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.

Group Project In Java(Airline System) A small airline has just purchased a computer for its new automated system. You have been asked to develop the new system. You are to write an application to assign seats on each flight of the airline’s planes.1. Your application should display the following alternatives: "Please type 1 for Roundtrip" "Please type 2 for One-way"2. Enter passenger’s information (name, gender, phone number,...etc)3. Enter departure and destination airports4. Enter depart and return date(if roundtrip)5. Selection for the seatIf the user types 1, your application should provide inputs for both departure and destination airports and corresponding dates. If the user types 2, your application should only provide inputs for departure airport and depart date. Your application should also display a set of inputs for passenger information.Use a one-dimensional array of primitive type boolean to represent the seating chart of the plane. Initialize all the elements of the…

Problem Statement: (The following problem is based on a problem in a number of Java texts, including the text by Gaddis.) Given a numeric expression in prefix form, develop a Java program to evaluate the expression. The following site provides some explanation on prefix expressions, as well as other forms of numeric expressions: Infix, Prefix and Postfix Expressions (Links to an external site.) Input Data: Repeatedly, enter one prefix expression (as a string) at a time at the keyboard alternatively, you may set up an input data file and get the data from the file Stop the inputting, when the user does not want to enter any additional strings NOTE 1: To simplify matters, assume that only non-negative integers are used the allowed operations are binary addition/subtraction, multiplication, division, and modulus operations Processing: Set up a method (or methods) to evaluate the given expression. Output Data: Echo back the entered input string, along with the result…
