Write a simple program in Java that will generate a well-formatted addition table. Prompt the user to enter a lower bound and an upper bound for the table. Then print the table with row headers, column headers, and a “+” in the upper left corner. Allow 6 spaces for printing the numeric value
Let's finish working on our booking system. The last part for our booking system will be to manage multiple flights. To do this, we'll modify our program's command list. The command "create [id] [cap]" will try to create a new empty flight with ID [id] and capacity [cap]. The command "delete [id]" will try to remove the flight with ID [id]. The command "add [id] [n]" will try to add n reservations to the flight with ID [id]. The command "cancel [id] [n]" will try to cancel n reservations from the flight with ID [id]. If an operation fails for any reason, the program will issue the message "Cannot perform this operation". You can add a more helpful message to identify why the operation failed. The command "quit" will stop the execution of the program. For the sake of simplicty, let's limit the maximum number of handled flights to ten. Use the code from your previous exercise as a starting point. Note that we need to add an access method to the flight id field. PLS ANSWER…
Consider the following scenario: you are asked to create a Java class MetaDisplay that contains a static void printTable(String r) method. The method takes a relation name r as input, executes the query "select * from r," and prints the result out in tabular format with the attribute names displayed in the table's header; the attribute names are displayed in the table's header. What JDBC method(s) can you use to get the information you require? t?
java program For this question, the server contains the id, name and cgpa of some Students in a file. The client will request the server for specific data, which the server will provide to the client. Server: The server contains the data of some Students. For each student, the server contains id, name and cgpa data in a file. Here's an example of the file: data.txt101 Saif 3.52201 Hasan 3.81.... Create a similar file in you server side. The file should have at least 8 students. The client will request the server to provide the details (id, name, cgpa) of the Nth highest cgpa student in the file. If N's value is 1, the server will return the details of the student with the highest cgpa. if N's value is 3, the server will return the details of the student with the third highest cgpa. If N's value is incorrect, the server returns to the client: "Invalid request". Client: The client sends the server the value of N, which is an integer number. The client takes input the value of N…
implement a database about people, they could be made up, but you want to include a sizable number, maybe 10-20. The data that you store for each person must include a name and at least one additional piece of information, such as a birthday. You can assume that the names are unique. The database should enable you to enter, remove, modify, or search this data. You also should be able to save the data in a file for use later. Define a class Person to represent a person and another one to represent the database. A dictionary should be a data member of the database class, with Person objects as search keys for this dictionary. Write a program that tests and demonstrates your database.
Every interface worth its salt must provide access to a full suite of functions. What abilities do you need to have? Is it planned to use a single method across the board? Document your claims by citing appropriate earlier research.
I have a program that asks for queries. It is based on a CSV file with three columns for a person's name, city, and height. The print statement for City_list gives it a blank. The problem I'm running into is that if I insert a city that isn't in the CSV file, it ends and doesn't transition to other cities. When I do put in the city that is in the list, it prints out the indexes from the file. How can this be revised to ignore off-list cities and work with in-list cities?
