(1) 设计和编写代表矩阵的Matrix类。该类包括矩阵行列数变量int rows和int cols,矩阵数据数组Double data[][],构造方法Matrix()、Matrix(int rows,int cols)、Matrix(int rows,int cols,Double data[][]),获取某元素值的方法getData(int row,int col),设置某元素值的方法setData(int row,int col,Double value),计算两个矩阵的乘积的方法multiply(Matrix m)以及toString()等内容。

(1) 实现一个Point类,该类包含表示坐标的两个int型变量x、y,构造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法,计算两点间距离的Double distance(Point)方法。其中计算平方根用Math.sqrt()方法。 (2) 实现一个Circle类,该类包含表示圆心的Point型变量center,表示半径的int radius变量,以及构造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r),返回周长和面积的int perimeter()、Double area()方法,返回两个圆是否为同一个圆(返回0)、同心圆(返回1)、相交的圆(返回2)、分离的圆(返回3)、包含的圆(返回4)等关系的int relation(Circle c)等方法。PI值可以用Math.PI常量。 (3) 实现测试上述两个类的ClassTest类。该类在main方法中分别创建若干个Point对象和Circle对象,并调用相关方法,输出方法的返回值,验证其正确性。 (4) 将Point类、Circle类和主类的包名分别调整为p1、p2、p3,并重新运行,验证是否运行正确。

This application includes a demo server and client program. You could write your own server launcher and client application by using the SimpleScreenCaptureServer class and the SimpleRemoteScreenCaptureClient class. Usage: 1. Type the following command to launch the server program. java -jar SimpleCaptureScreenServerDemo.jar portnumber 2. Type the following command to launch the client program. It s a swing-based UI. java -jar RemoteScreenCaptureClientUI.jar 3. Select Run/Connect menu. Input your server address and port number. You could just Double-click on the RemoteScreenCaptureClientUI.jar to launch the client program if you are using Windows. This program is written just for fun. :lol: :lol: :lol:

dwr.xml说明文档。配置文件init部分声明那些用于建立远程bean和在方法调用中转换bean的类.这部分是可选择性配置的,多数情况下可以不必使用它,如果你想定义一个新的creator或者converter那么就必须在部分中声明,but do Double check on the ones that are currently available first.

DDR SDRAM控制器的VHDL源代码,含详细设计文档。 The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS), and Digital Frequency Synthesis (DFS) functions. This application note describes a controller design for a 16-bit DDR SDRAM. The application note and reference design are enhanced versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz, 16-bit data changes at both clock edges. The reference design is fully synthesizable and achieves 133 MHz performance with automatic place and route tools.
