- Write a code that generates a random lowercase letter. In java programming.IN JAVA. Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 15 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.
- 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 IN JAVA USING JOptionPane.showInputDialog Write a program that reads a sentence as input and converts each word to “Pig Latin”. In one version of Pig Latin, you convert a word by removing the first letter, placing that letter at the end of the word, and then appending “ay” to the word. Here is an Example: English: I SLEPT MOST OF THE NIGHT Pig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY EXAMPLE:Write a code in Java that results like test 1&2.
- Write a java program that simulates a vending machine. Products can be purchased by inserting coins with a value at least equal to the cost of the product. A user select a product from a list of available products, add coins, and either gets the products or gets the coins returned. The coins are returned if insufficient money was supplied or if the product it's sold out. The machine does not give change if too much money was added. Products can be restocked and money remove by an operator. Your solution should include a class VendingMachine that is not coupled with the Scanner or PrintStream classes.

Print out the number code of each letter from the input in reverse . 4. Ask if the operation should be done again, if Yes, Return to 1. if No. Terminate the program 5. Create at least 2 methods aside from your main method in implementing a solution for this problem.Write in Java and use JOptionPane.showInputDialog Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. When the program begins, a random number is ranged of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper, If the number is 3, then the computer has chosen scissors. (Don’t display the computer’s choice yet.) The user enters his or her choice of “rock”, “paper”, or “scissors” at the key-board. (You can use a menu if you prefer.) The computer’s choice is displayed. A winner is selected according to the following rules: If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) If one player chooses paper and the other player chooses rock, then paper wins.…Write a Java program that reads a number from the command line and checks whether it is a prime number.
