Question

逗号分隔的字符串，如何利用到索引

Answer 1

package com.avvvit.test;
public class CompareToString {
public static void main(String[] args) {
//这个是得到字符串的第五个轿贺逗号的方法
String str = "aa,bb,cc,dd,ee,fdd,ccc";
String str2 = str;
int n =0;
for (int i = 0; i < 5; i++) {
//n = str.indexOf(",");
str=str.substring(str.indexOf("配镇,")+1);
//System.out.println("for:"+str);

}
//System.out.println("str:"+str+"....."+str2);
System.out.println("培帆粗indexoF:"+(str2.lastIndexOf(str)-1));

}
}
