Explanation of Solution

Allocating an array

In java, an array is created with the keyword new that is used for allocating memory.

Hence allocating an array consists of two steps that is to declare a variable of the desired array type and to allocate the memory that will hold the array using new keyword and assigning it to the array variable.

In java, all arrays are dynamically allocated.

The code for allocating an array of ten integers is
// Declaring an array

int[] nums = new int[10];

b.

Explanation of Solution

Declaring initial element of the array

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

An integer variable can be used as the index of the array.

Hence here 0 is the index of the array.

The code for putting 17 as the initial element of the array is
// Declaring initial element

nums[0] = 17;

c.

Explanation of Solution

Declaring last element of array

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

An integer variable can be used as the index of the array.

Hence here 9 is the last element of the array.

The code for putting 29 as the last element of the array is
// Declaring last element

nums[9] = 29;

d.

Explanation of Solution

Filling remaining elements with -1

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

The for loop is executed for filling the remaining elements with -1.

The code for filling the remaining elements with -1 is
// Execute for loop

for (int i = 1; i < 9; i++)

{

nums[i] = -1;

}

e.

Explanation of Solution

Adding 1 to each element of array

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

The for loop is executed for adding 1 to each element of array.

The code for adding 1 to each element of array is
// Execute for loop

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

{

nums[i]++;

}

f.

Explanation of Solution

Printing all elements of array one per line

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

The for loop is executed for printing all elements of array one per line.

The code for printing all elements of array one per line is
// Execute for loop

for (int num : nums)

{

System.out.println(num);

}

g.

Explanation of Solution

Printing all elements of array in a single line

In java, an array is created with the keyword new that is used for allocating memory.

In java, all arrays are dynamically allocated.

Here if condition is executed inside the for loop for printing all elements of array in a single line.

The code for printing all elements of array in a single line is
// Execute for loop

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

{

// Execute if condition

if (i < nums.length - 1)

// Print the statement

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

else

// Print the statement

System.out.println(nums[i]);
