Java提取两个字符串中的相同元素方法

如下所示：

public static void main(String[] args) {

String str1 = "刘烨,孙坚,王二小,蜘蛛侠,钢铁侠,毛剑卿";
String str2 = "王二小,李占军,刘胡兰,毛剑卿";

String[] arr1 = str1.split(",") ;
String[] arr2 = str2.split(",") ;
StringBuffer sb = new StringBuffer();
for (int i = 0; i < arr2.length; i++){
for (int j = 0; j < arr1.length; j++){
 if (arr1[j].equals(arr2[i])){
  sb.append(arr1[j] + ",") ;
  }
 }
}
  System.out.println("结果：" + sb.toString().substring(0, sb.toString().length() - 1));

}

输出： "结果：王二小,毛剑卿"
