Question

I am using the following:

int i = Integer.parseInt(args[2]);

Are there any other ways to get an integer from a string? If the number is really small as it is then doe the Byte and Char objects provide something similar?

Answer 1

Yes. There’s:

Byte.parseByte(s); -- parses a Byte from a String
Short.parseShort(s); -- parses a Short from a String

And for larger numbers there’s:

Long.parseLong(s);
-- Float is an imprecise representation of a floating point number using 32 bits
Float.parseFloat(s);
-- Double is an imprecise representation of a floating point number using 64 bits
Double.parseDouble(s);
-- BigIntegers is an integer of arbitrary size as is accurate
new BigInteger(s);
-- BigDecimal is a floating point number of arbitrary size as is accurate
new BigDecimal(s);
