What happens when a nextLine() command is added after a command like nextDouble is unknown (). You must refer to the problem as a "keyboard buffer" when explaining it. What additional options do you have to solve this issue?

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "CharCounter" (without the quotation marks) that gets two Strings called inputEntry and inputCharacter from the user at the command line. Allow for the inputEntry String to be one or more words of input. Check that the inputCharacter String has a length of 1 and note these validations: If it doesn't, provide the user with suitable feedback and conclude the program. If the inputCharacter length is valid (i.e., it has a length of 1), use a while loop to check each position in the inputEntry variable and return the number of times the character occurs. For example, if the inputEntry is "test" and the inputCharacter is "e" you would output: "There is 1 occurrence(s) of 'e' in test."

When is the Decorator pattern applicable? When an existing operation of an object is restricted When an existing operation is enhanced When new operations need to be added to an object at runtime. All of these

Write a restaurant log with a GUI that allows a user to enter customer data such as the customer's name, email address, and phone number. It should also allow a user to enter the date and time and daily sales. The program should also record all the input information to a text and read the file to display prior entries on the frame.

Can some pretty please help with this HW problem?

Please help me by suggesting the steps I should take   For this assignment, you will need two sessions open (e.g., a pair of ssh sessions, or a pair of xterms), one for answering the questions, and one for experimenting with different commands to see if they represent the correct answer. When you are satisfied with one of your commands, copy and paste it from your “experimental” window into your “question and answer” window. In either window, create a directory ~/UnixCourse/commandsAsst. Use cd to make that new commandsAsst directory your current working directory (in both of your session windows). For the remainder of the assignment, you should not cd into a different directory. In one window, give the command ~cs252/bin/basicCommandsAsst to start the assignment. This will place some files into the fileAsst directory from the prior assignment. Some of these will be text files (recognizable as such because their names end with “.txt”) and some are data files (named ending in…

What's the difference between bubbling an event and catching it?

What's the difference between bubbling an event and catching it?

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "MinMax" (without the quotation marks) that declares an array of doubles of length 5, and uses methods to populate the array with user input from the command line and to print out the max (highest) and min (lowest) values in the array.

What would be the outcome if the programmer were to substitute the "displayBalance" command with "sac.balance" instead of "sac.getBalance()"? Why? Revise the programme to ensure its continued operation in the context of the aforementioned alterations.
