Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

#Array question.
Design and implement a class called Car that contains instance data that represents the company, price, model, and year of the car. Define the Car constructor to initialize these values. Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car. Create a driver class called CarTest, whose main method instantiates array of Car objects and write the following methods: 1) Method “printInfo” that receives an array of cars and returns all information about all cars. 2) A Method called getTopByCompany that receives an array of Cars and then returns an array of cars containing the cars that have the highest price compared with cars from the same company.
java code: Create a class Car and perform the following: - Declare public instance variables (name, model, color) as (String, int, and String) respectively. - Define set() method to set a car's name, model, and color. - Define show() method to print out the car's name, model, and color. In the main method: - Declare an array of the defined class Car with length 5. - Create three objects from Car and add them into the array. - Set the objects' values (name, model, color) using set method. - Print out the object's values (name, model, color) using show method
True or false? When an array is passed to a method, a new array is created and passed to the method
In C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.
