Dear mukesh,

I think the basic SOQL is like the following: 
List<Class__c> classes = [SELECT Id, (SELECT Id FROM Students__r) FROM Class__c];

If you want to retrieve a specific Class__c, add WHERE clause.

Hi Mukesh,

What exactly you want ,Do you want to display in detail page ? if yes you can edit your class layout then add student as a related list .

If you want in apex .then you can get in two diffrent way .

Parent to child and child to parent Query .

If you want only class Name in staudent query then go for child to parent which can be solved by dot notation like below .

Check below  link it will help !!
