Java BigInteger.pow() is a method in the Java BigInteger class that raises a BigInteger to the power of an integer exponent. It is used for performing exponentiation with arbitrarily large integers, which is common in cryptography, scientific computing, and algorithms requiring large-number arithmetic. Introduced in Java 2004 with Java 5, pow() enables precise calculations beyond the limits of primitive types like Java int or Java long.
