Homework

1. Create Sep16ArrayHomework.java
   1. Create a new int array(6) (“numbers”) and add the following values: -100,2,3,100,-5,14
   2. Create a new int array(20) (“bigCapacityNumbers”) and use for loop to copy all elements from “numbers” to “bigCapacityNumbers”
   3. Add code to count how many negative numbers inside the “numbers” array. Hint: you have to use for loop and if statement.
   4. Study this modulus operator – https://www.khanacademy.org/computing/computer-science/cryptography/modarithmetic/a/what-is-modular-arithmetic
   5. Modulus (%) is an operator that is supposed to give you a reminder of a division. Copy below codes and run it

      1. class ModulusOperator {
             public static void main(String[] args) {
                 int num1, num2, result;
                 num1 = 26;
                 num2 = 15;
                 System.out.println("num1=26; num2=15");
                 result = num1 % num2;
                 System.out.println("The result after modulus operation is : " + result);
             }
         }

   6. After you learn how to use modulus in Java, write a code that will go through each element inside “numbers” and print all odd number inside the list using modulus (%) operator.
