CODE:

public class Array-Assignment {

public static void main(String [] args) {

int [] x = new int[3];

int [] y = {3, 5, 9, 2};

x[2] = y[3];

x[0]++;

y[1] += y[2] * y[0];

int [] z = x;

x = y;

x[1] = 4;

}

}

public class Array-Length {

public static void main(String [] args) {

int [] x = new int[4];

int [] y = {};

int [] z = {0};

System.out.println("x has " + x.length + " elements");

System.out.println("y has " + y.length + " elements");

System.out.println("z has " + z.length + " elements");

}

}

1. Understand the code: analysis is needed before you verify the result with computer Draw a representation of what the computer's memory and screen (if relevant) looks like at the end of each of these programs: public clas3 Array-Declarations { public static void main(String[] args) { int [] w; int [] x = null; int [] y = new int [3]; int [] z = {1, 3, 5, 7, -14}; length 2003 length 1 3 5 7 -145 On an exam or quiz, it's fine to leave out the box for the length, since it's usually obvious what the length is. In the examples below, I will leave out the box for the length. But just so you know, this is the full representation of what memory looks like. 1.
