* 简单的读/写文本文件的示例 * 这里包含了三个例子，即 * 1. 将文件读入到内存（这里是StringBuffer）的例子 * 2. 将内容中的文本写到文件 * 3. 将一个文件的内容读出来写入另一个文件中 同时也展示了如果从输入流中读出来内容写入输出流中（仅限文本流） 三个例子可以独立存在，所以根据需要只看其中一个就行了-* A simple read/write a text file that contains the sample* of the three examples here, that is* 1. To file read into memory (in this StringBuffer) examples* 2. Will write the contents of the text file* 3. Will the contents of a document read out to write another paper also demonstrated from the input stream to read out the content written into the output stream (only the text flow) the existence of three examples can be independent, so one need only look at the line a

编写求解几何图形（如直线、三角形，矩型，圆，多边型）的周长、面积的应用程序，要求尽可能多的用到面向对象技术的特点，如继承，多态，封装，抽象类，接口，内部类，包等技术。写出算法。-prepared to solve geometric shapes (such as linear, triangular, rectangular, round, the multilateral type) of the perimeter, the area of application procedures, requirements as much as possible the use of object-oriented technology features, such as inheritance, polymorphism, packaging, abstract category, interface, internal categories, such as packet technology. Write algorithm.

3． 设计一个接口Shape，接口中包含方法：Draw和Resize。定义一些具体类，如：Point、Line、Circle、Rectangle等，每个类都实现接口Shape。Draw方法绘制图形，Resize方法改变图形大小。用Java实现这些接口和类，并用测试类测试它们。 注意：不需要真正绘制图形，如Line的Draw方法只需输出下面文本即可： “直线的起点是（x1,y1,），终点是（x2,y2）”-3. A Shape interface design, interfaces include : Draw and Resize. Some specific type definition, such as : Point, Line, Circle, Rectangle, each category are achieving Shape interface. Draw method of drawing, graphics Resize changed size. Using Java to achieve these interfaces and class, and use tests such testing. Note : no real drawing, such as the Draw Line method, only the following text can be output : "line is the starting point (x1, y1), and the ultimate goal is to (x2, y2)"
