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

2 minutes read

To add an array as an element in another array using Groovy, you can simply use the addAll() method or the + operator.


For example, if you have two arrays arr1 and arr2, and you want to add arr2 as an element in arr1, you can do so by using either of the following methods:

  1. Using the addAll() method: def arr1 = [1, 2, 3] def arr2 = [4, 5, 6] arr1.addAll(arr2) println arr1 // Output: [1, 2, 3, 4, 5, 6]
  2. Using the + operator: def arr1 = [1, 2, 3] def arr2 = [4, 5, 6] arr1 += arr2 println arr1 // Output: [1, 2, 3, 4, 5, 6]


Both methods will concatenate the elements of arr2 to the end of arr1, effectively adding arr2 as an element in arr1.


What are the steps to concatenate arrays in Groovy?

To concatenate arrays in Groovy, you can follow these steps:

  1. Create two arrays that you want to concatenate.
  2. Use the "+" operator to concatenate the arrays.
  3. Store the result in a new variable or overwrite one of the existing arrays with the concatenated result.


Here's an example:

1
2
3
4
5
6

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

def concatenatedArray = array1 + array2

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


Alternatively, you can also use the addAll() method to concatenate 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 to combine arrays in Groovy?

In Groovy, you can combine arrays by using the "+" operator or the "addAll()" method.


Using the "+" operator:

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]


Using the "addAll()" method:

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]


Both methods will result in a new array containing elements from both input arrays.


What is the Groovy command for combining the content of two arrays?

The + operator can be used to combine the content of two arrays in Groovy. Here's an example:

1
2
3
4
5
6

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

def combinedArray = array1 + array2

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