Students have asked these similar questions
private float c;
private void method2(double y) {
c = y;
}
in another class we created an object of the first class then within in it :
tester.method2 (10.0f);
are there any errors ? how many errors if there are any and with explanation please.

Assignment:
In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. In this lab you will write a program to decode a message that has been encrypted.
Detailed specifications:
Define three classes. Each one should be in a separate file. You can choose to define the class and its functions inline, all in a header file, or have a .h and .cpp file for each class.
Abstract base class with the following:
A variable to hold an encrypted message. This variable should be a string which is initialized in the constructor.
A status variable that will tell whether the message was loaded successfully.
A constructor that receives one parameter: a string variable with a file name and uploads its content to the string variable that is supposed to store it.
A pure virtual function called decode. This function will be defined in derived classes.
A function that prints the message on the…
When a void method is executing, what happens when the end of the method is reached?

- 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).arrow_forwardIf we do not override the toString method in a class, the toString method for the Object is called.

The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) https://fog.ccsf.edu/~mluttrel/cs110b/NumberGuesser.h In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the…arrow_forward
