hi can tell what's the error , am unable to understand error. any suggestion
The List which you're using are not of concret SObject, You will have the follwing changes:
Add the __c to the custom Object name
List<StudentClass__c> students =new List<StudentClass__c>();
Please follow the same to the other Lists as well
Hope this helps!!

I think
if(Stds.sNo==stNo)
should be
if(student.sNo==stNo)
The List which you're using are not of concret SObject, You will have the follwing changes:

public static StudentClass searchStudent(Integer stNo, List<StudentClass> stds) { for (College.StudentClass student : stds) { if (student.sNo == stNo) { return student; } } return null; // Added this line to handle the case when student is not found. }By making this change, the error should be resolved, and the searchStudent method should function correctly.
