Using class Result (shown below) and making the minor modification that will ensure that objects of this class are serialisable, make method getResults available via an RMI interface. This method should return a Vector containing initialised Result objects that are set up by a server program (also to be written by you) and made available via an implementation object placed in the RMI registry by the server. The server should store two Result objects in the Vector contained within the implementation object. Access this implementation object via a client program and use the methods of the Result class to display the surname and examination mark for each of the two Result objects. (I.e., employ 'Method 1' from Section 5.4.)You should find the solution to the above problem relatively straightforward by simply modifying the code for the Bank example application from this chapter.
class Result implements java.io.Serializable
{
private String surname;
private int mark;
public Result(String name, int score)
{
surname = name;
mark = score;
}
public String getName()
{
return surname;
}
public void setName(String name)
{
surname = name;
}
public int getMark()
{
return mark;
}
public void setMark(int score)
{
if ((score>=0) && (score<=100))
mark = score;
}
}
