Here you go. I added a constructor and a toString overload to make the object creation and printing as easy as possible.
public class student {
private String _id;
private String _name;
private String _address;
public student(String id, String name, String address) {
_id = id;
_name = name;
_address = address;
}
public String toString() {
return "Id: " + _id + "\nName: " + _name + "\nAddress: "+ _address;
}
public static void main(String[] args) {
student s1 = new student("S12345", "John Doe", "Some street");
System.out.println(s1);
}
}

Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
<u>ERD is designed using conceptual data model, logical data model, and physical data model</u>.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
