Question 13
What is abstract method in Java?
Step by step
Solved in 2 steps with 2 images
- Crete a program that implements at least 4 combination of method overriding and overloading. Decide which class to use to properly illustrate your solution.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!Using explicit constructor can avoid type conversions. Group of answer choices True False
- Write the definition line of the method to overload the 'is equal to' operator (==). You do not need to write the whole method. python methodPlan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policyPlease answer in python 1. Class Methods Use your code from Practice 1 above. Implement a print method to display: make=value model=value d) Instantiate two new objects of type Vehicle. vehicle_3 is a Maserati Levante. vehicle_4 is a Porsche 944 e) Call the print method to print the mnake and model of both instances. OUTPUT EXAMPLE: make=Maserati model=Levante make=Porsche model=944 Note: Output must be in 1 line not in 2 line Output right way: (please follow this output) make=Maserati model=Levante make=Porsche model=944 wrong way : make=Maserati model=Levante make=Porsche model=944
- Complete the method in Java. Name of the public class is Assignment1.javaThe Factory method design pattern is useful since it can be used to create new objects of a particular type dynamically. True Falsehello! can you help debug my program? it's in Java! here are the errors I'm getting: line 189: total_weight cannot be resolved or is not a fieldline 93: the type Snake must implement the inherited abstract method Animal.makeNoise()line 139: the method actual_num_animals(int) is undefined for the type Zooline 152: the left-hand side of an assignment must be a variableline 169: syntax error, insert } to complete Blockline 152: syntax error, insert “. class” to complete expressionline 139: syntax error on token “<“, ( expectedline 139: syntax error on token “{“ invalid AssignmentOperatorline 152: i cannot be resolved to a variableline 152: i cannot be resolved to a variableline 154: i cannot be resolved to a variable here is my code: package zoo; public abstract class Animal { private String name; private double weight; private int age; public Animal() { name=""; weight=0; age=0; } public Animal(String name, double weight, int age) { this.name = name; this.weight = weight;…
- Help writing a method that does the followingprivate 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.Given: interface B { int a; void methodA(); } O no problem the method needs to be public O the variable a must be assigned a value O the method needs to have a body D Question 16 0.5 pts Given: interace B { void methodA(); } class C implements B { void methodA(){ } void methodB(){ } } O methodA cannot be overriden methodB should be overriden methodA should be declared as public in class C everything is fine
