The output of the program: Here the point (2,2) is within the rectangle in terms of horizontal and vertical distances. Here the point (6,4) is not in the rectangle as the horizontal distance is greater than 5.

Analysis of the problem:
There is a rectangle with vertices a,b,c,d(let). The position of the vertices are :
a=(-5,2.5)
b=(-5,-2.5)
c=(5,-2.5)
d=(5,2.5)
The centre of the rectangle is (0,0). Now a point x,y would be given by the user and the program concludes whether the point x,y is within the rectangle or not.
The approach of the java code:
- Take the input of the 2D coordinates from the user.
- Check whether the horizontal distance is between -5 to 5 and the vertical distance is between -2.5 to 2.5.
- If the condition is true print the coordinate within the given rectangle.
- Otherwise print it is not in the rectangle.
import java.util.*;
class Main{
public static void main(String [] args){
Scanner sc=new Scanner(System.in);
// Taking the input of the points from the user
System.out.print("Enter a point with two coordinates: ");
// Declaring the x,y coordinates for the points
double x=sc.nextDouble();
double y=sc.nextDouble();
//printing the position of the point
System.out.print("Point("+x+","+y+") ");
// checking if the given point is within the rectangle or not
if(x>=-5 && x<=5 && y>=-2.5 && y<=2.5)
System.out.print("is in the rectangle");
else
System.out.print("is not in the rectangle");
}
}
The output of the program:
Here the point (2,2) is within the rectangle in terms of horizontal and vertical distances.
Here the point (6,4) is not in the rectangle as the horizontal distance is greater than 5.
