将整数的每一位分离出来

public class SplitNumber{public static void main(String[] args){int length = args[0].length();System.out.println("整数长度为："+length);int[] nums = new int[length];int tem = 10;//用所给整数除以tem以获取最高位数值，对tem取余获取低n-1位整数for (int i=0; i<length-2; ++i)tem *=10;int a = Integer.parseInt(args[0]);for (int i=0; i<length; ++i){nums[i] = a/tem;a %= tem;tem /= 10;}//输出整数的各位数值for (int i=0; i<length; ++i){System.out.print(nums[i]+" ");}}}
