Question

See how int a and int b have the prefix “0x” before the hex value? I want to make more of these from a string. I tried to use parseInt from Integer, but I get a NumberFormatException. Can anyone help?

int a = 0xA;
int b = 0x4;
String f = "0xF";    
int d = Integer.parseInt(f, 16);

I want “int d = 0xF”

Answer 1

How about this?

String f = "0xF";    
int d = Integer.parseInt(f.substring(2), 16);
System.out.println(d);

OUTPUT:

15
