More Rectangle Methods • Write a method that returns the top right corner • Write a method that returns the bottom left corner • Write a method that returns the area of the rectangle • Write a method that returns the length of diagonal of the rectangle. • Write a method that returns the center of the rectangle (intersected point of the 2 diagonals)

00:01 Hello students, here we have to write the program that prompt the user to enter the point x ,y and check whether the point is within the rectangle centered at 0 ,0 with width 10 and height 5.

00:13 So, here width is given 10, so this one is 10, this width and height is given here 5.

00:22 So, width is 10 and height is 5.

00:26 So, for example, if i take the 2 ,2 point, it is inside the rectangle but if i take 6 ,4 it is not in the rectangle because it becomes 5, so this is not inside the rectangle.

00:39 So, this point is outside and this point is inside.

00:45 So, we have to now write the program for this.

00:50 So, we have to write two classes here coordinates .java and test coordinates .java.

00:57 So, first coordinates .java.

01:00 So, here coordinates .java public class coordinates here i am taking x and y which the user will enter so its type is double.

01:10 Public coordinates, so here coordinates constructor which taking the arguments x and y so these are allocated to the class data.

01:21 These values will come from the user.

01:23 Now boolean type is in rectangle or not.

01:27 So, we will first find is in rectangle or not.

01:32 The point are in the rectangle or not.

01:34 So, here double half width we have to do the half because it's on the origin.

01:41 That's why we have to divide the width and divide the height.

01:45 So, these are the double type data and i have taken the new variable half width and half height where it will say store the half of value of the coordinates return math .absolute here i am taking the absolute value that's why i am this value this function is in math library.

02:06 So, i am taking this and so i am checking if absolute value of x is less than or equal to half width and absolute value of y is less than or equal to half width.

02:19 So, it will return this in this case.

02:23 So, this is the way and now public string to string this will return the point x and y.

02:32 So, here now second method after finding that the coordinates are inside or not given coordinates after this test coordinate here i am testing...
