JNI is an acronym regarding Coffees Native Screen

21. Having fun with JNI we can label properties being printed in other dialects of Coffee. Pursuing the is actually the benefits and drawbacks: Advantages: We want to make use of present collection which had been in earlier times created in other code. We should name Screen API form. In the interests of execution speed. We would like to phone call API intent behind certain server product which is actually c otherwise c++ from java consumer.

Disadvantages: You simply cannot state build once-run everywhere. Tough to debug runtime error from inside the native code. Potential threat to security. You can’t refer to it as of Applet.

23. What is JFC ? step 1 Use of software Little elements: being program section that don’t subclass a preexisting AWT program ability. They don’t play with local user interface issues since the provided with the newest underlying windowing system. Because of this he could be less limiting than just practical AWT parts. Java feel and look Help having local look and feel Attributes like Java2D and you may Drag and Lose

Coffee Foundation Groups tend to be: Fundamental AWT step one

24. What is Difference in AWT and Swing ? Move provides a richer set of elements than AWT. He is one hundred% Java-situated. AWT at exactly the same time was developed to the attitude that when a feature or convenience of a component weren’t offered on a single program, they wouldn’t be on one platform. Due to the fellow-depending character off AWT, what can run you to definitely execution may not work on several other, as fellow-consolidation may not be as the powerful. There are a few most other advantageous assets to Swing over AWT: Move provides each other additional parts and you will added capability to help you AWT-replacement section Move portion can change their looks according to research by the newest „look and feel“ library that’s used. Move components follow the Design-View-Control (MVC) paradigm, which means offer an even more versatile UI. Move brings „extras“ getting components, eg: Icons into the of numerous elements Pretty limitations to have components Device strategies for areas Move areas try smaller (faster money rigorous than just AWT) Swing provides established-when you look at the twice buffering Move will bring painting debugging service getting once you make your individual components Swing is served by a number of cons: It will require Coffee dos otherwise another Jar file When you are much less cautious when programming, it could be slowly than simply AWT (all section is pulled) Swing parts that look such as for example indigenous parts may well not act exactly such as local elements

What exactly is JNI ?

twenty five. Provided notepad/Ie or any other point since the techniques, What takes place for folks who initiate notepad or Ie 3 times? Where step 3 procedure try been or step 3 posts is been ? 3 independent techniques are become.

twenty six. How does thread synchronization occurs to the a display screen ? [Concern not very clear for me ] The brand new JVM uses hair with checks. A monitor is actually a guardian where they observe more a series from code, making certain that only one thread simultaneously performs the newest code. For each display is for the an object source. When a bond gets to the initial education inside a beneficial take Thornton escort service off of code it should obtain a great lock towards the referenced target. The fresh new thread isn’t permitted to carry out the fresh new password up until they receives this new secure. Just after it offers acquired brand new secure, the fresh bond gets in the new take off away from protected password. If the thread makes the newest cut off, in spite of how they makes the fresh stop, they releases the newest secure towards the relevant target.

27. How do you label an enthusiastic Applet playing with a coffees Script mode ? Along these lines: document.appletName.methodCall(. ) Doesn’t work that have Web browser no matter if

twenty-eight. Will there be any level in the HTML in order to publish and download data files ? I’m not aware of HTML tags to simply help myself publish a file, we possibly may certianly need some host front side scripting so you can procedure that. We could certainly have fun with HTML to incorporate a download connect as the follows: code: Click on this link to help you obtain
