Hello, can you please help me with this Java homework? Here are the indications and I also attached two pictures with the notes (slides13-17 are in those two pictures) 

  • Create a Java program for the definition for the class Student
    • Slides 13 - 16 are for class definition
  • Create a Java application program to use this class
    • Slide 17 is for the application
    • Name your application program as useStudent_YourInitial.java
  • Submit the both programs (the class definition & the application) and the screenshot of your compiler window.
The Student Class /** Gets the number of units earned. * @return The number of units this student has earned */ public int getUnits () { return unitsEarned; /** * Sets whether the student is paid up. /** } * @param flag The value true or false indicating paid-up status */ } public void setPaidUp (boolean flag) { paidUp = flag; } *Returns whether the student is paid up. * @return Whether the student is paid up */ public boolean isPaidUp () { return paidUp; } The Student Class /** * Creates a string identifying this student. * @return The string used to display this student Names for getter methods usually begin with the prefix get. The only exception is for getter methods that return a boolean, in which case the name typically begins with is. public String toString() { return studentName + 17 (#" + studentID + ")"; } /* Public constants */ /** The number of units required for graduation */ public static final int UNITS_TO_GRADUATE = 180; /* Private instance variables */ private String studentName; /* The student's name private int studentID; private int unitsEarned; private boolean paidUp; The toString method tells Java how to display a value of this class. All of your classes should override toString. Classes often export named constants. /* The student's ID number /* The number of units earned /* Whether student is paid up These declarations define the instance variables that maintain the internal state of the class. All instance variables used in the text are private. */ */ */

Using the Student Class ▸ Once you have defined the Student class, you can then use its constructor to create instances of that class. For example, you could use the following code to create two Student objects: ► You can then use the standard receiver syntax to call methods on these objects. For example, you could set Hermione's number-of-units field to 263 by writing topStudent.setUnits (263); or get Harry's full name by calling Student topStudent = new Student ("Hermione Granger", 314159); Student chosenOne = new Student ("Harry Potter", 123456); chosenOne.getName(); ►We use a class in another class, which is a driver class defined in an application The Student Class /** * Gets the name of this student. * @return The name of this student public String getName() { return studentName; } /** * Gets the ID number of this student. * @return The ID number of this student */ public int getID () { return studentID; } /** * Sets the number of units earned. * @param units The new number of units earned public void setUnits (int units) { unitsEarned = units; } These methods retrieve the value of an instance variable and are called getters. Because the student name and ID number fixed, there are Normal nding setters. AVA This method changes the value of an instance variable and is called a setter.
