- Declare a method with three arguments all of the type int. The method should return the greatest of the three arguments, however, if any two or all three are the same, your method should return that valuearrow_forwardQUESTION 10 Multiple Choice: What is the return type of the following method? public static void widget(double a, String b){ ... } String void int double QUESTION 11 Multiple Choice: Which statement is true about the method below? public static String doStuff(int x, double n, boolean b){ ... } String is the return type of this method int x, doublen, and boolean b will cause a syntax error and should be moved to the method body public and static are identifiers for the method O doStuff is a modifier for the method QUESTION 12arrow_forward3) The following method should return true if the int parameter is even and either positive or 0, and false otherwise.Which set of code should you use to replace … so that the method works appropriately?public boolean question3(int x) { … }a) if (x = = 0) return true; else if (x < 0) return false; else return question3(x – 1);b) if (x = = 0) return false; else if (x < 0) return true; else return question3(x – 1);c) if (x = = 0) return true; else if (x < 0) return false; else return question3(x – 2);d) if (x = = 0) return false; else if (x < 0) return true; else return question3(x – 2);e) return(x = = 0);arrow_forward
- Where do I place a return method for finding the area of a square, triangle, and rectangle? Also are the math equations correct for each shape? //PSEUDOCODE //Write a program that demonstrates method overloading by defining and calling methods that return the area //of a triangle //a rectangle //a square private static void area(float a) { System.out.println("The area of the square is " + String.format("%,.2f", Math.pow(a,2)) + " sq units"); } private static void area1 (float a, float b) { System.out.println("The area a of the rectangle is " + String.format("%,.2f", a * b) + " sq units"); } private static void area (float a, float b) { double c = 0.5 * (a * b); System.out.println("The area of the triangle is " + String.format("%,.2f", c) + " sq units"); } public static void main(String[] args) { area(5); area1(05,21); area(05,05); } }arrow_forwardProgram62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.arrow_forwardFree Response Question: 28. Write a method that will return true if a randomly generated number between 1 and 10 is less than or equal to 4. public static boolean FortyPercentOrLess() { }arrow_forward
- A void method may contain a return statement in which form (assume x is int)? O return x; O return 10; return; return (x);arrow_forwardThe windChill method accepts the temperature and wind speed as whole numbers and returns the calculated wind chill as a whole number. Note: temperature is the first parameter and windSpeed is the second parameter. Complete the header for method windChill: public static windChill (arrow_forwardExamine the method header below, then write a call to the method as an example.a personal void ShowValue()arrow_forward
- Find the error in the following method definition:Look at the following method header:public static void showValue(int x)The following code has a call to the showValue method. Find the error.int x = 8;showValue(int x); // Error!arrow_forwardConsider the following methods: public void inchesToCentimeters(double i) { double c = i * 2.54; printInCentimeters(i, c); } public void printInCentimeters(double inches, double centimeters) { System.out.print(inches + "-->" + centimeters); } Assume that the method call inchesToCentimeters(10) appears in a method in the same class. What is printed as a result of the method call? inches -> centimeters 10 -> 25 25.4 -> 10 10 -> 12.54 10.0 -> 25.4arrow_forwardQUESTION 2 A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. QUESTION 3 Use the isPrime method that you wrote in previous question in a program that stores a list of all the prime numbers from 1 through 100 in a file. plz answer these question using javaarrow_forward
