How to use the BigInteger constructor and method?

I am so confused about on how to use the public constructors and public methods, can anyone show me some example? Thanks.

It should be something like:
BigIntger x = new BigInteger("-123456789012345678901234567890");
BigInteger absX = x.abs();
float floatX = x.floatValue();

simple

Any particular public method you're confused about? The Javadoc for BigInteger, as you have quoted in your post explains everything related to this class.

I am confused about the public constructor, BigInteger(int bitLength, int certainty, Random random), and public method, probablePrime(int bitLength, Random random). My intention is generating a large random prime number.
