Why am i getting NumberFormatException

[ashwin bhawsar]

I tried out the following :

int a=Integer.parseInt("11",2);
System.out.print(a); // output 3

int b=Integer.parseInt("015",8);
System.out.print(b);// output 13

int c=Integer.parseInt("0xf", 16); // NumberFormatException


I did not get why i am getting the exception.

From the documentation:

Parses the string argument as a signed integer in the radix specified by the second argument. The characters in the string must all be digits of the specified radix (as determined by whether Character.digit(char, int) returns a nonnegative value), except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value.

So you want

int c=Integer.parseInt("F", 16); // 15
