Play WAV files with Java

The following simple application demonstrates how to play back a WAV audio file with Java APIs.
The key step is to specify the correct parameters and create an AudioFormat object.

Playing with Big Integers using Java BigInteger

The BigInteger class in java.math package allows to perform arithmetic operations on large numbers which do not fit into the Java primitive data types. The BigInteger class is particularly useful in cryptography operations where large prime numbers play a pivotal role.

The following snippet, which calculates the smallest factor of an integer (not in the most efficient way) gives a simple demonstration of fundamentals of using BitInteger instances in a program.

A key point to remember is the immutable nature of BitInteger instances.

Inter Process Communication: Windows NamedPipes & Java Applications
