NumberFormatException raised

hi,iam converting string to integer using Integer.parseInt().
But it is giving NumberFormatException.Can any help me by
seeing below code.

try{
String s="venkat";
int i=Integer.parseInt(s);
System.out.println(i);
}catch(NumberFormatException e)
{
System.out.println("NumberFormatException: " + e.getMessage());

Code:

---

String s="venkat";
int i=Integer.parseInt(s);

---

what integer is "venkat"? What number would you expect to see for this string?
Wouldn't it make much more sense to try to parse a number string to int? Something like,

Code:

---

String s="123";
int i=Integer.parseInt(s);
