What's the Kotlin equivalent of Java's String[]?

Question

I see that Kotlin has ByteArray, ShortArray, IntArray, CharArray, DoubleArray, FloatArray, which are equivalent to byte[], short[], int[],char[], double[]

Answer 1

Some of the common ways to create a String array are

1. var arr = Array(5){""}

This will create an array of 5 strings with initial values to be empty string.

2. var arr = arrayOfNulls(5)

This will create an array of size 5 with initial values to be null. You can use String data to modify the array.

3. var arr = arrayOf("zero", "one", "two", "three")

When you know the contents of array already then you can initialise the array directly.

4. There is an easy way for creating an multi dimensional array of strings as well.

   var matrix = Array(5){Array(6) {""}}

   This is how you can create a matrix with 5 rows and 6 columns with initial values of empty string.
