- Examine the following method header; then write an example call to the method. private void ResetValue(ref int value)1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…Examine the method header below, then write a call to the method as an example.a personal void ValueReset (ref int value)
- 3. Answer the following: a) Write the signature for a method named calculate that has 2 parameters, all of type double and returns a double value. b) Write the method header for “info” method that has two parameters, both of type int, and returns an integer value. c) Identify the errors in the following code: public classDemo; { int Fruit=”Apple”; private Fruit (String s) { Apple=s; } Show void( ) { Return Fruit; } }1) Through BlueJ, write if the current number of shoppers is greater than or equal to the number leaving then the number of shoppers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of shoppers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the message. 2) The class must define a method called leaving that takes a single integer parameter. This represents the number of shoppers leaving the club at a particular point. You may assume that the parameter's value will always be greater than zero and you do not have to check for that. If the current number of clubbers is greater than or equal to the number leaving then the number of clubbers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of clubbers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the error message. 3)…Local variables are defined in the method and scope of the variables that exist inside the method itself True False
- The value returned from a method must be different from the return type specified in the method header. True or False?If a method does not have a return statement, then Group of answer choices it will produce a syntax error when compiled it must be a void method it can not be called from outside the class that defined the method it must be defined to be a public method it must be an int, double, float or String methodJava code Write the header for a public method named doStuff that has no parameters and no return value. Remember to include the opening brace for the method. Assume that the method will be in the main class and called directly by the main method.
- Write a class called Ave method that contains a main method and method called threeAve( method name) that computes the average of three numbers. A method must be used. Please refer to the pic and show your source code and console.True or False: The value of a local variable is retained between method calls.Question 2 has bigger options otherwise according to your policy they are 3 questions at a time. 1.) The signature of a method consists of ____________. a. method name b. parameter list c. return type d. None of the above 2.) You should fill in the blank in the following code with ______________. public class Test { public static void main(String[] args) { System.out.print("The grade is "); printGrade(78.5); System.out.print("The grade is "); printGrade(59.5); } public static void __________ (double score) { if (score >= 90.0) { System.out.println('A'); } else if (score >= 80.0) { System.out.println('B'); } else if (score >= 70.0) { System.out.println('C'); } else if (score >= 60.0) { System.out.println('D'); } else { System.out.println('F'); } } } a. int b. printGrade c. printMe d. double e. void 3.)
