Answer:
- import java.util.Random;
- import java.util.Arrays;
- public class Main {
-
- public static void main(String[] args) {
- int n = 10;
- int [] myArray = new int[n];
- buildArray(myArray, n);
- System.out.println(Arrays.toString(myArray));
- }
-
- public static void buildArray(int[] arr, int n){
- for(int i=0; i < arr.length; i++){
- Random rand = new Random();
- arr[i] = rand.nextInt(90) +10;
- }
- }
- }
Explanation:
Firstly, create a method buildArray that take two inputs, an array and an array size (Line 12). In the method, use random nextInt method to repeatedly generate a two digit random number within a for loop that will loop over array size number of times (Line 13-15). The expression rand.nextInt(90) + 10 will generate digits between 10 - 99.
In the main program, call the build array method by using an array and array size as input arguments (Line 8). At last, print the array after calling the buildArray method (Line 9).
Answer:
x = 5, the data type is integer( integer data type is for whole numbers)
2. The data type is string
3. The data type is float (float data type is for decimals)

Answer:
def sum_cubes(n):
if n == 1:
return 1
else:
return n * n * n + sum_cubes(n-1)
print(sum_cubes(3))
Explanation:
Create a function called sum_cubes that takes one parameter, n
If n is equal to 1, return 1. Otherwise, calculate the cube of n, and add it to the sum_cubes function with parameter n-1
If we want to calculate the cubes of the first 3 numbers:
sum_cubes(3) = 3*3*3 + sum_cubes(2)
sum_cubes(2) = 2*2*2 + sum_cubes(1)
sum_cubes(1) = 1
If you substitute the values from the bottom, you get 27+8+1 = 36
Theft or vandalism through to natural disasters are physical threats. Non-physical threats target the software and data on the computer systems, Like hackers or just straight up viruses. Also, untrustworthy apps or games can give your computer viruses as well.
