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);
}
}
