What is Java and Java Web Services
Java, developed by Sun Microsystems and released in 1995 is a high-level programming language capable of running on a variety of operating systems (OS)-Mac, Windows, and Unix. It is an object-oriented language that is simple, secure and architecture neutral. Web services enable communication between applications, OS, and devices in a network. Java is Web Services are platform neutral, and language neutral. There are primarily two types of Java Web Services – JAVA-WS for SOAP and JAVAS-RS for ReSTFUL.

Web Services Introduction:
This section gives an overview of web services and the role it plays in enabling communication between devices, applications, and OS across networks. There is mainly two type of web services- SOAP (Simple Object Access Protocol) and ReST (Representational State Transfer). The major components of web service- SOAP, UDDI, and WSDL are covered. The concept of Service Oriented Architecture (SOA) is also provided.
Java XML: This section also provides a comprehensive view of XML (Extensible Markup Language) and the role played by Java in a communication of data between applications XML is a simple, and text-based language that enables storing and transferring of data. The advantages and disadvantages of using XML over HTML, Java DOM Parser, Java Sax Parser, Jax Parsers and how they access and modify data, context, structure and style of XML documents are dealt in this section.
Introduction to Java:
Java is a high-level object-oriented programming language and a platform used for web, embedded systems, mobile applications, enterprise applications, desktop applications such as acrobat reader, media player among others. Features of Java are dealt in this section-simple, secure, platform independent, distributed, high performance, robust and portable. Java Runtime enables users who want to just run programs but is not interested in development.
The concept of data types and variables are dealt in this section. Different data types-Primitive Data Types and Reference/Object Data Types, variables are covered. Variable is a reserved memory location which is assigned according to the data type- integers, decimals, characters. Instance variables, local variables, class variables are covered in this section.
Java Program Execution
Java editors are used to writing, create and compile codes online, it helps in editing code online and is a free tool. Java Development Kit (JDK), Java Virtual Machine and Java Runtime Environment are dealt in this section. JDK contains Java Runtime Environment (JRE) and JVM ()Java Virtual Machine.
Java Arrays are data structures in Java which groups variables of the same type together. For using array in a program, the program should specify which array can be referenced by a variable.
As with any programs, Java follows a basic syntax- it is case sensitive hence’ Hi’ and ‘hi’ will have different meanings, class names should have the first letter in upper case. There are rules with respect to program file name, method name and class names. Java attributes are fields that can be accessed directly. Java Enum is data types with a fixed set of constants and available on JDK. Defining Java Enum, initializing specific values, switch statement are covered in this section.
Classes and Objects:
This section covers a vast area of classes and objects. Classes are a blueprint for the creation of objects. Just as in real life we have several objects around us, Java too has objects with certain qualities. Every class has constructors, and new objects lead to new constructors. Each class can have more than one constructors. Constructor codes, argument constructors are covered in this topic.
Data Types –Primitive Data Type, Object Reference Data Types. Primitive Data Types: Byte, Short, Int, long, float, double, Boolean, Char. Reference variables are access objects created using defined constructors.
This section covers local variables, instance variables, classic variables with examples of variables. How local, instance and class/static variables differ from each other and where they are defined. Local variables are seen in methods, blocks, and constructors while an instance is defined only in class and class variables are declared as static variables in a class.
This section deals with the definition and functions of modifiers. They are keywords added to definitions with the objective of changing their meaning. Two types of modifiers –Access Control Modifiers and non-access modifiers. Access control is used to set access for classes, methods, variables, and constructors while non-access is used for other functionalities.
Java uses several operators to manipulate variables and they are dealt in this section: Arithmetic, relational, logical, assignment, bitwise, assignment, misc operators.
Loop control in Java:
Programming languages have the challenge of executing repetitive tasks or some done sequentially or based on conditions. Loop statements are used to execute a statement several times if some criteria are met. Loop types are – While Loop, for Loop, do..while loop. Loop control statements help Java program change track from its normal path. Java supports break statement and continue statement. Enhanced for loop are also covered in this section.
Decision Making structures in Java:
Decision making structures are executed when one or more condition is satisfied. Decision-making statements- if statement, if…else statement, nested statements, switch statements are covered in this section. How decision making works in programming.
Java Number Class:
This section deals with Number Class and Number Methods. Java uses wrapper classes where objects have to be used instead of data types- Wrapper classes-number, byte, double, float, integer, short, long. Objects have values of primitive data types and it helps in converting objects into data types called boxing… When a value of primitive data type is passed on to the constructor of the wrapper, the wrapper object is converted back to a primitive type called unboxing. Number methods-xxxValue, compareTo, equals (), value of (), toString (), ParseInt (), bass, ceil (), floor (), rint (), round(), min (), max (), exp (), log(), pow (), sqrt ()etc.
When Java needs to use data instead of primate data types, it has the wrapper class character, character class has methods to manipulate characters. The section introduces characters with examples.
Java String Class:
Strings are objects which consist of a sequence of characters. The string class enables users to create and manipulate strings. Compilers generate objects when it sees string literal in programming code. The section deals with string length, concatenating strings, creating format strings, string methods.
This section deals with the data structure in Java called arrays. It is a collection of data with variables of the same type. Topics covered are declaring array variables, a creation of arrays, processing arrays, passing arrays to methods, for each loop, returning the array from a method and the arrays class. Date and time: The provision of Date Class in Java, data comparison, getting current date and time
This section deals with the concept of regular expressions- which are a special sequence of characters to help in matching or finding other strings/set of strings. It is used to search, manipulate, edit data. The Java Regex package- pattern class, matcher class, pattern syntax exception, capturing groups, regular expression syntax, matcher class methods, replacement methods, start and end methods are covered.
Java methods and IO:
Streams for creating input and output, stream- a sequence of data, InputStream, Output Stream, types of streams- byte streams, character streams, standard streams, reading and writing files, FileInput, File output streams, file navigation, directories, creating directories.
Inheritance – one class acquiring the methods and fields of another. Yes Class, subclass, extends Keyword, sample code, super keyword, superclass constructor, Instance of Keyword, polymorphism- the ability of an object to take many forms, interface, abstraction –hiding the implementation details from the user, packages. interface, packages, encapsulation, overriding are all covered in this module.
This section introduces the concept of collections- dynamic arrays, linked lists, trees and hashtables to work in a similar manner. Standard implementations- LinkedList, HashSet, TreeSet. Collection interfaces, collection algorithms, iterator, comparator, representing and manipulating collections.
Application servers, J2EE, components, J2EE services and API, JSP example are covered in this module. Application servers enable desktop applications and desktop connections to run. J2EE is a platform independent and used for creating and deploying web services. They contain APIs, protocols, and functionalities for developing applications.
Tiered applications in J2EE
Web clients, tiered applications, container types, J2EE model are covered in this module
