用于简单的图形的程序

import java.util.Scanner;

public class beeline extends graph {
	beeline() {
		System.out.println("Please input offset about x & y:");
		Scanner in1 = new Scanner(System.in);
		Scanner in2 = new Scanner(System.in);
		Scanner in3 = new Scanner(System.in);
		Scanner in4 = new Scanner(System.in);
		double x, y, x1, y1;
		x = in1.nextDouble();
		y = in2.nextDouble();
		x1 = in3.nextDouble();
		y1 = in4.nextDouble();
		System.out.println("construct completed");
		System.out.println("This beeline info is:");
		System.out.println("本程序中直线的形心为给出的两点的中点。");
		this.x0 = 0.5 * (x + x1);
		this.y0 = 0.5 * (y + y1);
		System.out.println("Area is:0");
		System.out.println("Girth is:0");
