JAMA: Java Matrix Package. Background JAMA is a basic linear algebra package for Java. It provides user-level classes for constructing and manipulating real, dense matrices. It is meant to provide sufficient functionality for routine problems, packaged in a way that is natural and understandable to non-experts. It is intended to serve as the standard matrix class for Java, and will be proposed as such to the Java Grande Forum and then to Sun. A straightforward public-domain reference implementation has been developed by the MathWorks and NIST as a strawman for such a class. We are releasing this version in order to obtain public comment. There is no guarantee that future versions of JAMA will be compatible with this one. A sibling matrix package, Jampack, has also been developed at NIST and the University of Maryland.
Capabilities. JAMA is comprised of six Java classes: Matrix, CholeskyDecomposition, LUDecomposition, QRDecomposition, SingularValueDecomposition and EigenvalueDecomposition. Example of Use.

Java is amultithreaded programming language which means we can develop multithreaded program using Java. A multithreaded program contains two or more parts that can run concurrently and each part can handle different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs.
By definition multitasking is when multiple processes share common processing resources such as a CPU. Multithreading extends the idea of multitasking into applications where you can subdivide specific operations within a single application into individual threads. Each of the threads can run in parallel. The OS divides processing time not only among different applications, but also among each thread within an application. Multithreading enables you to write in a way where multiple activities can proceed concurrently in the same program. Life Cycle of a Thread: A thread goes through various stages in its life cycle. Above-mentioned stages are explained here: Multithreading Programming Tutorial. Jepp - Java Embedded Python. Javarevisited: FIX Protocol, tibco,unix and java tutorial with example.
