统计子串在另一个字符中出现的次数

package cc;//要求：统计一个子串在一个字符串中出现的次数//思路：不断地截取子串public class StringTest1 {public static void main(String[] args) {StringDemo1 demo1 = new StringDemo1();System.out.println("出现的次数是" + demo1.count("abcabcccabc", "abc"));}}class StringDemo1 {public int count(String string, String subString) {int count = 0;while (string.indexOf(subString) != -1) {// 只要子串在原串中出现count++;int local = string.indexOf(subString);string = string.substring(local + 1);// 注意是local+1}return count;}}
