1. Find out the output of the following code, and explain your answer.

public class Array {

public static void main(String[] args) {

int[] anArray; // declare an array of integers

anArray = new int[10]; // create an array of integers

// assign a value to each array element and print

for (int i = 0; i < anArray.length; i++) {

anArray[i] = i;

System.out.print(anArray[i] + " ");

}

System.out.println();

}

}

2. What is the output of the following code:

class MultidimensionalArray {

public static void main(String[] args) {

// create a 2d array

int[][] a = {

{1, -2, 3},

{-4, -5, 6, 9},

{7},

};

// first for...each loop access the individual array

// inside the 2d array

for (int[] innerArray: a) {

// second for...each loop access each element inside the row

for(int data: innerArray) {

System.out.println(data);

}

}

}

}
