"BigInteger supports arbitrary-precision integers" .What does this statement mean actually?

It means that you can try to compute numbers like (BigInteger.TEN.pow(Integer.MAX_VALUE)).pow(Integer.MAX_VALUE) and your program will actually try to do it.  My computer has been running at 100% CPU for the last 10 minutes doing the calculation...

If you need to compute something to 37 decimal places, it'll do it! Whee!

I wonder if BigInteger supports decimal places.

If I recall correctly, the primitive int type uses 4 bytes and long uses 8 bytes. This means that the largest value you can hold in an int is just over two trillion and the largest value in a long is just under 2*10^19. If you need to store numbers larger than this, you can use BigInteger. That is what the statement means.

Oops, typing faster than I'm reading again. In my "first love" langauge, REXX, arbitrary precision includes decimal places.

That's what BigDecimal is for.
