Using Java(netbeans), please create the following arrays:

1. myArray, which contains the numbers 1-5
2. stringArray, which contains 5 strings
3. An emptyArray
4. An inventory array
5. lengthArray, which contains 0-10

Once you have done that, please do the following:

1. Print the number “1” from myArray
2. Print the 3^rdelement in the stringArray
3. Append the word “foo” to the emptyArray
4. Add six items to the inventory
5. Print the length of the lengthArray
6. Loop through lengthArray using a for loop, adding 5 to each element

// need an Inventory class to create Inventory array
class Inventory {

    String name;
    double price;

    public Inventory(String name, double price) {
        this.name = name;
        this.price = price;
    }
}

public class ArrayProblem {

    public static void main(String[] args) {

        //myArray, which contains the numbers 1-5
        int[] myArray = {1, 2, 3, 4, 5};

        //stringArray, which contains 5 strings
        String[] stringArray = {"John", "Peter", "Paul", "Jacob", "Issac"};

        //An emptyArray
        String emptyArray[];

        //An inventory array
        Inventory inventory[];

        //lengthArray, which contains 0-10
        int[] lengthArray = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

        // -------------------------------------------------------  //

        //Print the number “1” from myArray
        System.out.println("myArray[0] = " + myArray[0]);

        //Print the 3rdelement in the stringArray
        System.out.println("stringArray[2] = " + stringArray[2]);

        // Append the word “foo” to the emptyArray
        emptyArray = new String[1];
        emptyArray[0] = "foo";


        // Add six items to the inventory
        inventory = new Inventory[6];
        inventory[0] = new Inventory("Apples",12);
        inventory[1] = new Inventory("Oranges",5);
        inventory[2] = new Inventory("Grapes",3);
        inventory[3] = new Inventory("Kiwi",2.99);
        inventory[4] = new Inventory("Apricot",1.99);
        inventory[5] = new Inventory("Banana",5.99);


        // Print the length of the lengthArray
        System.out.println("lengthArray.length = " + lengthArray.length);


        // oop through lengthArray using a for loop, adding 5 to each element
        for(int i=0; i<lengthArray.length;i++){
            lengthArray[i]+=5;
        }
    }
}
