toHexString(int i) unnecessary ?

Why wrapper class Integer has 2 methods to convert a base 10 int to a Hex (base 16) string ?
static String toString(int i, int radix)
static String toHexString(int i)
eg: to convert 15 to F
Integer.toHexString(15) returns f
Integer.toString(15, 16) also returns f

If we already have the generic method
static String toString(int i, int radix)
why do we still need
static String toHexString(int i) ?
Doesn’t the former makes the latter unnecessary ?

For conveniance, in case you do not want to have to specify the default radix each time you use the method.
