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]);
            }
        }
    }
