Answer:
The output of the given code as follows:
Output:
Area is: 12.60676
Explanation:
In the given code some information is missing so, the correct code to this question can be described as follows:
Program:
public class Test //defining class
{
public static void main(String[] args)//defining the main method
{
double radius= 2; //defining double variable radius
final double PI= 3.15169; //defining double variable PI
double area = radius * radius * PI; //defining double variable area that calculates values
System.out.println("Area is: " + area); //print values
}
}
Explanation:
- In the given java code a class "Test" is defined, in which a double variable "radius" is defined, which holds a value, that is 2.
- In the next step, a double constant variable, that is PI is defined, that holds a value, that is "3.15169".
- Then another double variable area is defined, that calculates the area value, and prints its value.

Please see below
Explanation:
Yes, there indeed is ethical justification for hacking certain computer systems. Since computer scientists are required to keep the system secure from external threats, so they make use of it when testing the network for potential loopholes that could make it vulnerable. It is beneficial in that it can help manifest the weaknesses present in the system, which can then be corrected for.
You only put a numerical expression in numbers if it is over 100, it the calculation correctly.

INCOMPLETE QUESTION
Consider array items, which contains the values 0, 2, 4, 6 and 8. If method changeArray is called with the method call changeArray(items, items[2]), what values are stored in items after the method has finished executing?
public static void changeArray(int[] passedArray, int value)
{
passedArray[value] = 12;
value = 5;
}
A. 0, 2, 5, 6, 12.
B. 0, 2, 12, 6, 8.
C. 0, 2, 4, 6, 5.
D. 0, 2, 4, 6, 12.
Answer:
D. 0, 2, 4, 6, 12
Explanation:
The initial values for the array was 0,2,4,6,8. The method changeArray ( ) when called changes the the the value of the element at the ith index position to 12. so the final elements in the array will be 0,2,4,6,12
