Questiоn 1 - Student Clаss [45 mаrks] 1.1. Creаte the Student class with the fоllоwing properties which will not be accessible from outside the class: the student's name, the student's mark the student's date of birth stored in a string (format: "yyyy-MM-dd") (6) 1.2 Create a static constant called: HAPPY and set it equal to: "(✿◠‿◠)" (or any smiley face, EG 🙂 ). and another called SAD and set it equal to: "( ˘︹˘ )" (or any sad face). These constants can be accessed from outside the class. (4) 1.3. Create a static variable called totalMarks which will store the total of all the students' marks. Create another static variable called numStudents which will keep track of the number of Student objects which have been instantiated. These two variables must not be accessible from outside the class. (2) 1.4. Create a parametrised constructor method to give values to the three instance variables. Ensure that totalMarks is updated by adding the mark to its current value. Also update numStudents when a new object is instantiated. (5) 1.5. Create accessor and mutator methods for the student's name and mark. (4) 1.6. Create a getAge() method which will return the student's age as an integer. The age must be calculated accurately using the correct date and time classes. (6) 1.7. Create a getAverageMark() method which will return the average mark of all Student objects. The mark must be rounded off to two decimal places. (5) 1.8. Create a toString() method which will return a String giving the following message: Hello You got % Where name and mark are the values from the instance variables. (4) 1.9. Code a method called message() which will return a String. The String must contain either HAPPY faces or SAD faces. If the student's mark is 50 or above, then the message contains some HAPPY faces, otherwise, it contains some SAD faces. The number of faces must be: mark/10 (integer division). EG a mark of 56% will give the message: (✿◠‿◠) (✿◠‿◠) (✿◠‿◠) (✿◠‿◠) (✿◠‿◠) A mark of 33% will give the message:( ˘︹˘ ) ( ˘︹˘ ) ( ˘︹˘ ) (9) Copy and Paste your code from NetBeans into the space below:
