（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。

an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic Relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.

In the previous article, we presented an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic Relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.

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 .

data are often used interchangeably, they are actually very different. Data is a set of unrelated information, and as such is of no use until it is properly evaluated. Upon evaluation, once there is some significant Relation between data, and they show some relevance, then they are converted into information. Now this same data can be used for different purposes. Thus, till the data convey some information, t

Do you have a mobile phone? We think you probably do, one way or another. We would also guess that you might use it for many diff erent things in the course of your everyday life—as a telephone certainly, but also as an address book, as a clock or watch, as a camera, or now as a connection to your computer, email and the internet. Th ere will be a range of people you use it to contact (or not), and various strategies you use to take calls—or send texts, or take photos, or receive emails, or search online (or not, in diff erent situations). Th ere are also likely to be a range of social Relation- ships in your life that your mobile phone helps to maintain—or disrupts, or inter- venes in, or makes possible, or complicates, or just plain helps to handle.
