import java.util.Arrays;

public class swap{

public static void main(String []args){

int [] arr = {2,4};

swapValues(arr);

}

public static void swapValues(int[] values){

int temp;

System.out.println(Arrays.toString(values));

temp=values[0];

values[0]=values[1];

values[1] =temp;

System.out.println(Arrays.toString(values));

}

Explanation:

In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.

Assoli18 [71]

Answer:

С The player had 3 bonus round attempts and 7 of them earned extra points.

Explanation:

Given

See attachment for correct code segment

Required

Which of the options is not possible?

From the question, we understand that:

$attempts \to [1,4]$ --- attempt can only assume values 1, 2, 3 and 4

The following "if statement" is repeated three times

IF RANDOM[1,10] <= 7:

success = success + 1

This implies that the maximum value of the success variable is 3

The first printed value is the attempt variable

The second printed value is the success variable.

From the list of given options, (a), (b) and (d) are within the correct range of the two variable.

While (c) is out of range because the value printed for variable success is 7 (and 7 is greater than the expected maximum of 3)
