Welcome to the World of JAVA Programing!!!

A Java program is mostly a collection of objects talking to other objects by invoking each other's methods. Every object is of a certain type, and that type is defined by a class or an interface. Most Java programs use a collection of objects of many different types. Our objective is to come up with java example programs for each and every class provided by java documentation, which can be very much helpful for java beginners.

Knowledge Center block on right side of the page will randomly posts some quick information on java language. It could be quick learning for new java learners.

Core Spring Examples
The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of...
Restful Web Service Examples
RESTful web services are built to work best on the Web. Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability...
Collections & Util Package
A collections framework is a unified architecture for representing and manipulating collections. Java Collections Framework reduces programming effort, increases program speed and quality, allows interoperability among unrelated APIs, fosters software reuse.
Data Structures
A data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. Data structures provide a means to manage large amounts of data efficiently. efficient data structures are a key to designing efficient algorithms.
Java Interview Programs
We have collected list of java interview programs from few software engineers and also with my personal experience. In this section, we are trying to give you the best solutions for these problems. Good interviewers are more interested in your ability to code.
Java Sorting Algorithms
A sorting algorithm is an algorithm that puts elements of a list in a certain order. The most-used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the use of other algorithms such as search and merge...
Java JDBC Examples
JDBC stands for Java Database Connectivity. JDBC API is a collection of classes and interfaces, which help a Java application to connect to SQL based relational databases by abstracting vendor specific details of the database. JDBC enables Java developers to connect to...
Java Annotations Examples
Java Annotations are also called Metadata. Annotations are introduced with JDK 5 onwards. Annotations allows us to add some form of metadata information into our source code, but it doesnot change the execution flow of the program. These annotations...

Procedural Vs Object-oriented Programs
In procedural program, programming logic follows certain procedures and the instructions are executed one after another. In OOP program, unit of program is object, which is nothing but combination of data and code.

In procedural program, data is exposed to the whole program whereas in OOPs program, it is accessible with in the object and which in turn assures the security of the code.
