digitIn10sColumnIsEven


public boolean digitIn10sColumnIsEven(int number)

Given an integer, return true if the 2nd-to-last digit is even.
Otherwise return false;

You can extract the digit in the 10s column as follows:
(1) Divide the number by 10 (integer division)
(2) Extract the last digit using MOD 10.
digit = (number / 10) % 10;


digitIn10sColumnIsEven(22) → true
digitIn10sColumnIsEven(141) → true
digitIn10sColumnIsEven(53) → false

...Save, Compile, Run (ctrl-enter)

public boolean digitIn10sColumnIsEven(int number) { }
