Java String to Integer Conversion throws NumberFormatException

I want to cast a string (binary digits) to an Integer like this:

Integer.parseInt("011000010110")

I always get an NumberFormatException. Is the number of digits too high?

All of Java's number classes are base 10. However, I found these two options here:

working with binary numbers in java

The BitSet class, or a way to declare an int as a binary number (Java 7+). The latter may not work for you depending on how you're obtaining these numbers.

Yes, the string "011000010110" is about 11 billion, which is higher than the maximum representable int, Integer.MAX_VALUE, 2,147,483,647. Try

Long.parseLong("011000010110")

Or, if you meant it as binary, pass a radix of 2 to parseInt:

Integer.parseInt("011000010110", 2)
