binary - Java Integer parseInt error

Question

I have following problem:

I want to convert some Binary Strings to an integer:

eargb = Integer.parseInt(al + re + gre + blu, 2);

but I get following exception. Why?

java.lang.NumberFormatException: For input string: "11111111111000101000100111111010"

Answer 1

Your number (4,293,036,538) is too large to fit in a signed int (which has a range of -2,147,483,648 to 2,147,483,647).

Try using a long instead. This has a larger range.
