How do i

[jpnym15]

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);
    }
}
