Learn Core Java 2012-04-21T19:24:28+00:00

Online Tutorial for Java beginners to learn basic concepts of Core Java. I have divided this tutorial into three sections. First you will learn the fundamentals of Core Java (Class ,Interface etc.) . In the next section Learn By Example you will find many examples for different Core Java modules with running source code. The third part Cheatsheet will help you quickly revise what you learnt in the first two sections.

    • Chapter 1 : Getting Started with Java

      Introductory Chapter for complete beginner of Java. You will learn to start working in Java by installing and running and test java application.

    • Chapter 2 : JDK vs JRE vs JVM

      Here you will learn about 3 main things of Java. And difference between those(JDK, JRE and JVM).

    • Chapter 3 : Class & Object

      In Object Oriented programming Class is the most fundamental thing. In this chapter you will get to know about Classes and Their Objects.

    • Chapter 4 : Constructor

      In order to create Object from a class definition you will require constructor. How to initialize different variable or how to invoke constructor will be learned here.

    • Chapter 5 : Java Variables

      Variables are one of two things which in combination create class, most important part of Java. You will learn about different type of Variables and how they can be used or accessed.

    • Chapter 6 : Hello JBT

      Write first Hello JBT application and understand different part of Application. In next chapter we will develop same application but with help of Eclipse.

    • Chapter 7 : Hello JBT in Eclipse

      Here you will learn to write same Hello JBT Application but with help of Eclipse..

    • Chapter 8 : Access Modifier

      This is how you define access levels for different thing in java. Be it Class / Variables / Method. Who and how it can be accessed from different part of Java world.

    • Chapter 9 : Non Access Modifier

      Java Provided some modifier which doesnt control accessibility but can change the behaviour of particular CLASS / Method / Variable. Theses are called Non Access Modifier. In this chapter you will learn about the same.

    • Chapter 10 : Java Operators

      You will learn about Operators used in Java. What is precedence and associativity of every Operator.

Java Inheritance defines an is-a relationship between a superclass and its subclasses. This means that an object of a subclass can be used wherever an object of the superclass can be used. Read more
A String Builder is like a String, but can be modified. String has drawback that once created it can not be modified. To overcome that problem String Buffer and String builder can be used.

    package ka use kis work ke liye kiya jata hai ?

    • admin September 26, 2013 at 4:26 am - Reply

      Hi Gaurav,

      Package is used for organizing classes. This is not something which is enforced by JVM or Java. But it is suggested to have classes defined in proper package coz in that case you can have unique namespace for different classes(even if class name is same.)

      e.g.
      Suppose you and your colleague is working on different modules(Sales and HR ) of the same project and you both are unware of the class name created by other. In the end you might face a situation where both of you have created class with same name(Department). This will create problem. To avoid this problem you both can use package. You can create class in your specific package(com.sales & com.hr). In this way you will avoid conflict of class name. Coz even if class name is same namespace will be unique.

      com.sales.department
      com.hr.department

      hope now you understand the use of package.

    hello sir.. i have to make a project on core java..would u plz suggest me some topics

    • Vivekanand Gautam October 14, 2013 at 5:16 pm - Reply

      Hi Ayushi,

      I don’t know what is the purpose of creating this project. But i have one project in my mind because of requirement. So i ll tell you. Try to build it and if successful let me know i might use it.

      We have team of developer where Team Lead assign a work to every one on everyday or weekly basis. and every one in the team has to report to team leader. And leader will analyses in the end what different resources has done in last week or month and generate the report accordingly which will be used in Audit purpose.

      So you will have a web application. It will have two User roles.
      1- Team Lead
      2- Developer

      Roles of Developer
      1- Can view the assigned work by team lead.
      2- Can update the work sheet
      3- Can close the work assigned which in return go back to team lead pool

      Roles assigned to TL role
      1- Can create work
      2- Can assign work created to different user(Developer)
      3- Provide the deadline for different work.
      4- Can generate the report of all work done by developer.

      System functionality.
      1- Once there is any work assigned to any developer mail should be delivered to developer.
      2- When deadline is about to read notification should also reach.
      3- Once developer mark and work as completed. Work should go into TL pool.
      4- Report should be generate in the form of DOC/ Excel

      It is the requirement below the technology stack that you can use
      1- Spring 3.1
      2- Hibernate (Data Persistence)
      3- Spring Security (Role related assignment)
      4- Apache POI (Report Generation)

      I think now i have given you enough information. If you like you can create it. If successful let me know i will glad to add it in my website.

      If you require any more input you can contact me.

      Thanks

      Hi Vivek,

      As you can see i have different topics for different section in Java. You can start learning Java by following Java article sequentially. I do not have any idea of C++ language. So i would not be able to help you in this regard.

      I would suggest you to first buy a good book for the same. Or if you want more clarity then you can refer original document of Java.

      Thanks

      Hi Chandra,

      Thanks for your nice comment. If you know the basics then you should not have any problem with writting code. If you want to start coding then you should start with very basics ofcore java like prinitng any value on console. I would suggest you to download Eclipse IDE first.

      I have written different article on how to create Java Project in Eclipse. Once created you can start creating Classes and start playing with same. You can have different assignment available which you can try to solve on your own. Keep in mind that there is no hard and fast rule to learn Java. Only practice can make you perfect.
      While writting code you have specific question you can ask me personally.

      I have a paid service where i use to check the assignment and help learner write code. If you are willing to pay for this let me know.

      Thanks

    • J Singh May 27, 2016 at 3:30 am - Reply

      Java is a language which are divided in 3 different modules for 3 different purpose. J2SE (Core functionality), J2EE(used for Web Application) & J2ME(Used for Mobile platform development). In normal terms J2SE is known as Core java while J2EE is known as Advance Java.

      • Chris June 11, 2016 at 3:50 pm - Reply

        Hello, do you have a tutorial on J2EE? Please reply. Thanks!

        • J Singh June 12, 2016 at 5:35 am - Reply

          Currently we don’t have any J2EE Specifc course. But we do have a JSP section where we have article based on JSP.

    • J Singh May 29, 2016 at 5:46 am - Reply

      Hi Risabh,
      I think you should take help for primary java information from java teacher. It will be very difficult for you to gain basic info online. once you have that you can go through any java course on your own.
