Programming languages are going to change our future – well, they already are! – and are going to be used for more astounding apps, beautiful websites and software products than we can ever imagine. There are many programming languages out there, from C language to Python, but Java is popular because it can be easily customized and is considered very versatile. In 2019, TIOBE Index ranked Java as the top programming language, meaning that developers, programmers, app and website owners all need to be able to use Java as their mainstream language. Java is used by many companies, large and small, from Google and Amazon to niche small businesses. Becoming a seasoned Java developer will put you in the frontline to work with any client you could want – have we convinced you yet of the importance of Java as a skill to have?
This coming New Year, make it your resolution to do something truly valuable – become the best Java Developer you can be! But first, let’s check the Things that Java Developers Need to Know in 2020.So – you’ve decided to become a Java developer this 2020, or you already are one and are looking for ways you can improve. Here are the top 8 things Java developers need to know for 2020.

1. Core Java

"If you want to be a Java developer, you better have a sound knowledge of the inner workings of Java – you need to be able to grasp basic concepts like operators, arrays, loops and the general-purpose API’s such as java.math, java.oi, and java.lang. Keep practicing using Java and you will learn how to use it well, understanding all the limitations, possible problems and best design practices out there,” says Regan Knox, a tech writer at Writemyx and Britstudent.

2. Java EE

Java EE (Enterprise Edition) moves beyond the core Java to be more advanced, and allows you to work on projects like web development because it offers specific features like web services and distributed computing. There are technologies to learn here like Java Server Faces, WebSocket, Servlet and more.

3. JSP and Servlets

What you learn in Java EE can be taken further in what is known as Front End technologies such as CSS, HTML and JavaScript. You can then make mini projects based on particular subtopics, sharpen your programming skills and gain experience with JSP and Servlet. It’s important to keep up to date with new technologies and developments in the programming world!

4. Learn about Hibernate Framework and Spring Framework

In Java, Spring and Hibernate are the most famous frameworks around – Hibernate is used to map domain object-orientated models to relational databases, whilst Spring is used in Spring MCV, Spring Boot and Spring Cloud. By having a working knowledge of these frameworks, you’re in a much better position to work in a Java development company!

5. DevOps

Many Java developers are learning about DevOps (Docker and Jenkins) because more companies are moving to DevOps. DevOps is very fast and requires a good knowledge of tools and principles, but don’t be put off – it’s an invaluable skill in 2020. If you’re a Java developer with a passion for managing the environment, automation and improving the overall structure, DevOps is for you. There are even great courses like Master Jenkins CI for DevOps and Developers, which is a great place to start learning!

6. Git and GitHub

Nowadays, many companies are migrating their projects from SVN, CVS to Git, so it’s high time to learn and master it. Again, there are great guides out there like the Git Complete: the definitive, step by step guide to Git from Udemy. A good choice!

7. Java Versions 9, 10, 11 +

The problem with programming is that it is constantly evolving. It’s sometimes hard for developers and programmers to keep up to date! Java 9 has introduced new features such as modules, Jigsaw, Reactive Streams, Process API, HTTP2 client, JShell and API improvements. Further versions will have more to learn.

8. RESTful Web Service

“Some programmers say there are not many people out there with a working knowledge of Java and REST. So, being able to write REST API and implementing secure, scalable RESTful Web Service in Java by using Spring Framework is a great skill to have,” says Solomon Gibson, a from java blogger at 1day2write and Nextcoursework.

Natural disasters as we all know are the consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region. There is basically no human control over natural disaster. We cannot stop these natural disasters but what is in our hands is to be prepared for these. Also there are a lot of ways through which we can minimize the damage caused due to these natural disasters. Traditionally, natural disasters have been seen as situations that create challenges and problems mainly of a humanitarian nature.

There is no way to prevent or avert these natural disasters, though scientists do claim to have found the ways to predict these natural disasters but at most of the times they have failed to predict natural disasters causing some serious destruction. During the last few years, there has been an increase in the reports of natural disasters as well as destruction caused due to these disasters.

The tsunamis, hurricanes and earthquakes, which hit parts of Asia and the Americas in 2004/2005 are some examples of natural disasters in past few years and floods in the parts of Uttarakhand is a recent example of the destruction caused due to these natural calamities.

These calamities have led to displacement of a lot of people and heavy loss of life as well as property was also reported. Not just these few cases, natural disasters can be of many types which may include volcanic eruptions, tsunamis, foods, drought, landslides, or earthquakes etc. From past many years there has been a constant debate on the topic of natural disasters and the human role in the same.

A lot of human practices as well as rapidly growing developmental activities have been blame blamed for constant rise of these natural disasters like floods, hurricanes and tsunamis in past few years. One of the major causes of natural disasters has been attributed to the global warming, which has sparked debate analyzing what the effects may be. The reality at present is that we are experiencing an increasing number of natural disasters, and disaster preparedness is an area still to develop. Also along with the disaster preparedness there is a need to keep a check on developmental activities so that we could have a sustained environment.

Types of Natural Disasters

↳ Tsunamis
↳  Earthquakes
↳ Avalanches
↳ Volcanoes
↳ Landslides
↳ Floods
↳ Droughts
↳ Forest fires
↳ Hurricanes
↳ Thunderstorms
↳ Tornadoes
↳ Winter storms
↳ Heat Waves


What is Call for Code?

IBM has announced its Call For Code initiative, inviting startups and developers to solve problems related to natural disasters using cloud, AI, IoT, and blockchain platforms.

Call For Code was launched on May 24 by IBM chairman, president, and CEO Ginni Rometty during a keynote address at Viva Technology in Paris. The software giant has also committed to investing $30 Mn in the initiative in the next five years.

Developer teams can answer the call and register interest to compete in Call for Code, which begins officially on June 18 and closes on August 31.


How can people participate?

Call for Code invites developers to create new applications aimed at reducing vulnerability by mitigating disaster risk over the long run, forecasting impending threats to improve precautionary measures in the short term, responding to medical needs during the disaster, and improving the overall resiliency of communities to rebuild health services in the wake of major disruptions.
The $30 million, five-year investment award unites developers across the world to solve the planet’s pressing issues caused by natural disasters.
One team will win the first annual Call for Code Global Prize,  $200.000 USD supported by the United Nations Human Rights Office and the American Red Cross’ International team.
The winner will also earn several other awards that foster adoption of their application as an open source project (through the The Linux Foundation), scale its impact, and accelerate deployment in areas of greatest need.

First and second runner-up will receive :  $25,000 USD cash prize Invitation to the Call for Code Global Prize Event & Long-term open source project support from The Linux Foundation.

Winners will be announced at the Call for Code Global Prize Event and Concert, which will benefit UN Human Rights and the American Red Cross, and be held on October 13th, the United Nations International Day for Disaster Reduction.

Developers can learn more about this initiative at the Call for Code site. In addition, IBM will hold hundreds of events over the next three months in 50 cities around the world—San Francisco, Tel Aviv, Tokyo, and more—to help global developers address the complex problems stemming from natural disasters.
It’s my earnest hope that every developer, in some way, chooses to answer the Call for Code.
To get more insight into how critical of a moment this is for the developer profession, I encourage you to read the thoughts of IBM’s Vice President of Developer Advocacy, Open Source, and Technology, Angel Diaz. follow this link to participate in the challenge - https://ibm.co/2L4Gj9Q
