How to use the geometric framework in the Java class library
The geometric framework is a powerful and commonly used tool in the Java library to handle various geometric -related operations.These frameworks provide a set of categories and methods to enable us to perform geometric calculations in our applications quickly and simply.Here are some common ways to use some common geometric frameworks.
1. Point class
The Point class represents a point on the two -dimensional plane.We can represent a specific point by creating a Point object, and obtain the coordinates of the point through the getX () and Gety () methods.
Example code:
Point point = new Point(10, 20);
System.out.println ("The coordinates of the point are: (" + point.getx () + "," + point.get () + "));
2. LINE class
The LINE class represents a line segment on the two -dimensional plane.We can represent a specific line segment by creating LINE objects, and obtain the starting point and end point of the line segment through the GetStartpoint () and Getendpoint () methods.
Example code:
Point startPoint = new Point(10, 20);
Point endPoint = new Point(30, 40);
Line line = new Line(startPoint, endPoint);
System.out.println ("The starting point of the" line segment is: (" + line.getStartpoint (). Getx () +", " + line.getStartpoint (). Gety () +") "););););
System.out.println ("The end of the" line segment is: (" + line.Getendpoint (). Getx () +", " + line.Getendpoint (). Gety () +")););););
3. Rectangle class
The RECTANGLE class represents a rectangle on the two -dimensional plane.We can represent a specific rectangle by creating a Rectangle object, and obtain the width and height of the rectangle through the GetWidth () and Getheight () methods.
Example code:
Rectangle rectangle = new Rectangle(10, 20, 50, 30);
System.out.println ("The width of the rectangle is: + RECTANGLE.GetWidth ());
System.out.println ("The height of the rectangle is: + RECTANGLE.Getheight ());
4. Circle class
The Circle class represents a circle on the two -dimensional plane.We can represent a specific circle by creating a Circle object, and obtain the center and radius through the GetCenter () and Getradius () methods.
Example code:
Point center = new Point(50, 50);
Circle circle = new Circle(center, 30);
System.out.println ("The coordinates of the round heart are: (" + circle.getcenter (). Getx () + "," + Circle.getcenter (). Gety () + ")););););
System.out.println ("The radius of the circle is: + Circle.getradius ());
This is just an example of a small number of class and methods in the geometric framework.There are many other geometric classes and methods in the Java library, which can meet various different geometric computing needs.By using these geometric frameworks, we can make more efficient and convenient geometric calculations and simplify our code.
