Reverse (parse the output) of Arrays.toString(int[])

Question

Is there in the JDK or Jakarta Commons (or anywhere else) a method that can parse the output of Arrays.toString, at least for integer arrays?

int[] i = fromString(Arrays.toString(new int[] { 1, 2, 3} );

Answer 1

Pretty easy to just do it yourself:

public class Test {

public static void main(String args[]){
 int[] i = fromString(Arrays.toString(new int[] { 1, 2, 3} ));
}

private static int[] fromString(String string) {
 String[] strings = string.replace("[", "").replace("]", "").split(", ");
 int result[] = new int[strings.length];
 for (int i = 0; i < result.length; i++) {
  result[i] = Integer.parseInt(strings[i]);
 }
 return result;
}

}
