#27756 — how to use unsinged long in java

hi 
I wnat to store 20141231246023 but long is out of range in it.
how to save value in this range.
is there any unSigned long available??

I was trying unSigned long but not working ..

No.

That should not surprise you.

Would 'java.math.BigInteger' help you?

It surprises me how many people apparently learn to program by randomly
typing words into their text editor until one turns out to coincidentally
be something the compiler recognizes. It's like learning a second language
by pressing random letters until Word stops putting red squigglies under a
word.

Not really. If someone have experience in C++ or other languages, it is 
natural to try same type names, expecting them.

Sure, insofar as it's "natural" to try anything utterly stupid.

Here's what's natural to actual computer programmers: looking it up.

For God's sake, the primitive type names are the most, well, primitive facts about the language!

And you make excuses for that baloney?

There's something unnatural there.

the primitives are listed at http://mindprod.com/jgloss/primitive.html
the keywords are at http://mindprod.com/jgloss/keyword.html

Use the index to get a novice-friendly intro to each keyword.

???

long is signed 64bit: -9223372036854775808 ... 9223372036854775807

If that's too small, use java.math.BigInteger or roll your own
fixed size type consisting of two or four or eight long.

     No, the value is well within the range of `long'.  The problem
is that it's *not* within the range of `int', so you cannot write
the value as an `int' constant.  Use 20141231246023L to write a
`long' constant.

     No.

you can store an unsigned long, but you can't do unsigned arithmetic.

see http://mindprod.com/jgloss/literal.html
for how to do long decimal and hex literals.

As others said, long is fine.

But I really cannot recommend to use integers for human readable time 
stamps. SAP does this and it is the source of problems all the time.
- The types provides the operators +, -, *, /, % without any reasonable 
result.
- It can represent inconsistent time stamps like Feb 31th.
- Accessing the fields cause the same number of divisions than with a 
linear representation like with java.util.Date.
- And some visualizations end up with 20,141,231,246,023 which is 
entirely unreadable.
