PLS use basic Java

Canadian phone number has the following format: +1 (NPA) NXX-XXXX Country Area Code Code Prefix Subscriber Area Code=Three digits starting with 2-9 Prefix= Three digits starting with 2-9 Subscriber= Any four digits 0-9 Write a java program, using loops, that asks the user to enter a phone number then if correct print the Area Code, Prefix, and Subscriber numbers. If not correct, print what is wrong. Sample run: Enter a number or -99 to quit: +1 (604) 277-9999 The number is correct with area code: 604, prefix 277, and subscriber 9999 Enter a number or -99 to quit: 1 (104) 277-0123 Country code doesn't start with + and area code doesn't start with a 2-9 number. Enter a number or -99 to quit: 1 (104) 177-7634 Country code doesn't start with + and area code and prefix don't start with a 2-9 number. Enter a number or -99 to quit: +2 (104) 166-9876 Country code is not 1 and area code and prefix don't start with a 2-9 number. Enter a number or -99 to quit: +2 (104) 777-3377 Country code is not 1 b and area code doesn't start with a 2-9 number Enter a number or -99 to quit: +2 (604) 177-2854 Country code is not 1 b and prefix doesn't start with a 2-9 number. Enter a number or -99 to quit: +1 (604) 277-12345 Subscriber number is more than 4 digits Enter a number or -99 to quit: -99 The program is ending

Expert Solution
Step 1

Assuming all the corner test cases covered in screenshot, I am writing the code. For eg. Considering user always inputs country code enclosed in round brackets. I am not using regex as well since, you asked for very simple code so, I will be only using if else conditions for validation. I am also assuming that in 2,3test case there is space instead of +. You can check running all the test cases , In screenshot I have only shown 1,2 and last test case.
