how to convert binary string to int?

[bob2000]

Hi,

I need to know how you convert a binary string into its integer variable type equivelant.

For example,
String s="1001" (which is actually the number 9 in binary base 2)

I want to know how to convert it into an int or long variable type.
Is there a method that will take the binary string ie. "Integer.convertBinaryString()" that will take my binary string and convert it into the Base 10 integer equivelant?

Ive heard of the Integer.Decode() method, but I think it only works for converting base 8 and base 16 strings into the integer equivelant. I dont think it converts base 2 strings into int. Does anyone know how to convert a base 2 number in string form into the base 10 integer equivelant?

String binaryString = "1001";
int base = 2;
int decimal = Integer.parseInt(binaryString, base);

They call the base "the radix" in the API docs.
