Analyze the following code: public class Test ( //main function double radius; final double PI= 3.15169; double area = radius radius Pl; System.out.println("Area is"+ area); Select one: a. The program has a compile error because a constant Pl is defined inside a method. O b. The program compiles and runs fine. c. The program has compile errors because the variable radius is not initialized.

What is the solution for this question ( using java language)
Consider the following method: public static void method (int x, int y) { if (x < y) { method (x+1, y); System.out.print (x + " "); } } What will happen as the result of calling method (2,6)? (Select all correct answers) output will be 6 5 4 3 2 Program goes to an infinite loop because of errors in recursive calls 5 recursive calls will be made from method (3,6) to method (7,6) output will be 5 4 3 2 method (6, 6) will be called inside of the recursion 4 recursive calls will be made from method (3,6) to method (6,6) method (5, 6) will be called inside of the recursion
The Java code provides a Class named Function in Function.java that has a static method named f that takes a double argument and returns the value of . It also has a static method named fprime that takes a double argument for x and returns the value of the slope of f(x). The slope of f(x) can be calculated as . Implement this method. public class Function { public static double f(double x) { return Math.pow(x,3) - 3 * x; } public static double fprime(double x) { // your code goes here } }
SUBJECT-COMPUTER PROGRAMING Write the appropriate method headings using the provided method name for the following 1)Given the radius of a circle, print the area of a circle - printArea. * 2)Calculate and return the sum of two decimal numbers - getSum. * 3)Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed. * 4)Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails.

AS PER THE BARTELBY GUIDELINES THERE ARE 3 MULTIPLE CHOICE QUESTIONS. PLEASE ANSWER THEM ALL. 1. 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); }}a. The program has compile errors because the variable radius is not initialized.b. The program has a compile error because a constant PI is defined inside a method.c. The program has no compile errors but will get a runtime error because radius is not initialized.d. The program compiles and runs fine. 2. Analyze the following code.public class Test { public static void main(String[] args) { int n = 2; xMethod(n); System.out.println("n is " + n); } void xMethod(int n) { n++; }}a. The code has a compile error because xMethod does not return a value.b. The code has a compile error because xMethod is not declared static.c. The code prints n is 1.d. The code prints n is 2.e. The code prints…

I cannot get this Java program to run as the solution on the website says. I have 6 errors and was wondering if maybe you can fix them for me. //Class definition class InchesToFeet {//Main method definitionpublic static void main(String[] args);{ //Declare constant variables final int INCHES_IN_FOOT=12; int inchesLeft; //Compute number of feet in given inches feet=inches / INCHES_IN_FOOT; //Display the message System.out.println(inches+"inches is" + feet + "feet and"+inchesLeft+inches);} }
