Question

jump to level 1
four integers are read from input into four variables, num1 to num4. declare an array of integers named usernumbers of size 4. then, initialize the elements of usernumbers with num1 to num4, in reverse order.
ex: if the input is 4 6 75 34, then the output is:
array contents: 34 75 6 4
3 public class usertracker {
4 public static void main(string args) {
5 scanner scnr = new scanner(system.in);
6 int num1;
7 int num2;
8 int num3;
9 int num4;
10 int i;
11
12 num1 = scnr.nextint();
13 num2 = scnr.nextint();
14 num3 = scnr.nextint();
15 num4 = scnr.nextint();

Explanation:

Step1: Declare the array

int[] userNumbers = new int[4];

Step2: Initialize the array in reverse order

userNumbers[0] = num4;
userNumbers[1] = num3;
userNumbers[2] = num2;
userNumbers[3] = num1;

Step3: Print the array

System.out.print("Array contents: ");
for (int i = 0; i < userNumbers.length; i++) {
    System.out.print(userNumbers[i] + " ");
}

Answer:

int[] userNumbers = new int[4];
userNumbers[0] = num4;
userNumbers[1] = num3;
userNumbers[2] = num2;
userNumbers[3] = num1;
System.out.print("Array contents: ");
for (int i = 0; i < userNumbers.length; i++) {
    System.out.print(userNumbers[i] + " ");
}
