reads a Java program and makes a list of all the user-defined identifiers.

Write a program called Guests.java that prompts a user to enter how many guests he will host. Next, reads a series of the names into an array of Strings using Scanner, and then prints back "Welcome" to all of those guests.

Write a program to build a calculator. Instead of a typical calculator which reads in-order expressions and evaluates them, build a calculator that takes in numbers and assigns the operations to yield the highest value expression. The current operations on the calculator only handle pairs of parentheses, and the operators for addition, subtraction, multiplication, and division. The calculator can rearrange the numbers if it helps find the optimal value. For example, the list:4.0 5.0 3.0 2.0 1.0using the calculator should find the optimal expression yielding the maximum value to be:4.0 * 5.0 * 3.0 * (2.0 + 1.0) = 180Input from the keyboard a list of up to 10 floating-point values from-100000.0to100000.0. Output to the screen a single floating-point value rounded to two decimal places representing the highest value expression that the calculator could create by inserting the symbols( ) + - * /into the given expression. Assume at least one number in the list and only the operators listed...

Write a code that generates a random lowercase letter. In java programming. Note: Not a string of letters just one letter is generated every time the program is run. meaning the output should not be something like this: a c t c -that's a random string, it should only be one random letter generated randomly.

Write a FULL Java procedural program for one human player to play a "Higher or Lower" card game. In this game, each card has a value from 1..10 inclusive. There are 4 of each value in the deck, i.e., 40 cards in total. Cards are not replaced in the deck once drawn, i.e., no more than 4 of each value will be drawn. The program starts by asking the player for a target score. The game proceeds in a series of rounds with the program repeatedly drawing and showing a card from the deck to the player one at a time. Each time, it asks the player to enter "h" (higher) or "l" (lower) to guess whether the next card drawn will be higher or lower in value. The player gains a point if they guess correctly. The game continues until the player guesses incorrectly or the target score is reached. When the game ends, it prints either a "You win!" or a "Nice try, you scored ..." message as illustrated below. The image provided shows two examples of the required program behaviour: (bold is keyboard input...

Write a FULL Java procedural program for a simple word guessing game. Below is an example of the required program behaviour. The bold text is user keyboard input. The player is allowed to guess one letter or the whole word incorrectly up to 5 times; each incorrect guess is called a "strike". The program starts by displaying one full stop (’.’) for each character of the secret word. You may assume the word is hardcoded into the game, is in lower case, and is of length greater than one. In each round of the game, the game first checks if the player has reached the maxinum number of strikes; if so, the player loses and the game ends. If not, the game prints an input prompt. The player then guesses either one letter (by entering a single character) or the whole word (by entering multiple characters). If a single letter is guessed correctly, meaning the character occurs in the word, the game reveals the positions of those occurrences in the word and proceeds to the next round. If the whole...
