Error on Trailhead 'ContactSearch' Apex class

Hello,

I alway get error "Challenge not yet complete... here's what's wrong: 
Executing the 'searchForContacts' method failed. Either the method does not exist, is not static, or does not return the expected contacts."

I have my code as following:
public class ContactSearch {
    public List<Contact> searchForContacts (String cName, String pCode) {
        
        List<Contact> matchCon = [SELECT Id, First_Name__c, Last_Name__c, MailingPostalCode__c FROM Contact
                                  WHERE Last_Name__c = 'cName'
                                  AND MailingPostalCode__c = 'pCode']; 
        
        if(matchCon.size() > 0){
            return matchCon;
        } else {
            return null;
        }
    }
}

Kindy check and tell me what is wrong

thank in advance

@Visal:

"Executing the 'searchForContacts' method failed. Either the method does not exist, is not static, or does not return the expected contacts." has your answer, the method you defined is not static.

Make it:
 public Static List<Contact> searchForContacts (String cName, String pCode) 

and also in the query, instead of using variable names, you had given them in quotes which make them string., change query to 

  List<Contact> matchCon = [SELECT Id, First_Name__c, Last_Name__c, MailingPostalCode__c FROM Contact
                                  WHERE Last_Name__c = :cName
                                  AND MailingPostalCode__c = :pCode]; 

Hope it helps.,

Thanks,

Hello Balaji,

thank you for your reply.
The method should return a list of Contact records with at least the ID and Name fields. This is the requirement, so the method must not be static.
Kindly refer to below link to original problem.

Hello Visal, I think you confused static for void, Coming to the challenge, " The Apex class must have a public static method called 'searchForContacts'." This is the second point in the challenge, take a moment to read it! Thanks, Balaji

thanks in advance

Same with @Himanshu Nimje,
In the challange it only says "find same last name and same postal code", so why not useing
Name like '%targetLastName' and MailingAddress like 'targetPostalCode%'

but useing
[SELECT Id, First_Name__c, Last_Name__c, MailingPostalCode__c FROM Contact
                                  WHERE Last_Name__c = :cName
                                  AND MailingPostalCode__c = :pCode];

So we have to create new custome field inorder to pass this challenge?

Dear Hunter's 
I passed that challenge with below code:
**********************************************************************************
public class ContactSearch {

    Public static List<Contact> searchForContacts(String lName, String mCode){
        List<Contact> qContact = [select id, firstName, lastName, phone from contact
                                         where lastName =: lName AND MailingPostalCode =: mCode ];
return qContact;      
    }
}

Try this code. It worked for me

public class ContactSearch {
    public static List<Contact> searchForContacts(String m,String n){
        List<Contact> con= [Select Id,Name from Contact where (LastName =:m AND MailingPostalCode =:n)];
        return con;
    }
}
