Reading content of a file into an int array

Question

How do i use FileReader rd = new FileReader(filename) to read the contents into an int array?

Answer 1

public static int[] parse_file(String filename)
     Vector vec = new Vector();
     int num[];
     num = new num[vec.size()];
     try {
          BufferedReader br = new BufferedReader(new FileReader(filename));
          String line;
          while((line = br.readLine()) != null) {
          vec.add(line);
          for (int i = 0; i < vec.size(); i++) {
          num[i] = (int) vec.get(i);
          System.out.println("Number=" + num);
     catch(IOException e) {
          System.out.println("error");
     return num;
Maxsum.java:22: cannot resolve symbol
symbol : class num
location: class Maxsum
     num = new num[vec.size()];
^
Maxsum.java:30: inconvertible types
found : java.lang.Object
required: int
          num[i] = (int) vec.get(i);
How do i initialize the array?if i do not initialize it, there'll be array not initialized error also..How do i convert the String to int?
