def mergedArray = array1 + array2 + array3

println mergedArray

This will output:

1

[1, 2, 3, 4, 5, 6, 7, 8, 9]

You can use the plus operator to concatenate arrays together in Groovy.

How do you add two arrays in Groovy?

In Groovy, you can add two arrays by using the plus() method or the + operator. Here are some examples:

1. Using the plus() method:

1
2
3
4
5
6
7

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]

def combinedArray = array1.plus(array2)

println combinedArray
// Output: [1, 2, 3, 4, 5, 6]

1. Using the + operator:

1
2
3
4
5
6
7

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]

def combinedArray = array1 + array2

println combinedArray
// Output: [1, 2, 3, 4, 5, 6]

Both methods will concatenate the two arrays into a new array.

How do you concatenate multiple arrays in Groovy?

In Groovy, you can concatenate multiple arrays using the plus operator (+). Here is an example code snippet to concatenate two arrays:

1
2
3
4
5
6
7

def array1 = [1, 2, 3]
def array2 = [4, 5, 6]

def concatenatedArray = array1 + array2

println concatenatedArray
// Output: [1, 2, 3, 4, 5, 6]

You can concatenate as many arrays as needed by chaining the plus operator.
