Declare AND initialize an single-dimensional array of 5 doubles with the name "list". You do not need to set the values of the doubles.

If we had declared but NOT initialized "list", what value would it have?

Write code using a for loop to set each value of "list" to 1. Do NOT use the number 5 directly as the length!

Write code using a for-each loop to print each value of "list" on each line.

Given the code below, what will the values in the array "powers" be?

 public static void main(String [] args) { int [] powers = { 1, 1, 1, 1 }; fillPowers(powers); System.out.println(Arrays.toString(powers)); } public static void fillPowers(int [] powers) { powers[0] = 1; for(int i = 1; i < powers.length; i++) { powers[i] = powers[i-1]*2; } } 

If I want to copy the contents of "list2" into "list1", should I use the code below? If not, why not?

list1 = list2; 

If I call my Java program "TestArgs" on the command line as shown below, what would be the contents of args[2]?

java TestArgs Totoro "Spirited Away" "Howl's Moving Castle" 

Declare and initialize a 2D doubles array of 3 rows and 4 columns named "M". You do not need to set the values in the array.

Given the 2D array "M", write code to store the length of the first row into an int variable "firstLen". Do NOT use the number 4 directly as the length!
