Java Program to convert hexadecimal number to decimal number

Use the parseInt() method with the second parameter as 16 since it is the radix value. The parseInt() method has the following two forms.

static int parseInt(String s) static int parseInt(String s, int radix)

To convert hex string to decimal, use the 2nd syntax and add radix as 16, since hexadecimal radix is 16.

Integer.parseInt("12", 16)
