- Create a method that takes a value and tell whether it is null or not.Declared as: boolean isZero (float a)T/F(If false, correct the statement to make it true) - A void method will return an int valueTrue or False: When passing multiple arguments to a method, the order in which the arguments are passed is not important.
- Free 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() { }Value-returning methods must pass parameters. -True or -FalseRetail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.
- A return statement is the same as a print statement. Anything that a method returns will automatically get printed. True FalseObjective: Create a program that invokes static methods and uses static variables. Note: Please see attached pictures. Also please send a screenshot of the code (Java programming language only)The method overloading process can change the method: Select one: O a. header only O b. header and scope Oc. name O d. scope only
- Examine the following method header; then write an example call to the method. private void ShowValue()Code the following: Language : Java Create a method called triangle that will take in three angles and tell you if you have a triangle Create an overloaded version of the triangle method that only takes in one angle and tells you if it could be a triangle create an overloaded version of the triangle method that only takes in two angles. You must check if it's possible for it to be an isosceles triangle. Don't forget to check both angles : example: angle1*2 + angle2 == 180 or angle1 +angle2*2 == 180Prime Numbers A prime number is a number that can be evenly divided by only itself and 1. For example, the number 5 is prime because it can be evenly divided by only 1 and 5. The number 6, however, is not prime because it can be evenly divided by 1, 2, 3, and 6. Write a Boolean method named IsPrime that takes an integer as an argument and returns true if the argument is a prime number or false otherwise. Use the method in an application that lets the user enter a number and then displays a message indicating whether the number is prime.
