Expert Solution & Answer
Chapter 8.1, Problem 1STQ
Explanation of Solution
Differences between method overloading and overriding:
| Overloading a method | Overriding a method |
| Methods have the same name with different parameters. | Methods have the same name with same parameters of superclass in the subclass. |
| Reusability can be achieved. | No reusability. |
| It blocks the inheritance from super class... |

- Long method or long method is a term for a method that has too many lines. In general, methods that have more than ten lines of code indicate the possibility of code that is too long, so it needs further analysis whether it needs to be broken down into several methods. Creating a method is considered more difficult than adding a few lines of code to an existing method. Especially if only a few lines of code are added. But this is the main cause of bloating a method when another line is added later on. Adding comments in a method to clarify the use of variables, logic, or other lines in a method can also be an indication that lines that should be described separately should be declared in a separate method. A good method has a name that describes the usefulness of the method itself, so the use of comments inside the method should be avoided. Mention some ways that can be done to improve the condition of the method that is too long!arrow_forwardFastarrow_forwardIn python, a method header looks very much like a function header, but a method always has at least one parameter in the first position. What is the name of this parameter?arrow_forward

- What is method overloading? Is it permissible to define two methods that have the same name but different parameter types? Is it permissible to define two methods in a class that have identical method names and parameter lists, but different return value types or different modifiers?arrow_forwardDescribe the differences between method overload and method override.arrow_forwardWhat exactly is method overloading? Is it OK to declare two methods with the same name but distinct argument types? Is it legal to declare two methods in a class with similar method names and argument lists but distinct return value types or modifiers?arrow_forward
- Each method parameter has to have its function clarified. There is a distinction between a parameter and an argument.arrow_forwardAll needed parameters must be passed in during method call.arrow_forwardMethod Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.arrow_forward
