1. What is JIT compiler?
Just-In-Time(JIT) compiler:It is used to improve the performance. JIT compiles parts of the byte code that have similar functionality at the same time, and hence reduces the amount of time needed for compilation.Here the term “compiler” refers to a translator from the instruction set of a Java virtual machine (JVM) to the instruction set of a specific CPU.
2. What is platform?
A platform is basically the hardware or software environment in which a program runs. There are two types of platforms software-based and hardware-based. Java provides software-based platform.
3. What is the main difference between Java platform and other platforms?
The Java platform differs from most other platforms in the sense that it's a software-based platform that runs on top of other hardware-based platforms.It has two components:
- Runtime Environment
- API(Application Programming Interface)
4. What gives Java its 'write once and run anywhere' nature?
The bytecode. Java is compiled to be a byte code which is the intermediate language between source code and machine code. This byte code is not platform specific and hence can be fed to any platform.
5. What is classloader?
The classloader is a subsystem of JVM that is used to load classes and interfaces.There are many types of classloaders e.g. Bootstrap classloader, Extension classloader, System classloader, Plugin classloader etc.

Hi There,
Amaze! I have been looking bing for hours because of this and I also in the end think it is in this article! Maybe I recommend you something helps me all the time?
I have a page in that it show connected system names "device" page, user can click on any system it shows login dialog, on success.
Now If the user click the back button form 'list Page', and once again click back button it navigate to /device page and once again if the user click back button.I expect it should go out of the application stack and it show [initial screen assume google.com]
But, in my case after clicking Complete button page navigate to list view, and user click back button it shows device list, once again if I click back button, page wont navigate stay on the same page and once again I click back button it move to list view and once again i click back button, it moves to device page.
But great job man, do keep posted with the new updates.
Merci Beaucoup,
Sanny
Hi There,
What a brilliant post I have come across and believe me I have been searching out for this similar kind of post for past a week and hardly came across this.
As part of my curriculum, I am implementing a project with the technologies - Angular2, webapi, C#, and bootstrap. In my project, I have developed 3 components and using them as nav tabs and defined routing configuration When the user clicks on each tab the respective tab has radio button selection and upon radio button selection related data is displayed in tabular format. Until this point, I am able to implement successfully.
Now, I want to implement Button click event. A button should be displayed after table view only when the user selects the radio button and I am stuck here implementing button click event.
Can some expertise help me in achieving this?
I look forward to see your next updates.
MuchasGracias,
Franda
