反转（解析输出）Arrays.toString（int []）

自己动手很容易：

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;  }}
