Answer:
The filled in codes are
1) private static int[] arr;
2) int arr[] = new int[size_of_array];
int increment = 100;
for (int i = 0; i < size_of_array; i++) {
arr[i] = increment * i;
}
return arr;
3) for (int i = 0; i < myArray.length; i++) {
System.out.println(myArray[i]);
4) OneDimensionalArrays result = new OneDimensionalArrays();
result.createIntegers(num);
result.printArray(arr);
Step-by-step explanation:
Create a package named one_dimensional_array and write a class that completes the following "OneDimensionalArrays" class. You will complete the class by filling in code wherever you see the comment:
//******* FILL IN CODE *********
import java.util.Scanner;
public class OneDimensionalArrays {
int[] createIntegers(int size_of_array)
{
//******* FILL IN CODE *********
// Your code will create an array of ints as large as specified in size_of_array
// Fill the array in with the values: 0, 100, 200, 300, ....
// Return the array that you just created
}
void printArray(int[] myArray)
{
//******* FILL IN CODE *********
// Print out your array with one number per line. Get the size of the
// array from the "myArray" parameter (no hard coding the size)
}
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter size of array to create: ");
int num = keyboard.nextInt();
//******* FILL IN CODE *********
// Construct an instance of the OneDimensionalArrays class
// Using this object instance, call createIntegers to create
// an array of integers. Don't forget to save the results
// Then call the printArray method to print out the contents
// of your array.
}
}
Completed Code when filled in looks this way below:
import java.util.Scanner;
public class OneDimensionalArrays {
private static int[] arr;
int[] createIntegers(int size_of_array) {
int arr[] = new int[size_of_array];
int increment = 100;
for (int i = 0; i < size_of_array; i++) {
arr[i] = increment * i;
}
return arr;
}
void printArray(int[] myArray) {
for (int i = 0; i < myArray.length; i++) {
System.out.println(myArray[i]);
}
}
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter size of array to create: ");
int num = keyboard.nextInt();
OneDimensionalArrays result = new OneDimensionalArrays();
result.createIntegers(num);
result.printArray(arr);
}
}
