(a) design and implement a program that converts a sum of money to a different currency. the amount of money to be converted, and the exchange rate, are entered by the user. the program should have separate methods for: • obtaining the sum of money from the user; • obtaining the exchange rate from the user; • making the conversion; • displaying the result. (b) adapt the above program so that after the result is displayed the user is asked if he or she wishes to convert another sum of money. the program continues in this way until the user chooses to quit. using java

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documentation/point2d.html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
