java面试笔试题大汇总 ~很全面 java面试笔试题大汇总 第一，谈谈final, finally, finalize的区别。 最常被问到。 第二，Anonymous Inner Class (匿名内部类) 是否可以extends(继承)其它类，是否可以implements(实现)interface(接口)? 第三，Static Nested Class 和 Inner Class的不同，说得越多越好(面试题有的很笼统)。 第四，&和&&的区别。 这个问得很少。 第五，HashMap和Hashtable的区别。 常问。 第六，Collection 和 Collections的区别。 你千万别说一个是单数一个是复数。 第七，什么时候用assert。 API级的技术人员有可能会问这个。 第八，GC是什么? 为什么要有GC? 基础。 第九，String s = new String("xyz") 创建了几个String Object? 第十，Math.round(11.5)等於多少? Math.round(-11.5)等於多少? 第十一，short s1 = 1 s1 = s1 + 1 有什么错? short s1 = 1 s1 += 1 有什么错? 面试题都是很变态的，要做好受虐的准备。 第十二，sleep() 和 wait() 有什么区

As I write this foreword, I am collaborating with four leading user interface (UI) component vendors on a presentation for the 2004 JavaOneSM conference. In our presentation, the vendors will show how they leverage JavaServerTM Faces technology in their products. While developing the presentation, I am learning some things about the work we’ve been doing on JavaServer Faces for the past three years. The vendors have their own set of concerns unique to adapting their product for JavaServer Faces, but they all voice one opinion loud and clear: they are very relieved to finally have a standard for web-based user interfaces.

Text mining tries to solve the crisis of information overload by combining techniques from data mining, machine learning, natural language processing, information retrieval, and knowledge management. In addition to providing an in-depth examination of core text mining and link detection algorithms and operations, this book examines advanced pre-processing techniques, knowledge representation considerations, and visualization approaches. finally, it explores current real-world, mission-critical applications of text mining and link detection in such varied fields as M&A business intelligence, genomics research and counter-terrorism activities.

The program uses fminsearch to obtain the transfer function of a tank’s height. This tank is then controlled using a real PID controller. Controller’s tuning (determination of optimum controller’s parameters: gain and time constants) is achieved using the genetic algorithm toolbox. finally, result are plotted using both matlab commands as well as simulink.

this is a document about radio frequency identification RFID, this was a project ,i have done last year ,actually this technology is a very inpotrtant one due to its relation with newest technologies , like GPS , or the miniturization of integrated circuits ,and that is described in chapter 3 . chapter 1 gives an introduction of the technology RFID , chapter 2 gives a discussion of a library using RFID , and chapter 3 is about the future of RFID , and finally the conclusion .

The target of the assignment is to familiarize the student with MIMO channel modeling. The work is based on L. Schumacher’s MIMO channel model implementation, with added capacity analysis. First the channel model implementation is introduced, and thereafter analysis on MIMO channel with different parameters is done. finally a short report on the results is written.

SiftGPU is an implementation of SIFT [1] for GPU. SiftGPU processes pixels parallely to build Gaussian pyramids and detect DoG Keypoints. Based on GPU list generation, SiftGPU then uses a GPU/CPU mixed method to efficiently build compact keypoint lists. finally keypoints are processed parallely to get their orientations and descriptors.

Improved guaranteed cost control and quantum adaptive control are developed in this study for a quadrotor helicopter with state delay and actuator faults. Improved guaranteed cost control is designed to eliminate disturbance effects and guarantee the robust stability of a quadrotor helicopter with state delay. The inapplicability of guaranteed cost control to the quadrotor linear model is addressed by combining guaranteed cost control with a model reference linear quadratic regulator. In the event of actuator faults, quadrotor tracking performance is maintained through quantum adaptive control. finally, the availability of the proposed scheme is verified through numerical simulation
