Share your code.
Take a look at my code. 
public class ContactSearch {
    
    public static list<contact> searchForContacts(string first, string postal){
        list<contact> c = new list<contact>([select id, name from contact where lastname =: first and mailingpostalCode=:postal]);
        return c;
    }

}

let me know if you have any further questions


Thanks
Pramodh
