WebMay 2, 2015 · May 4, 2016 at 9:48. A one-liner to accept positive and negative indices would be something like this: i >= 0 ? array [i] : array [array.length+i]; You may add it to as a static method to your Utils class and just call that method, like Util.getElementAt (array, i);, instead of array [i]. – Alexander Jank.
WebJun 13, 2016 · Int division in a computer basically is very similar to how you would do long division with paper and pencil to get a quotient and a remainder. The main difference is, the computer does it in base 2 instead of base 10. When you divide with '/', the result is the quotient, and the remainder is thrown away. When you divide with '%', you get the ... WebInteger types stores whole numbers, positive or negative (such as 123 or -456), without decimals. Valid types are byte, short, int and long.
