          Object data2 = new Student("Ahmed", "Engineering", 456);
          Object data3 = new Student("john", "Computing", 789);     
          ChainNode c1 = new ChainNode(data1, null);
          ChainNode c2 = new ChainNode(data1, c1);
          ChainNode c3 = new ChainNode(data1, c2);
          ConsoleIO.out.println(" " + c3);
     }     //this is ChainNode
import textio.*;
import java.util.*;
public class ChainNode
     private Object element;
     private ChainNode next;
     public ChainNode(Object element, ChainNode next)
          this.element = element;
          this.next = next;
     public String toString()
          return new String("Node = " + element);
}//this is student
import textio.*;
import java.util.*;
public class Student implements java.lang.Comparable
     public Student(String aName, String aCourse, int matric)
          theName = aName;
          theCourse = aCourse;
          theMatric = matric;
    public final boolean    equals(Object obj) {  
        return this.compareTo(obj) == 0;
    public final int    compareTo(Object obj) {   
        int parMatric = ((Student)obj).getMatricNumber();
        int result = 0;
        if(theMatric < parMatric)
             result = -1;
        else if(theMatric == parMatric)
             result = 0;
        else
              result = 1;
        return result;
    }    // method: compareTo
     public int getMatricNumber()
          return theMatric;
    public int    hashCode() {   
        Integer theMatNum = new Integer(theMatric);
        return theMatNum.hashCode();
    }    // method: hashCode     
     String theName;
     String theCourse;
     int theMatric;     
}it gives me: "Student@7b"

Try adding a toString() method in Student - currently you are only getting the method defined by Object
