提供給JAVA入門者,免費下載PPT和源碼 很多網(wǎng)友問我學(xué)習(xí)Java有沒有什么捷徑,我說“無他,唯手熟爾”。但是我卻很愿意將自己學(xué)習(xí)的一些經(jīng)驗寫出來,以便后來者少走彎路,幫助別人是最大的快樂嘛! 要想學(xué)好Java,首先要知道Java的大致分類。我們知道,自從Sun推出Java以來,就力圖使之無所不包,所以Java發(fā)展到現(xiàn)在,按應(yīng)用來分主要分為三大塊:J2SE,J2ME和J2EE,這也就是Sun ONE(Open Net Environment)體系。J2SE就是Java2的標(biāo)準(zhǔn)版,主要用于桌面應(yīng)用軟件的編程;J2ME主要應(yīng)用于嵌入是系統(tǒng)開發(fā),如手機(jī)和PDA的編程;J2EE是Java2的企業(yè)版,主要用于分布式的網(wǎng)絡(luò)程序的開發(fā),如電子商務(wù)網(wǎng)站和ERP系統(tǒng)。J2SE開發(fā)桌面應(yīng)用軟件比起VC,VB,DELPHI這些傳統(tǒng)開發(fā)語言來說,優(yōu)勢好象并不明顯。J2ME對于初學(xué)者來說,好象又有點深奧,而且一般開發(fā)者很難有開發(fā)環(huán)境。所以現(xiàn)在應(yīng)用最廣泛又最好學(xué)的就是J2EE了。J2EE又包括許多組件,如JSP,Servlet,JavaBean,EJB,JDBC,JavaMail等。要學(xué)習(xí)起來可不是一兩天的事。 那么又該如何學(xué)習(xí)J2EE呢?當(dāng)然Java語法得先看一看的,I/O包,Util包,Lang包你都熟悉了嗎?然后再從JSP學(xué)起。如果你學(xué)過HTML,那么事情要好辦的多,如果沒有,那你快去補(bǔ)一補(bǔ)HTML基礎(chǔ)吧。其

小弟撰寫的類神經(jīng)pca對圖片的壓縮與解壓縮,對來源圖片training過後,可使用該張圖像的特性(eigenvalue和eigenvetex)來對別張圖解壓縮,非常有趣的方式,再設(shè)定threashold時注意時值不要過大,因為這牽涉inverse matrex的計算.

This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3. 電視遙控器設(shè)計基於MSP430

This package consists of the executable (UCW), a default script file, this file, and the library files. It is important that the header files end up in a include subdirectory of the directory where UCW is found. If you unzip this file using its path information ( use folder names ) this will automatically happen. You can optionally specify the UnderC directory with the environment variable UC_HOME note that this points to the directory containing ucw.exe. If you do this, then you can copy the executable anywhere and it will still be able to find the header files.

In this paper, a new family of Cassinian wave-guides is proposed, simulating and calculation are finished with CST Microwave Studio that based on Finite Integral Technique (FIT), and some results are given. Electromagnetic field mode type of it is TE, electromagnetic field is stronger near neck region, and some resonance frequencies appear. The new Cassinian curve wave-guides will possess higher power than ones of the rectangular and elliptic wave-guides because the height at the position where maximal electric field occurs is smaller.

選擇排序法的概念簡單,每次從未排序部份選一最小值,插入已排序部份的後端,其時間主要花費於在整個未排序部份尋找最小值,如果能讓搜尋最小值的方式加快,選擇排序法的速率也就可以加快,Heap排序法讓搜尋的路徑由樹根至最後一個樹葉,而不是整個未排序部份,因而稱之為改良的選擇排序法。

說明 除了自身之外,無法被其它整數(shù)整除的數(shù)稱之為質(zhì)數(shù),要求質(zhì)數(shù)很簡單,但如何快速的求出質(zhì)數(shù)則一直是程式設(shè)計人員與數(shù)學(xué)家努力的課題,在這邊介紹一個著名的 Eratosthenes求質(zhì)數(shù)方法 解。 以背包問題為例,我們使用兩個陣列value與item,value表示目前的最佳解所得之總價,item表示最後一個放至背包的水果,假設(shè)有負(fù)重量 1~8的背包8個,並對每個背包求其最佳解。
