In Java I need to create a 2 new Student objects in a main method. The first will have name, major, 16 hours completed, and a 3.8 gpa. The 2nd will have name and major. they just started scool and have no hours completed or gpa. I need to change the 2nd students major. I need to update the students information based on hours they took and return a class level. public class Student { private String name; private String major; private double gpa; private int hoursCompleted; /**Constructor * @param name * The student's name * @param major * The student's major */ public Student(String name, String major) { this.name = name; this.major = major; this.gpa = 0.0; hoursCompleted = 0; } /**Constructor * @param name * The student's name * @param major * The student's major * @param gpa * The student's cumulative gpa * @param hoursCompleted * Number of credit hours the student has completed */ public Student(String name, String major, double gpa, int hoursCompleted) { this.name = name; this.major = major; this.gpa = gpa; this.hoursCompleted = hoursCompleted; } /** * @return The student's major. */ public String getMajor() { return major; } /** * @param major The major to set. */ public void setMajor(String major) { this.major = major; } /** * @return The student's name. */ public String getName() { return name; } /** * @param name The name to set. */ public void setName(String name) { this.name = name; } /** * @return The student's gpa. */ public double getGpa() { return gpa; } /** * @return The number of credit hours the student has completed. */ public int getHoursCompleted() { return hoursCompleted; } /** * @return The student's class (Freshman, Sophomore, Junior, Senior) */ public String getClassLevel() { String classLevel; if (hoursCompleted < 30) { classLevel = "Freshman"; } else if (hoursCompleted < 60) { classLevel = "Sophomore"; } else if (hoursCompleted < 90) { classLevel = "Junior"; } else { classLevel = "Senior"; } return classLevel; } /**Update student's information to reflect completion of a semester's work * @param semHours * Number of credit hours the student has just completed * @param semGPA * GPA for the semester just completed */ public void updateStudent(int semHours, double semGPA) { int oldHours = hoursCompleted; hoursCompleted = oldHours + semHours; gpa = (oldHours *gpa + semHours * semGPA) / hoursCompleted; } /** Print the student's name and class */ public void printClassLevel() { System.out.println(name + " is a " + getClassLevel()); } /**Prints the information about a student in a nice format with * appropriate labeling */ public void print() { DecimalFormat fmt = new DecimalFormat("0.000"); System.out.println(name + " is a " + getClassLevel() + " " + major); System.out.print("who has completed " + hoursCompleted + " hours "); System.out.println("with a " + fmt.format(gpa) + " gpa."); } }
