Constructors help us to guarantee every object has the required attributes.$$ Getters and setters help us to control what attributes can be read and which ones can be updated.$$ In this example, we want apps to READ the Section's sectionId and course, but we don't want apps to be able to update those values.$$ Which class implementation best accomplishes this?$$ Assume that each code block below contains the correct attributes and constructor.$$

Group of answer choices

public class Section $\{$

$//$ private sectionId and course attributes, public constructor

$$public String getSectionId$()\{$

$$return sectionId;

$\}$

$$public Course getCourse$()\{$

$$return course;

$\}$

$//$ private sectionId and course attributes, public constructor

$$public void setSectionId$($String $\_$sectionId$)\{$

$$section $=\_$section;

$\}$

$$public void setCourse$($Course $\_$course$)\{$

$$course $=\_$course;
