    Default What is wrong with my code

    Hi guys i can't work out what is wrong with my code here
    public class Student
    {
        // instance variables - replace the example below with your own
        private String Id;
        private String stuName;
        private int gradeAverage;
     
         /**
         * Constructor for objects of class Student
         */
          public Student()
         {
             // initialise instance variables
             Id = "20054425";
             stuName = "Marco Perrozzi";
             gradeAverage = 80;
         }
     
     
         public Student(String Id, String stuName, int gradeAverage)
         {
            // initialise instance variables
            Id = Id;
            stuName = stuName;
            gradeAverage = gradeAverage;
         }
     
         public String getId()           { return Id;}
     
         public String getstuName()      {return stuName;}
     
         public int getgradeAverage()       {return gradeAverage;}
     
        }


    THAT NEEDS TO LINK UP WITH THIS

    public class StudentClient
    {
        public static void main(String args[]){
     
            Student defaultStudent = new Student("12345", "Marco P", 90);
     
            System.out.println("Default student Id is: "+defaultStudent.getId());
            System.out.println("Default Student Name is: "+defaultStudent.getstuName());
            System.out.println("Default Grade average is: "+defaultStudent.getgradeAverage());
     
            defaultStudent.SetId("3546737");
            defaultStudent.setstuName("John D");
            defaultStudent.setgradeAverage(35);
     
          //  System.out.println("Default student Id is: "+infoStudent());
            System.out.println("Info student Id is: "+ defaultStudent.getId());
            System.out.println("Info Student Name is: "+ defaultStudent.getstuName());
            System.out.println("Info Grade average is: "+ defaultStudent.getgradeAverage());
     
     
     
        }
    }

    So what am i doing wrong and what are the mistakes ?

    Thanks

    Where is that method defined?

    NOTE: java is case sensitive. There are two errors in what you posted:
    Cannot find symbol method setID (java.lang.string.);
    Both setId and string are spelled differently in the code.
    If you don't understand my answer, don't ignore it, ask a question.

    No. The variables and class names need to be spelled correctly. Look at the API doc for the correct spelling.

    Where is the setId method defined in the Student class?

    Hi,

    Where you defined getter(getId(),getstuName(),getgradeAverage()) and setter(setId(),setstuName(),setgradeAverage()) methods. Please post the full code here.

    Thanks

    You keep ignoring this question:

    Where is the setId method defined in the Student class?
