Evenness Function

Write a function like so:

public static boolean isEven( int n )

The function should return the value true if n is an even number (evenly divisible by 2) and false otherwise.

Also, write

public static boolean isDivisibleBy3( int n )

The function should return the value true if n is evenly divisible by 3 and false otherwise.

Write a main() that contains a for loop to generate all the numbers from 1 to 20. Use if statements inside the loop to mark the number with a "<" if it's even, with a "=" if it's evenly divisible by 3, and with both if it's divisible by both 2 and 3.

1
2 <
3 =
4 <
5
6 <
6 =
7
8 <
9 =
10 <
11
12 <
12 =
13
14 <
15 =
16 <
17
18 <
18 =
19
20 <

If you're cool, it's possible to make the display like this:

1
2 <
3 =
4 <
5
6 <=
7
8 <
9 =
10 <
11
12 <=
13
14 <
15 =
16 <
17
18 <=
19
20 <
