Question

Analyze the following code. public class Test { public static void main(String[] args) { double radius; final double PI= 3.15169; double area = radius * radius * PI; System.out.println("Area is " + area); } }

Answer 1

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.
