How do i
1.) Create a String array called Lester that has 76 Strings

2.) Create a double array called sue that holds 30 numbers, which are all 3.2

3.) Create an int array called jimmy that holds 12 ints and set them through the numbers 1 through 12, then sum them.

(sorry for all the questions, but i'm really new to this and these are practice exam questions)

Code:

```public class ArrayPractice {     public static void main(String[] args) {         // Create a String array called Lester that has 76 Strings         String[] Lester = new String[76];         // All elements of this array are null.         System.out.println("Lester[0] = " + Lester[0]);         // Initialize the firs element.         Lester[0] = "hello world";         System.out.println("Lester[0] = " + Lester[0]);         // Create a double array called sue that holds 30 numbers,         // which are all 3.2         double[] sue = new double[30];         // All elements are initialized to default zero value.         System.out.println("sue[0] = " + sue[0]);         // Initialize to requested initial value.         for(int j = 0; j < sue.length; j++)             sue[j] = 3.2;         System.out.println("sue[12] = " + sue[12]);         // Create an int array called jimmy that holds 12 ints         // and set them through the numbers 1 through 12, then sum them.         int[] jimmy = new int[12];         for(int j = 0; j < jimmy.length; j++)             jimmy[j] = j+1;         int total = 0;         for(int j = 0; j < jimmy.length; j++)             total += jimmy[j];         System.out.println("total = " + total);     } }```
