Working with bytes

[Cassiano]

I need to convert 11011101 to a byte but when I try:

Byte.valueOf("11011101", 2);

Error:

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: Value out of range. Value:"11011101" Radix:2

What I have to do to decide this problem?
How I decide this problem with the band of representation of a byte?

But it's telling you that the value is out of range. It's too big to be stored as a byte.

Hi

Byte data type can store maximum 127 decimal number value. If you try to store more than that it wil show errors at compiler.

If you numbr is in binary and you wants to convert it in decinal then . I think you should read a begainners level book.

I know that, but i'd like to know if have a possibility to represent a decimal > 127 in just 1 byte, how I can do that? This is possible ?

Theoretically: 1 byte have 8 bits, so can be 11011101 for example.

I hope you are not confusing changing to binary and changing to byte.

@OP: note that you can cast an int back to a byte in which case the lowest
eight bits are stored in the byte. (hint, hint ;-)

kind regards,

About time you showed up.
You have no idea what mess I've been getting myself into.

What's the mess then? I saw a very slow thread going on about Exceptions, but
that was about it. This thread's problem is almost solved thanks/due to my all
spoiling hint ;-)

kind regards,

Jos (still got work to do but I'll take a peek here now and then)

You haven't seen the private class declaration thread then.

Nope, I'm afraid not; what's the thread title? I'll take a look and see if I can create
an even greater mess out of it then ;-)

kind regards,
