Write a program that does two string functions: capitalize the first word of a phrase, and reverse the letters of words in odd positions within the phrase. For this program it is acceptable to let punctuation be part of the word. Write a capitalizeWords() and a reverseOddWords() method and call them in a test program. Make certain to properly handle empty phrases, phrases with one and two words, and phrases with greater than two words.
For example, if the original phrase were:
Learning Java is fun! Java is powerful and easy to use
The capitalized version would be:
Learning Java Is Fun! Java Is Powerful And Easy To Use
And with reversed odd words would be:
gninraeL Java sI Fun! avaJ Is lufrewoP And ysaE To esU
Write a program that reads HAND_SIZE cards from the user, then analyzes the cards and prints out the type of poker hand that they represent. (HAND_SIZE will be a global constant, typically 5, but your program must still work if it is set to something other than 5.)
Poker hands are categorized according to the following hand-types: Straight flush, four of a kind, full house, straight, flush, three of a kind, two pairs, pair, high card.
To simplify the program we will ignore card suits, and face cards. The values that the user inputs will be integer values from LOWEST_NUM to HIGHEST_NUM. (These will be global constants. We'll use LOWEST_NUM = 2 and HIGHEST_NUM = 9, but your program must work if these are set to something different.) When your program runs it should start by collecting HAND_SIZE integer values from the user and placing the integers into an array that has HAND_SIZE elements. It might look like this:
Enter 5 numeric cards, no face cards. Use 2 - 9.
Card 1: 8
Card 2: 7

- Write a program in Java that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: MichaeJ_1 Ex: If the input is: Nicole Smith 2024 the output is: Your login name: NicoleS_4arrow_forwardWrite a Java program that would resemble a payroll system. An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window. Design your own input/output windows.

Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly. If…arrow_forward

So, the in- sertion method has this specification: public void insert(String entry, int key);// Precondition: size( ) < CAPACITY, and the // bag does not yet contain any item// with the given key.// Postcondition: A new copy of entry has// been added to the bag, with the given key. When the programmer wants to remove or retrieve an item from a keyed bag, the key of the item must be specified rather than the item itself. The keyed bag should also have a boolean method that can be used to determine whether the bag has an item with a specified key. In a keyed bag, the pro- grammer using the class specifies a particular key when an item is inserted. Here’s an implementation idea: A keyed bag can have two private arrays, one that holds the string data and one that holds the corresponding…arrow_forward

Your program should find words like cAt that differ only in case. Have your program reject only lines that contain one or more of the three words exactly. For example, concatenation is a small category should not be considered profane. This problem can be solved easily. If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string.
