How to split string into substring in kotlin??

Answer 1

Ritesh Singh
var a:String=readLine()!!.toString()
var arr=a.split(",")
print(arr[1])

Answer 2

Use substring() method

var a:String="hello"
print(a.substring(1,3))
//output: el

Answer 3

It can be simplified down to:
val arr = readLine()!!.split(",")

arr will automatically get typed to Array<String> with arr.size elements. You can make it val as the Array class won't be changing even if you overwrite the contained elements.

Answer 4

I just want to split a string by "," by given symbol to array of string.
