字串中找最長數字串

package com.huang.algorithms;public class Test {/** * @param args */public static char[] c;public static boolean isNum(char c){int i = (int)c;//ascii '1' 49 '9' 57if(i >= 49 && i <= 57){return true;}else{return false;}}public static int getMaxSeqNum(){int max = 0;int now = 0;for(int i = 0; i < c.length; i++){if(isNum(c[i])){now++;}else{now = 0;}if(now > max){max = now;}}return max;}public static void main(String[] args) {// TODO Auto-generated method stubc = "1b123c1234dfert1234567b2".toCharArray();System.out.print(getMaxSeqNum());}}
