A year in the modern Gregorian Calendar consists of $365$ days. In reality, the earth takes longer to rotate around the sun.

To account for the difference in time, every $4$ years, a leap year takes place.

A leap year is when a year has $366$ days: an extra day, February $29$th$.$

The requirements for a given year to be a leap year are:

The year must be divisible by $4$

If the year is a century year $(1700,1800,$ etc.$),$ the year must be evenly divisible by $400$

Some example leap years are $1600,1712,$ and $2016($but not $1700$ and $1801).$

This program will again determine whether a year is a leap year, but will use a method to make the determination this time.

Start with the supplied template code, editing the top of program comment to include your FULL NAME.

$(1)$

Fill in the method definition for the isLeapYear$()$ method $($below the main$()$ method in the template$).$

The isLeapYear$()$ method takes a year as a parameter

and returns a boolean set to the correct value for that year $($true or false$).$

There should be no output displayed from the isLeapYear$()$ method

Note that per the Coding Standards: Every method should converge on one return statement.

Therefore, this method should not be implemented with multiple return statements.

$(2)$

Modify the main$()$ method to call the isLeapYear$()$ method

and use the returned value in a decision statement to display the result as:

$1954$ is not a leap year

or

$2016$ is a leap year

NOTE: The last test is a Unit Test, which will test that your isLeapYear$()$ method was defined correctly. JAVA
