Chapter 6.3, Problem 28STQ
Consider the variable allCents in the method writePositive in Listing 6.14. It holds an amount of money as if it were all cents. So for the amount $12.95, the int variable allCents would be set to 1295. Using an int variable is somewhat limiting. The largest value of type int is 2147483647, meaning that the largest amount the method can handle a $21,474,836.47. That is more than $21 million, a nice large sum, but we often need to consider larger amounts, such as the national budget or even the salary for the CEO of a large company. How can you easily change the definitions of the methods in the class DollarFormat so that they handle larger amounts of money?

Create a class with a method. The method has to decide whether a given year is a leap year or not.
Note- A year is a leap year if:
• It has an extra day i.e. 366 instead of 365.
It occurs in every 4 year e.g. 2008, 2012 are leap years.
For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap
year. In those cases, we need to check whether it is divisible by 400 or not.

In Java, Use the Phone class as a baseline, and write a method isUSA. It should return true if the country code is 1 and false otherwise.
Also expanding the Phone class, write a method that determines the location of an area code. It should return the name of the area code's city.
For example, if cc = 1 and area code = 510 East Bay Area, 650 SF Peninsula, 415 San Francisco, 408 South Bay Area. For this assignment, use literal strings as return values.
Write a method, printNumbers, with an integer parameter of any value that is printed as a string. For example, the number 123 would be printed as "One-Two-Three" and the number 2022 would be printed as "Two-Zero-Two-Two". This method should use the previous method printNumber to print a single digit.
In main, test this method with at least 5 randomly generated numbers.

Make certain to exclude any punctuation marks from your determination (for example, when the word appears atthe end of a sentence or contains an apostrophe). For example, the isogram “Kim’s” should be considered four characterslong, with the apostrophe ignored.
