Java Convert String to Array “[1,2,3,4,5,5]” to [1,2,3,4,5,5]

I am trying to convert a string which is a in the format

String x= "["a","1"]" ;


String [] vals =["a" , "1"];

I am currently doing it in two steps

  1. removing the [ & ] from the string
  2. Splitting the string with at the comma character

String x2=""a","1""



I exactly, don’t gather whether you want an array of Strings or an array of Integer as your result, but for the example, you have provided, this should work.

import java.util.Arrays;
class HelloWorld {
    public static void main(String[] args) {
        String x = "["a","1"]";
        String[] array = x.split(""");
        array = -> i.matches("[\dA-Za-z]")).toArray(String[]::new);

I have filtered the array because initially there will be some empty strings and opening and closing braces as strings.
