4. Consider the following program segment:public class Ch7_PrExercise4{public static void main (String[] args)intnum;double dec;public static int one (int x, int y){public static double two (int x, double a)int first;double z;Write the definition of method one so that it returns the sum ofx and y if x is greater than y; otherwise, it should return x minus 2times y.b. Write the definition of method two as follows:1. Read a number and store it in z.i. Update the value of z by adding the value of a to its previous value.i. Assign the variable first the value returned by method one withthe parameters 6 and 8.iv. Update the value of first by adding the value of x to its previousvalue.v. If the value of z is more than twice the value of first, return z;otherwise, retum 2 times first minus z.c. Write a Java program that tests parts a and b. (Declare additional vari-ables in the method main, if necessary.) 1. Write a value-retuming method, isVowel, that returns the value true if agiven character is a vowel, and otherwise retums false. Also write aprogram to test your method.

Besides main() this program has one method that computes the amount of raise and the new salary for an employee. The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary { public static void main (String[] args) { Declare variables Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the salary without change; otherwise, compute and print new salary and raise amount main() must display the message } } Note:- Please type and execute this java program and also need an output for this java program as soon as possible.

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.
