Hello! I am stuck on my java code and am unsure how to execute it. I've attached the UML Class diagram, instructions, and what the expected output should be. What is the java code for this lab? Thanks in advance!

Expected Output:

Test_AssignmentHierarchy code:

Assignment code from Lab 02:

public class Assignment { private String assignCourse = null; private String assignSctn = null; private String assignType = null; private int assignDue = 0;

public Assignment(){}

public Assignment(String course, String sctn, String type, int due) { this.assignCourse = course; this.assignSctn = sctn; this.assignType = type; this.assignDue = due; }

public final String getAssignCourse() { return assignCourse; }

public final void setAssignCourse(String assignCourse) { this.assignCourse = assignCourse; }

public final String getAssignSctn() { return assignSctn; }

public final void setAssignSctn(String assignSctn) { this.assignSctn = assignSctn; }

public final String getAssignType() { return assignType; }

public final void setAssignType(String assignType) { this.assignType = assignType; }

public final int getAssignDue() { return assignDue; }

public final void setAssignDue(int assignDue) { this.assignDue = assignDue; }

public String toString() { return "A(n) " + this.getAssignType() + " is due on " + this.getAssignDue() + " for " + this.getAssignCourse() + "." + this.getAssignSctn(); } }

The instance variable assignType has been removed. See sample output for modifications to toString method. 2. Mutator and accessor methods must be defined as "final" methods. There is no exception to this rule. 3. Mutator and accessor methods must always be named according to the Basic Coding Standards. This UML diagram follows those standards. 4.

Lab 04 SuperClasses and SubClasses General Information Beginning from your solution for Lab 02, create a Class hierarchy including Assignment (supeclass), Quiz(subclass), and Project(subclass) classes. Instructions Modify class Assignment to meet the revised requirements described in the UML Class Diagrams attached to the assignment. Create two new subclasses, Quiz and Project, based on the superclass Assignment, according to the UML Class Diagrams attached to the assignment. This lab will adhere to the published Basic Coding Standards. Failure to follow the standards will result in an assignment grade of zero (O). Zip the three (3).java source files (Assignment.java, Quiz.java, and Project.java) into a compressed folder named Lab04 Submission. Include source code for the object classes only in the zipped folder. DO NOT include the test harness (TestAssignmentHierarchy.java), edit/backup versions (with the in the file type) of the source code, or compiled code (.class files); submission of either will result in a grade of zero (O). Submit only the zipped folder Lab04 Submission as an attachment to this assignment. Provided to You The following resources are provided: These instructions, including sample toString output The UML Class Diagrams for the Assignment hierarchy Atest harness to use in testing your Assignment hierarchy, including classes Quiz and Project. Requirements The provided UML Class Diagrams explain the requirements for the changes to Assignment.java and creation of the subclasses. In addition to the requirements described there, be aware of the requirements included in the Basic Coding Standards. Specifically be aware of the following: All set and get methods must use standard naming (i.e. "set" or "get" followed by the instance variable name, adjusted for proper camel casing). All get and set methods must be 'final methods. The only direct access to instance variable values is through the set and get methods; no other direct access is every permitted. Expected Output Execution of the provided test harness should produce the results shown here. Slight alterations of spacing or working within the toString return are acceptable, but order of data items must match that shown. The highlighted portion of the subclass output originates in the superclass toString method. *** Some number will appear here *** Assignment.java passed minimal standards check. Quiz.java passed minimal standards check. Project.java passed minimal standards check.
