输入三个字符串，并看里边是否含有“Kobe”。
import java.util.Scanner;
import java.util.HashSet;
import java.util.Iterator;
public class Main{
@SuppressWarnings("unchecked")
public static void main(String[] args){
//write your own codes
HashSet<String> set = new HashSet();
Scanner scan = new Scanner(System.in);
for(int i=0;i<3;i++){
String s = scan.next();
set.add(s);
}
Iterator<String> it = set.iterator();
boolean flag = false;
String str = "Kobe";
while(it.hasNext()){
String st = it.next();
if(st.equals(str)){
flag = true;
break;
}
}
System.out.println(flag);
}
}
