"Implementation of Units of Measurement services. A coordinates module compliant with OGC/ISO specifications for the development and deployment of geographic applications. A rigourous mapping of mathematical structures (e.g. Group, Ring, Field, VectorSpace ) to Java interfaces. A linear algebra module, which includes a first (and I believe unique) parameterized matrix class capable of resolving linear system of equations involving any kind of elements (e.g. Complex, ModuloInteger, RationalFunctions) A functions module for symbolic calculations and analysis. Different types of numbers such as real numbers of arbitrary and guaranteed precision, or the always exact rational numbers. Support for exact or arbitrary precision measurements (also strongly typed). Support for Standard , Relativistic , High-Energy , Quantum and Natural physical models. A monetary module for precision-guaranteed calculations and currencies conversions."

Do you Want To know About method Overloading in Java? We provide you best notes on method overloading with great examples which can easily understandable for everyone.There are two ways to overload the method.

If a class have multiple methods by same name but different parameters, it is known as Method Overloading. If we have to perform only one operation, having same name of the methods increases the readability of the program.

Encapsulation is a process of wrapping code and data together into a single unit. It is a way to achieve data hiding.

There are two types of modifiers in java: access modifier and non-access modifier. The access modifiers specifies accessibility (scope) of a datamember, method, constructor or class. There are 4 types of access modifiers: There are many non-access modifiers such as static, abstract, synchronized, native, volatile, transient etc. Here, we will learn access modifiers.

A package is a group of similar types of classes, interfaces and sub-packages. Package can be categorized in two form, built-in package and user-defined package. There are many built-in packages such as java, lang, awt, javax, swing, net, io, util, sql etc. Here, we will have the detailed learning of creating and using user-defined packages.

An interface is a blueprint of a class. It has static constants and abstract methods. The interface is a mechanism to achieve fully abstraction in java. There can be only abstract methods in the interface. It is used to achieve fully abstraction and multiple inheritance in Java. Interface also represents IS-A relationship.

Runtime Polymorphism. Let's learn what is runtime polymorphism with suitable example.

Instance Initializer block is used to initialize the instance variable.Let's see what is its advantage over instance variable.

super keyword. The super is used to refer the immediate parent class object. There are three usage of super. Let's see:

The covariant return type specifies that the return type may vary in the same direction as the subclass. Before Java5, it was not possible to override any method by changing the return type. But now, since Java5, it is possible to override method by changing the return type if subclass overrides any method whose return type is Non-Primitive but it changes its return type to subclass type.

Normally, array is a collection of similar type of elements that have contigious memory location. In java, array is an object the contains elements of similar data type. It is a data structure where we store similar elements. We can store only fixed elements in an array.

A class that is declared with abstract keyword, is known as abstract class. Before learning abstract class, let's understand the abstraction first. Abstraction Abstraction is a process of hiding the implementation details and showing only functionality to the user.

In this page, we will learn how to write the hello java program. Creating hello java example is too easy. Here, we have created a class named Simple that contains only main method and prints a message hello java. It is the simple program of java.

In this page, we will learn about the objects and classes. In object-oriented programming, we design a program using objects and classes. Object is the physical entity whereas class is the logical entity. A class works as a template from which we create the objects.

Let's learn what is naming convention and what are its benefits.
