我如何显示两个事件中参与者的价值

Question

Q值。创建名为Participant的类，其中包含名称，年龄和街道地址的字段。包括为每个字段分配参数值的构造函数和返回包含所有值的String的toString（）方法。

还包括一个equals（）方法，如果它们在所有三个字段中具有相同的值，则确定两个参与者是相等的。

创建一个包含两个阵列的应用程序，每个阵列至少包含5个参赛者 - 一个参加者参加迷你马拉松比赛，另一个参赛者参加跳水比赛。向用户提示两个事件中的参与者将文件保存为Participant.java和TwoEventParticipants.java。* /

到目前为止，这是我的代码。 如何显示两个活动中参加者的价值？

Answer 1

这适合您：

for(Participant p : mini){
   if(diving.contain(p)){ 
       System.out.pringtln(p.toString()) ; 
   }
}
