In the code below, I've added two lines that print output. The first line prints junk as usual, but surprisingly the second one gives me a compilation error. Why?

class Student {

  private String name;

  public Student(String name){
         this.name = name;
  }
  public String getName(){
         return name;
  }
}

class StudentServer {

   public StudentServer(){

          Student[] s = new Student[30];
          s[0] = new Student("Nick");

          // LINE 01: This compiles, although prints junk
          System.out.println(s[0]); 

          // LINE 02: I get a error called cannot find symbol
          System.out.println(s[0].getName());
   }

  public static void main(){
         new StudentServer();
  }
}

Many Thanks
