循环遍历两个字符串以逗号分隔

第一种，单个字符串和多个逗号分隔的

第一步：定义2个字符串

String receiver = "zhangsan,lisi,wangwu";
String receiver1 = "zhangsan";

第二步：定义逗号分隔数组

String[] str = receiver.split(",");

第三步：循环比对

       for (int i = 0; i < str.length; i++) {
            if (str[i].equals(receiver1)){
                System.out.println(receiver1);
            }
        }

第二种，多个逗号分隔字符串对比

第一步：定义2个字符串

      String receiver = "zhangsan,lisi,wangwu";
      String receiver1 = "zhangsan,lisi";

第二步：定义逗号分隔数组

 String[] str = receiver.split(",");
 String[] str1 = receiver.split(",");

       for (int i = 0; i < str1.length; i++) {
            String[] str2 = receiver1.split(",");
            for (int j = 0; j <str2.length ; j++) {
                if (str1[i].equals(str2[j])){
                    System.out.println(str1[i]+"----------"+str2[j]);
                }
            }
        }
