}
Step by step
Solved in 3 steps
- Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…Value-returning methods must pass parameters. -True or -FalseTrue or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.
- List the name of this method and the name and type of its parameter:public void setCredits(int creditValue){ credits = creditValue;}Assume you have this strcut type struct My Struct{ public int x;} Assume a struct s1 is created from MyStrcut and s1.x is assgined to value 15. We call a method, that takes an arugment of type MyStruct and pass s1 as the argument. This method increments the variables x of its argumemt by the value of 4. After returning from the method, what will be the value of s1.x?JAVA Write a class that calculates add, subtraction, and multiplication. The class should include the following methods: Constructor : initialize all values to 0 getAsk() : Ask users to input two integer numbers. This method calls Distribute() method. Distribute() : Ask users to choose which calculation he/she wants. This method calls a method that can add, subtract, or multiply based on the user's option. CalAdd() : add two numbers CalSub() : subtract two numbers CalProduct() : multiply two numbers toString() : toString method that display result of operation. The program should be designed to test the class developed. Your program might look like the following: public class CalculateNumTesting{ public static void main(String[] args){ CalculateNum calculation = new CalculateNum(); calculation.getAsk(); System.out.println(calculation); } }
- Overriding a method is defined as the ability to override the default method.Method overloading: given the following methods, write down the printed output of the method calls.JAVA HELP please Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. Design a simple class and define a maximum method that finds the maximum of two integer values? Design an application to test that your new method is working properly. Now overload the maximum method to accept three double values and return the maximum of these three values? Finally overload the maximum method again such that it accept four double or four integer values and return the average of these four values? Modify your main( ) application to call and test these new methods. In each case the maximum overloaded methods should return the correct maximum values. Attach you java source codes and a screenshot of the output(s).
- Overloading is achieved when two or more methods in the same class have the same: return type parameter type method name method signatures8. Question 8 Which of the following statements is correct for a method which is overriding the following method: public void add(int a) {…} Pick ONE options the overriding method must return void the overriding method must return int the overriding method can return whatever it likesTrue or False A static method can reference an instance variable.
