21. Playing with JNI we could call qualities that are printed in most other dialects out-of Coffees. Following was their pros and cons: Advantages: We should use your established collection that was prior to now written in other code. We need to telephone call Screen API function. With regard to performance rates. We wish to phone call API reason for some host product that is within c or c++ out of coffee buyer.
Disadvantages: You cannot state develop once run anywhere. Tough to debug runtime error within the indigenous code. Potential risk of security. You cannot call it out-of Applet.
What is actually JNI ?
23. What is JFC ? Coffees Basis Classes become: Simple AWT step one.1 Access to program Smaller section: that are program elements that don’t subclass an existing AWT interface ability. They don’t really have fun with local screen facets because the available with brand new hidden windowing program. As a result he’s less restrictive than just simple AWT elements. Coffee look and feel Assistance having indigenous feel and look Attributes such as Java2D and you will Drag and Lose
twenty-four. What is actually Difference between AWT and you can Move ? Swing will bring a wealthier selection of parts than simply AWT. He could be 100% Java-established. AWT on top of that was created to the attitude whenever an element otherwise convenience of a component just weren’t offered on a single platform, they wouldn’t be on any program. Due to the peer-based characteristics from AWT, what might work at one to implementation may well not manage some other, as the peer-consolidation might not be because powerful. There are lots of most other positive points to Move over AWT: Move brings both extra components and additional capabilities to AWT-replacement parts Swing components can alter their appearance in accordance with the okcupid Profiel zoeken latest “feel and look” library which is being used. Move portion proceed with the Design-View-Controller (MVC) paradigm, for example also provide a far more versatile UI. Swing will bring “extras” to own elements, such as: Icons into the of numerous elements Attractive limits to own elements Equipment suggestions for elements Move areas are lightweight (faster financial support rigorous than AWT) Swing will bring dependent-in the double buffering Swing provides color debugging support to own when you help make your own elements Swing even offers several drawbacks: It needs Coffees 2 or an alternative Container document Whenever you are not as careful whenever coding, it could be slow than simply AWT (every components is pulled) Swing section that look such as for instance indigenous components might not operate exactly including indigenous section

twenty six. How does bond synchronisation occurs in to the a display screen ? [Concern not very obvious if you ask me ] The JVM uses hair along side checks. A display screen is actually a protector in that they watches more a series regarding code, ensuring that only one bond at a time does brand new password. For each display is actually associated with the an item reference. When a bond gets to the first education when you look at the an effective take off out of password it ought to obtain good lock with the referenced object. This new thread isn’t permitted to carry out the fresh new password until it gets the fresh new lock. If bond makes brand new cut-off, regardless of how they renders the new block, they releases brand new lock to the relevant object.
