java - char array to int array -

i'm trying convert string array of integers perform math operations on them. i'm having trouble following bit of code:

string raw = "1233983543587325318";  char[] list = new char[raw.length()]; list = raw.tochararray(); int[] num = new int[raw.length()];  (int = 0; < raw.length(); i++){     num[i] = (int[])list[i]; }  system.out.println(num); 

this giving me "inconvertible types" error, required: int[] found: char have tried other ways character.getnumericvalue , assigning directly, without modification. in situations, outputs same garbage "[i@41ed8741", no matter method of conversion use or (!) value of string is. have unicode conversion?

there number of issues solution. first loop condition i > raw.length() wrong - loops never executed - thecondition should i < raw.length()

the second cast. you're attempting cast integer array. in fact since result char don't have cast int - conversion done automatically. converted number isn't think is. it's not integer value expect in fact ascii value of char. need subtract ascii value of 0 integer value you're expecting.

the third how you're trying print resultant integer array. need loop through each element of array , print out.

    string raw = "1233983543587325318";      int[] num = new int[raw.length()];      (int = 0; < raw.length(); i++){         num[i] = raw.charat(i) - '0';     }      (int : num) {         system.out.println(i);     }
