To add the lookup field .. first you need to inseet the refernce 
and the insert the child like below 
  
account acc = new account(Name ='Test');
 insert acc;
       
      Contact e = new Contact();
e.LastName='Test'
        e.AccountId = acc.id;
        insert e;

Or you can query and assign it also ..like below 

  
account acc  =[Select Id from Account Limit 1 ];
       
      Contact e = new Contact();
e.LastName='Test'
        e.AccountId = acc.id;
        insert e;

Hello Patel Sujeet,

When I try to create the contact1__c It gives me this error :  Invalid type: contact1__c  because it's not an object it is just a lookup field on Contact
