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.
