Sequential.java [28:1] cannot resolve symbol

Question

The program asks users to enter random numbers.They are stored in a vector. The numbers are then added and the results of the addition stored in an vector.ie
sum1=item1
sum2=item1+item2
sum3=item1+item2+item3
sumn=item1+item2+,,,,,+itemn
here is the program
import java.util.Vector;
import java.io.*;
public class Sequential {
/** Creates a new instance of Sequential */
public Sequential() {
public static int inputInt(String str){
BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
System.out.println(str);
int val;
try{
val = Integer.parseInt(input.readLine());
}catch(Exception e){}
return val;
public static void main (String args[]){
//initialising
Vector myarray = new Vector();
Vector sum = new Vector();
int ans = 0;
int dim;
dim = inputInt("Enter the array dimension");
//populate the
for(int i=0; i < dim; i++){
myarray.add(i,inputInt("Enter the array dimension"));
for(int i=0; i < dim; i++ ){
ans = Integer.parseInt(myarray.get(i)) + ans;
sum.add(i,ans);
for(int i=0; i < dim; i++){
System.out.println("Item [" + i + "] is " + sum.get(i));
it dispalys on ".add" part
Sequential.java [28:1] cannot resolve symbol in
myarray.add(i,inputInt("Enter the array dimension"));

Answer 1

Vectors store objects, not primitives.
Try the Integer wrapper class, e.g. myarray.add(i, new Integer(inputInt("Enter the array dimension")));
There are some other code problems I think you'll notice, but you should be able to work those out.
