$2.)$ Modify $1.)$ from above. Add a new Method called selectDB$()$ that takes only one argument, SID. When a user calls this method, it should SELECT from the database that Student and get all the Student$$s data from the database, and put this data into the appropriate properties. $($Hint: You will use an SQL Select statement here.$)$ Test out this method in the main.

Testing Code in Main$()$ method $$

Student s$1=$ new Student$()$;

s$1.$selectDB$(4)$; $//$accessing DB

s$1.$display$()$; $//$displays all data from DB for student with id$=4$

$3.)$ Modify $2.)$ from above. This time we are add another method called insertDB$().$ This method will take all $5$ data elements as arguments. This method will then Insert this information into the Student table, as well as fill up the object with the data provided. $($Hint: You will use an SQL Insert statement here.$)$

Testing Code in Main$()$ method $$

Student s$2=$new Student$()$;

s$2.$insertDB$(33,$Frank$,$Mayes$,$fmayes@yahoo.com$,3\mathrm{.}3)$;

s$2.$display$()$;

$4.)$ Lastly add $2$ functions to your Student class, updateDB$()$ and deleteDB$().$ These functions will update and delete student data in the database.
