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 <
