在 Java 中計算兩點之間的距離

package delftstack;

import java.util.Scanner;
public class Distance_Two_Points {
    public static void main(String[] args) {
        Scanner Temp = new Scanner(System.in);

        // declare the variables
        int x1;
        int x2;
        int y1;
        int y2;
        int x;
        int y;
        double Distance_Result;

        // get the input coordinates
        System.out.print("Enter the values of first point coordinates : ");
        x1 = Temp.nextInt();
        y1 = Temp.nextInt();
        System.out.print("Enter the values of second point coordinates : ");
        x2 = Temp.nextInt();
        y2 = Temp.nextInt();

        // Implement pythagorean theorem
        x = x2-x1;
        y = y2-y1;
        Distance_Result = Math.sqrt(x*x + y*y);

        System.out.println("Distance between the two points is : " + Distance_Result);
    }
}

Enter the values of first point coordinates : 12
21
Enter the values of second point coordinates : 13
34
Distance between the two points is : 13.038404810405298
