Hi experts!

I have a program the i need to write...

i need to write a program that meets the following requirements:


• Define a class named Point with two data fields, x and y, to represent a point's x and y coordinates. Implement the Comparable interface for comparing the points on x-coordinates and on y-coordinates if x-coordinates are identical.
• Define a class named CompareY that implements Comparator<Point>. Implement the compare method to compare two points on their y-coordinates and on their x-coordinates if y-coordinates are identical.
• Randomly create 100 points and apply the Array.sorts method to display the points in increasing order of their x-coordinates and in increasing order of their y-coordinates, respectively.

it has to have a Minimum of three classes, Array.sorts method, collections, selections and methods...

can anyone help me?

how to write jsp program for grade calculating of a sudent marrk using if else

Code a program to calculate the time in minutes for someone to cut a yard. Input the length and width of the yard in feet. Input the length and width of the house in feet. Subtract the area of the house from the area of the yard to determine the amount of grass to be cut. Using 2 square feet per second as the rate at which you can cut the grass (set this up as a constant), determine how long it will take someone to mow the lawn, in minutes.
The program should print:
Length and width of yard
Length and width of house
Area to be cut in square feet
Time to mow the yard in minutes

Input data: (run three times)
Yard - 1500 X 1600 feet
House - 500 X 700 feet

Yard – 4850 X 6000
House – 1000 X 2000
