何が悪いんだろうか？

Superbadgeもうまくいかんし、Apexも何が悪いんだか...

分からん

もう今日は止めよう。8時間かかっても、３しかクリアーできなかった

List<Contact> updateContactList = new List<Contact>();
Set<String> ContactSet = new Set<String>();

ContactSet.add('Abigail Mason;[e-mail]');

Set<String> xxxSet = new Set<String>():
Map<String,String> xxxMap = new Map<String,String>();
for (String con : ContactSet){
    List<String> xxx = con.Split(';');
    xxxSet.add(xxx[0]);
    xxxMap.put(xxx[0],xxx[1]);    
}

List<Contact> ContactList = [select Id,Name from contact where Name =: xxxSet];
for (Contact con : ContactList){
    Contact c = new Contact();
    c.Id = con.Id ;
	String e = (String)xxxMap.get(c.Name);
    if (e != null) {
        c.email = e;
    	updateContactList.add(c);    
    }   
    
}
