Getting integers from text file and work on array list in java -

i have text file contains:

" have 3 apples , 1 banana.
all people have 4 cars @ least."

i want read .txt file , integers it.i strore integer variables in arraylist.

public class dedede {     public static void al() throws exception {          file f = new file("c:\\users\\sony\\desktop\\456.txt");          try {             filereader islem = new filereader(f);              char data[] = new char[(int) f.length()];              islem.read(data);             string metin = new string(data);              arraylist<integer> yapi = new<integer> arraylist();              stringtokenizer s = new stringtokenizer(metin);              string dizi[] = new string[s.counttokens()];              int = 0;             while (s.hasmoretokens()) {                 dizi[i] = s.nexttoken();                 i++;             }              (int c = 0; c < dizi.length; c++) {                 if (integer.parseint(dizi[c]) > 0) {                     yapi.add(integer.parseint(dizi[c]));                 }              }              system.out.println(yapi);         } catch (ioexception e) {             e.printstacktrace();         }      }      public static void main(string[] args) throws exception {         al();     } } 

try this:

static arraylist<integer> al = new arraylist<integer>();  public static void main(string[] args) {      try {         file file = new file("c:\\users\\sony\\desktop\\456.txt");         bufferedreader in = new bufferedreader(new filereader(file));         string s;          while ((s = in.readline()) != null) {             findinteger(s);         }         in.close();     } catch (ioexception e) {         system.out.println("file read error: " + e.getmessage());     }     system.out.println("integers: " + al); }  private static void findinteger(string s){     string [] parts = s.split(" ");      (int = 0; < parts.length; i++) {         try{             int j = integer.parseint(parts[i]);             al.add(j);         } catch (exception e){}     } }
