What is Java Technology?

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Java is free to download for personal use. Java is also free for development:

Java Runtime Environment

Java Runtime Environment (JRE) version 8 is what you get when you download Java software from java.com. The JRE is the runtime portion of Java software, which is all you need to run.

Java Virtual Machine and JVM.

The Java Virtual Machine is only one part of Java software that is involved in running an application. The Java Virtual Machine is built right into your Java software download, part of the JRE and helps run Java applications.

The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries.

Java Developer Learning Path Start here with your taste.

A Java developer is a specialized programmer or you can say coder who teams up with software engineers to combine Java into business software, applications, and websites. A Java developer is responsible for

• Design, Implement and Maintain Java Application
• Involved in software analysis, testing, coding, and debugging
• Transform requirements into stipulations
• Recommending modifications to advance established Java application
• Develop technical designs for app development, etc.

Now all your java code should be built. So for building your Java project you must be aware of the different build tools. Some of the amazing tools that you can use for building your Java project are:

• Maven
• Gradle
• Ant

5) Servers

Once you have created your web application it’s time to deploy it. So you will be deploying your web application on the server so you must be aware of at least one server that you can work with. Tomcat is the most widely used server. Apart from that JBOSS is also used in many places.

• Tomcat
• Weblogic
• JBOSS
• WebSphere
• Jetty

6) Database

Database plays an integral role in creating a Java application as storing data is a crucial aspect. So if you work in any organization you have to work with databases. You have to write the queries to execute different operations on a database. So some of the topics that you need to learn are:

• Junit
• Mockito

8) Logging

There are different logging libraries are available in Java. So whenever you create the Java application you should log your errors or files to get information about what’s happening in the system. You must be aware of any of the following Logging libraries

• Log4j
• Log4j2
• Logback

9) Frameworks

There are a lot of different frameworks are available in Java. These frameworks foster easy debugging, extensive code reusability, improved code efficiency, and reduce the overall development time. So mentioned below are some of the Java Frameworks that you can learn:

• Spring
• Spring Boot
• Hibernate
• JSF
• GWT
• Micronaut

10) Keep Practicing

“Practice makes a man perfect”. So keep learning, practicing, and stay updated.

Java Editions

The Java Programming Language has the following defined editions that it supports: Thus, it is clear that Core Java is the part of Java SE and Java SE is the foundation for all other Java editions.

Java SE (Java Standard Edition)

The Java SE is a computing-based platform and used for developing desktop or Window based applications. Thus, core Java is the part of Java SE where the developers develop desktop-based applications by using the basic concepts of Java where JDK (Java Development Kit) is a quite familiar Java SE implementation.

Java EE (Java Enterprise Edition)

Also known as Java 2 Platform or J2EE. It is the enterprise platform where a developer develops applications on the servers, i.e., the enterprise development. This edition is used for web development.

Java ME (Java Micro Edition)

It is the micro edition that is used for the development of mobile phone applications. Thus, for the development of mobile applications, one needs to use Java ME.

Start with basic understanding & practice regular.

If You are using GPS read this

.

Like the Internet and smartphones, GPS is an essential element of the information infrastructure. GPS receivers are very simple electronic devices. GPS technologies commonly accepted in society. The price of GPS devices has dropped. GPS works by timing how long it takes the radio signals from its satellites to reach a location on earth.

.

Distance = Travel Time x Speed of Sound

GPS benefits over previous land-based navigation systems is that GPS works in all weather conditions. GPS system streamlines supply chains and vehicle movements. A GPS system in a vehicle, boat, plane or backpack or any other vehicle ensures that you are never lost. We have many more advantages of GPS system.

.

Disadvantages of GPS

Privacy Issues

GPS devices can be used to know the location of people without their knowledge. In today scenario smartphone have inbuilt GPS devices. In case your important application on phone requires GPS access. You will make it enable. In this case you are not enabling your device for only required application but for operating system. Any other application having permission can use it.

.

Commercial Exploitation

When GPS is combined with internet technology, social media or mobile phone apps, it can be used by commercial organizations to track someone’s travel or movement and misuse this information to collect data on a person’s buying habits, or target them with advertising based on their location.

.

Local Knowledge must

Using solely GPS technology means that you can miss out information that might be important for your movement. For instance, If road is temporary blocked, whether there are any scenic views, or whether

.

Limited battery life

Maximum GPS devices depend upon battery. In case of battery failure it will completely down may be at that time urgently required.

Your every action on internet is noted and stored

Not very far in the past, who was visiting sites and for what reason was basically a puzzle. Website admins put counters on pages to follow how frequently individuals “hit” the page—that is, visited, downloaded a record, or some other action—however that was the degree of the understanding. Genuine web investigation capacities were restricted to huge organizations that could bear to burn through thousands of Rupees / dollars every month on programming to track and write about web movement.

Today, there is a wide range of web metrics measuring and tracking applications available even Free and effective and search engines are using them. Maximum search engines are noting and storing the data of actions in private mode. Few tools of analytics are even freely available for users also.

DuckDuckGo is an Internet privacy company that provides tools and technologies to help people control their personal information online. One of these tools is DuckDuckGo Search, a private search engine that allows you to the search the web without being tracked. Another is DuckDuckGo Privacy Browser, a mobile browser that provides all the privacy essentials needed to browse the web more privately. For more information about duckduck go please visit the official website duckduckgo Dot COM.

Publication Title: Analysis for Improving Intrusion Detection System in Wireless Network

Abstract:-First of all Wireless is word that defined as ”having no wires. Wireless is the term used to define in a computer network where there is no physical wired assembly between sender and receiver, but somewhat the network is subordinated with radio waves and microwaves to maintain transportation. Wi-Fi describes communications in which electromagnetic carry the signal over part or the entire communication path. Wireless networking utilizes specific tools such as NICs, APs and routers instead of wires for linking the network.

WLAN as a result referred to as wireless fidelity (WI-Fi).This paper especially relevant to focus on detecting intrusion or jarring (abnormal) behavior of nodes in WLANs using signature based Intrusion detection method. We explore the security susceptibilities of 802.11 and numerous intrusion detection methods. This paper, indicates the developing history of the Wireless Intrusion detection system (WIDS), and then sum up the connected work on Wireless Intrusion Prevention System (WIPS) through a RF jamming method.

Keywords
