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");

 }

}­

3 reasons you should join a career training before you complete your last semester

By the time you were coming out of the hangover of New Year celebration, you realize that 4-5 months down the line you will be giving interviews and be in actual IT Industry. While many of the students opt for trying their luck of getting jobs directly in the campus, but as per the stats only 15-20% of the students get selected.

“75% of engineering and 80% of non-engineering graduates requires retraining after completing their college.”

Dr. A.P.J. Kalam in an interview to Arnab Goswami

You will be required to take your career oriented training to master the skills sometime in your life and the factor which decides it is the time when you opt for it.

Is joining such training before completing your last semester is good idea or not.

I will give you 3 simple reason supporting my point.

1.    Helps you crack your college campus interview easily.

2.    Final Year project become fun to make.

3.    Gives the edge of time compared to other students.

1. Helps you crack your college campus interview easily.

Getting placed in college campus is one of the great things that can happen in a student's career. Companies which come on campus doesn’t pick up every other student, they are looking for the best in the lot. Career Oriented Training like our 50 Days Java Training helps you get the extra edge over other students as such training courses also trains you for Interview. Cracking an interview is not a luck game but it is a science where a vendor is looking for a resource and you have be an asset for them. It is not possible that you will fit for all the requirements of all the companies that come for campus. But to excel where you fit requires hard work and training.

2. Final Year project become fun to make.

-       Final Year project is the mega event in life of all the graduation students. Finally all the things they have learnt during their graduation is put together and the final implementation of the project is created. But contrary to the beliefs 50% of the students just pick up the projects from some senior or worst scenario they buy it from some developer. Major reasons for doing so is really simple LACK OF KNOWLEDGE ABOUT CODING LANGUAGES AND IMPLEMENTATION. Our Training Program like Android and Java Developer Training helps you overcome that as this training programs covers a vast array of concept based implementation. Our Java Training encompass around 450 programs executed and Android Training covers development of around 50 apps with added benefit of Project Guidance for Graduation and Postgraduate students.

3. Gives the edge of time compared to other students.

-       Competition with others is not healthy but competing with yourself is always an added benefit. I do not believe in Competition but in Domination. Dominate the field you want to excel. Time is the biggest asset you have and utilizing it in an optimized way is the signature of successful. Getting trained before your last semester give you an extra edge over the time as you can decide the technology of your comfort and the major advantage is that while others are planning their future you actually get started working on it.

Java Training Institutes in Mumbai – Top 9 FAQ

Here with, I am publishing the FAQs on Java Training Institutes in Mumbai. According to Google, there are 6,53,000 results shown in less than a minute’s time. Many people search for this to find out the best Java Training Institutes in Mumbai.

1) Why do people search for Java Training Institutes in Mumbai?

The answer is straight and simple. Most people want to be IT industry and learning Java will boost their Job Opportunities. The scope for Java has raised after the raise of Android

Mobile phones as it is used to create Android Apps too.

2) I am a Mumbai based Computer Science Graduate. Do you think, it is good to have Java training in any of the institutes?

Not necessarily. It is not about what graduate you are. It is about what skill set you have or You want to have. If you feel you are not good in Programming even after your graduation,

it is good to have extra training on a programming language like Java from the training institutes in Mumbai.

3) What should I focus more in Java as a Fresher?

For a fresher, it is mandatory that he/she should be very good in basics. If it is Java, OOPs basics are essential. The concepts like Polymorphism, Abstraction, Encapsulation are necessary things to learn.

4) Shall I go for Advanced concepts (J2EE) directly as it has more Job opportunities?

No, not at all. First of all, you should not select your professional course only based on the opportunities. Your skill set should play a vital role in selecting a professional course. There is nothing harm in minding Job opportunities as well along with your talent. But, Job opportunities is just the back seater and Skill set is the driver. To your question, without good knowledge and practical experience in Core Java, it is not advisable to learn J2EE.

                        

5) If I know J2EE too, I can clear more Java Interviews as a fresher. Am I right?

Definitely. In Interviews, at first, they will check your Core Java knowledge. Once they satisfy with the answers you provide, they will move to J2EE part. The organizations know that though you answer for J2EE, it is just the practical exposure and not experience. Thus, being strong in Core Java part is more essential than knowing J2EE for a fresher.

6) Where can I find good Java Training Institutes / Centers in Mumbai?

There are number of good Java Training Institutes in Mumbai. Anna Nagar is the pioneer place for software training institutes in Mumbai. Now, Velachery becomes the hub for Software Training Centers due to its transportation facilities. But, Don’t restrict to Anna Nagar and Velachery. There are good Java training providers every where in the city including Guindy, Chromepet, Tambaram, etc.

7) How much they charge normally monthly for Java Training?

Most of the training providers do not charge monthly. They charge coursewise. And, when it comes to Java Training, there are institutes which even provide the course for 5000. In an average, most of the institutes charge from 10K to 15K. It entirely depends on the facilities they provide to you. In my opinion, one should not check the charges alone. As a trainee, what are all the facilities I am going to get is more important than the fees what I pay.

8) What is about the placements by these training institutes?

Some Training Institutes do provide Placement Assistance to the trainees. Please be careful in this – that, providing training to the pupil is the primary goal of a training institute. If you wish them to provide placement also, Then it is your responsibility to check that with them very clearly. Along with this enquiry, it is highly advisable and good to check their websites, Social Media pages to check if they could afford you placements or not.

9) Shall I rely on their reviews before joining?

Verifying the reviews is a good point before joining. It is important to verify the authenticity of the reviews as well. As there are huge competition among the institutes, we cannot rely anyone blindly. As a customer / student, it is our responsibility to check the Genuineness of the reviews. If possible, try to get Video reviews of the institutes. That could be authentic and reliable source.
