Hello,
Can you please error check my javascript? It should do the following:
Write a program that uses a class for storing student data. Build the class using the given information.
The data should include the students ID number; grades on exams 1, 2, and 3; and average grade.
Use appropriate assessor and mutator methods for the grades (new grades should be passed as parameters).
Use a mutator method for changing the student ID.
Use another method to calculate the average grade.
Write a static method that will accept the two students as parameters and report which one has the highest average grade.
Test all constructors and methods using a separate driver class.
Here is my code so far:
public class Student
{
private int stuID;
private int grade1;
private int grade2;
private int grade3;
private int gradeAvg;
Student()
{
stuID=1;
grade1=90;
grade2=100;
grade3=98;
}
Student(int sID,int sgrade1,int sgrade2,int sgrade3)
{
stuID=sID;
grade1=sgrade1;
grade2=sgrade2;
grade3=sgrade3;
}
public int getStuID()
{
return stuID;
}
public void setStuID(int stuID)
{
this.stuID = stuID;
}
public int getGrade1()
{
return grade1;
}
public void setGrade1(int grade1)
{
this.grade1 = grade1;
}
public int getGrade2()
{
return grade2;
}
public void setGrade2(int grade2)
{
this.grade2 = grade2;
}
public int getGrade3()
{
return grade3;
}
public void setGrade3(int grade3)
{
this.grade3 = grade3;
}
int calculateAvgGrade()
{
gradeAvg=((grade1+grade2+grade3)/3);
return gradeAvg;
}
public static int HighGrade(Student s1, Student s2)
{
return(Math.max(s1.gradeAvg,s2.gradeAvg));
}
public static int HighGradeStudent(Student s1, Student s2)
{
if(s1.gradeAvg>s2.gradeAvg)
{
return(s1.stuID);
}
else
{
return(s2.stuID);
}
}
}
class StudentDemo
{
public static void main(String args[])
{
Student s1 = new Student();
System.out.println("Data of Student 1");
System.out.println("Student ID is: "+s1.getStuID());
System.out.println("Student grade1 is: "+s1.getGrade1());
System.out.println("Student grade2 is: "+s1.getGrade2());
System.out.println("Student grade3 is: "+s1.getGrade3());
System.out.println("Student1 Average grade is: "+s1.calculateAvgGrade());
Student s2 = new Student(2,80,90,100);
System.out.println(" Data of Student 2");
System.out.println("Student ID is: "+s2.getStuID());
System.out.println("Student grade1 is: "+s2.getGrade1());
System.out.println("Student grade2 is: "+s2.getGrade2());
System.out.println("Student grade3 is: "+s2.getGrade3());
System.out.println("Student2 Average grade is: "+s2.calculateAvgGrade());
Student s3 = new Student();
System.out.println(" Highest average grade is: "+s3.HighGrade(s1,s2));
System.out.println("Student ID who has got Highest grade:"+s3.HighGradeStudent(s1,s2));
}
}
Error: Main method not found in class Student, please define the main method as: public static void main(String[] args) or a JavaFX application class must extend javafx.application.Application Command exited with non-zero status 1
