我需要这个ASAP的答案。所以我在这个工作正常的一切我只需要在运行应用程序时显示我的x1,y1,x2,y2作为有序对。这就是我到目前为止所拥有的:
import java.util.Scanner; //class used for user input
public class PointSlope
{
public static void main( String[] args )
{
// declare variables
double x1;
double y1;
double x2;
double y2;
double slope;
double distance;
Scanner reader = new Scanner (System.in); // set up scanner
// to read user inputs
//store values in variables
System.out.print ( "Enter x1" );
x1 = reader.nextDouble();
System.out.print ( "Enter y1" );
y1 = reader.nextDouble();
System.out.print ( "Enter x2" );
x2 = reader.nextDouble();
System.out.print ( "Enter y2" );
y2 = reader.nextDouble();
//calculate slope
slope=(y2-y1)/(x2-x1);
//calculate distance
distance = Math.sqrt ((x1-x2) * (x1-x2) + (y1-y2) * (y1-y2));
//display result
System.out.println ( "The distance between the 2 points is," + distance +
",units" );
System.out.println
( "The slope of 2 points is," + slope +
",units" ) ;
}// end of class
} // end of class
答案 0 :(得分:0)
你在谈论这样的事吗?
System.out.println
("("+x1+","+y1+")" );
和
System.out.println
("("+x2+","+y2+")" );
显示为(x,y)?
