java - How to extract numbers from a String into an array

I need to put all numeric values stored in a String into an array:

String str = "12,1,222,55";

If I do this, then it will merge all numbers:

str = str.replaceAll("\D+","");

How to get something like this?:

int[] result = new int[]{12,1,122,55};

First split the string. Then parse each element in String array to new array

String[] s=str.split("\D+");
int[] intarray=new int[s.length];
for(int i=0;i<s.length;i++){
   intarray[i]=Integer.parseInt(s[i]);
}
