New-age IT skills can double your pay

If you have some of the new-age tech skills, not only are you likely to be hired much faster, you could also earn far better salaries.

Terms like R, Julia, Hadoop, Scrum Master and DevOps may sound alien to most people, but these are some of the hot skills that companies are looking for. A youngster who has just started out and has learnt R, a popular programming language used for statistical computing to derive insights from data, gets an average salary of Rs 8 lakh a year, according to data, an online education provider of professional certification training or Certified Java Training in Mumbai. In comparison, the average salary for a regular fresher in an IT company is Rs 3.5 lakh.

A mobile app developer or a Hadoop developer (Hadoop is a programming framework that supports the processing of large amounts of data in a widely distributed computing environment) can also get a similar salary. Age is not a factor here, it just depends on whether you have picked up the skills.

These skills reflect the big shifts in the kind of software being used inside large firms today. This has been driven by the dramatic increase in mobile devices, the big jump in digital data, the need to analyze this data, and the phenomenon called cloud computing -- use of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer. Added to this is the emergence of what is called the internet-of-things - the trend to get everyday objects, be it a toaster, fridge, light fitting or an industrial machine, to communicate their status with remote computers or Smartphone’s or even with one another.

"These are deep technology shifts changing the game for businesses. Five years ago, Java, C++ were sought-after skills, but IT companies are today looking at diversity in their tech talent pool to improve business conversation with their customers," said Kashyap Dalal.

Sachin Gupta, co-founder of online programing platform HackerEarth, said R programing provides a very good way to quickly prototype and visualize data. "Its libraries in statistics and mathematics give a lot of power to data scientists to quickly manipulate data. Julia, which started as a scientific computing language, is gaining traction in the data sciences domain. Python, a programing language for data sciences, continues to be the language of choice after R because of its versatility," he said.

Dalal said that a Hadoop skill set will get a developer 25% higher compensation compared to just having a Jgava skill set. An iOS developer can expect way higher salaries than an Android developer, partly because such skills are in short circulation. Gupta's data showed that an iOS developer with 2-4 years of experience gets paid between Rs 12.5 lakh and Rs 25 lakh, while an Android developer with a similar experience gets paid Rs 15 lakh to Rs 18 lakh.

Gupta said there's a lot of demand for full-stack developers, the supercoders who understand database programing, have knowledge of HTML, CSS (which describes how HTML elements are to be displayed on screen) and JavaScript and have experience in cloud deployment solutions like AWS.

Working of String – Java Course

Java is platform independent. Java Course helps to develop career in Java Industry. Get Training and learn to develop projects in Java.  

Following is the one part of Java Course. – Working of String

According to Oracle String in Java are sequence of characters and are represented by a class java.lang.String.

So in simple words String in Java are objects.

Declaration for String class looks like this

public final class String extends Object

String in Java are of nature Immutable as they are declared as final.

String can be declared in multiple ways in java

For example

String str="Java";

In this case str is a String literal as it is declared directly using = sign.

While execution JVM creates a String object and store it in Object Heap.

Other way of Declaration

String s=new String("Hello");

or

char[] charArray=new char[]{'s','u','c','c','e','s','s'};

String s1=new String(charArray);

An important concept which many people don't take notice of is the following situation.

String str="java";

str=str.concat("withz.in");

System.out.println(str);

String is of nature final and final objects can change their reference.

So what happens when we print this and how many String objects are created in this process.

On the very first line.

String str="java";

JVM created a new object with value "java".

When we concat other String "withz.in" in the original String str.

But as String is of nature final it cannot make changes in the same object reference, hence it first creates a new object "withz.in" and then concat the other two Strings and create a new String "javawithz.in" and we have used assignment operator

str=str.concat("withz.in");

Now str points at the third object created and first two objects lies unidentified in Heap and when we print we print it we get output as "javawithz.in"

Now let us take another example for understanding the same concept

String str="java";

str.toUpperCase();

System.out.println(str);

Now in this case when the first line got executed JVM created a new String object "java" and str was pointing at the same object.

Then we did

str.toUpperCase();

This created a new Object with value "JAVA" but as we haven't used any assignment operator str is still pointing at old reference and not the new.

So when we print it we will get "java".

Introduction to Class in Java

Java Class

·         Class is a template or blue print which is used to describe an object.

·         Class is one of the most important and misunderstood concept.

Class has got various definitions,

- Class is user defined data type.

- Class is an Abstract Data Type(ADT).

- Class is collection of variables and methods.

All the given definitions are really true but for a person who have just started to understand Java it becomes a bit tedious to understand.

Class is just a planning or a design on which object referring to it will be built upon.

Have you ever imagined why Fish cannot fly or Eagle cannot swim?

Answer is very simple because flying is not a characteristics of Fish and swimming is characteristics of Eagle.

If you understand this understanding concept of class will become easier.

Remember a class is made up of following content and all of this are optional, because if you try to do something like this.

class Demo

{

}

It will compile fine.

So a class can be made up of,

1) Variables

2) Methods

3) Constructors

4) Inner Classes

So assume for example if a class A contains certain methods m1(), m2(), m3().

It will be only able to access those methods and not any other methods (Assuming class has not inherited any other class other that java.lang.Object)

So in simple words "AN OBJECT OF A CLASS CAN ACCESS ONLY THOSE METHODS WHICH ARE DEFINED INSIDE IT'S CLASS, NOTHING MORE OR NOTHING LESS".

So as discussed, class Eagle does not have a variable fin and method swim() hence it cannot swim but same are the variables and methods of Fish, hence it can swim().

Same way Fish does not have variable wing and method fly() hence it cannot fly, but same are the variables and methods of Eagle so it can fly.

Now let us have a look at technical aspect of Class.

class is defined by a keyword class

class Fish

{

 int fin;

  Fish()

 {

  System.out.println("Inside constructor of Fish");

 }

 public void swim()

 {

  System.out.println("Swim of Fish");

 }

}­
