good day,i am new to programming,i got some errors.

import java.io.*;

import java.util.Vector;

class mark{

privateint mark=0;

public mark(int newMark){

this.mark=newMark;

}

publicint getMark(){

return mark;

}

}

publicclass test{

publicstaticvoid main(String[]args){

Vector mar =new Vector();

mar.addElement(new mark(3));

mar.addElement(new mark(1));

mar.addElement(new mark(2));

mar.addElement(new mark(4));

//below i get error

/*want to get 1st element in the vector*/

//mark temp=mar.elementAt(0);

/* want to print value of 1st mark*/

//System.out.println(mar.elementAt(0).getMark());
