Alright I don't know what is going wrong here.  When I complie the
class it works fine but when I try and compile a class that makes an
instance of the class I get the following error message

ShowStudent.java:9: 'void' type not allowed here
        System.out.println("Studend ID - " + newstudent.getid());
                           ^
ShowStudent.java:10: 'void' type not allowed here
        System.out.println("Credit Hours Earned - " +
newstudent.getch());
                           ^
ShowStudent.java:11: 'void' type not allowed here
        System.out.println("Points Earned - " + newstudent.getpe());
                           ^
ShowStudent.java:12: 'void' type not allowed here
        System.out.println("GPA - " + newstudent.getgpa());

Here is the class and instance.

   public class Student
  {
     private int id;
     private int ch;
     private int pe;
     private double gpa;
      public static void main(String[] args)
     {

     }
      public void setid(int a)
     {
        id = a;
     }
      public void setch(int a)
     {
        ch = a;
     }
      public void setpe(int a)
     {
        pe = a;
     }
      public void getid()
     {
        System.out.print(id);
     }
      public void getch()
     {
        System.out.print(ch);
     }
      public void getpe()
     {
        System.out.print(pe);
     }
      public void getgpa()
     {
        gpa = pe / ch;
        System.out.print(gpa);
     }
  }

   public class ShowStudent
  {
      public static void main(String[] args)
     {
        Student newstudent = new Student();
        newstudent.setid(1234);
        newstudent.setch(12);
        newstudent.setpe(48);
        System.out.println("Studend ID - " + newstudent.getid());
        System.out.println("Credit Hours Earned - " +
newstudent.getch());
        System.out.println("Points Earned - " + newstudent.getpe());
        System.out.println("GPA - " + newstudent.getgpa());
     }
  }
