Convert java.lang.String to binary

Hi - I have Strings like these two: "1111100001000111111010" and "111" that
I am reading in from a file.

Is there a standard class I can use to convert them to longs 4067834 and 7
respectively. I don't want to reinvent the wheel.

Thank you
Hort

Long.parseLong(String s, int radix)
Integer.parseInt(String s, int radix)

(etc)

See JavaDocs re 'radix'..

<sscce>
public class LongBinary {
public static void main(String[] args) {
String bin = "1111100001000111111010";
long l = Long.parseLong(bin, 2);
System.out.println(bin + " is " + l + " in base 10.");
}
}
</sscce>
