UOWD 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 in Java programming
You are working in a company, and your new task is creating an encoding algorithm to secure a given data. Given a code, write a method called encode() that takes a String and returns a new String based on the frequency of the characters.
All the even-frequency characters should be placed before the odd-frequency characters, and finally, all characters should be sorted in increasing order.
Your colleague is sick again, and he cannot finish his task. He gave you an unfinished code like the following:
public static String encode(String code) {
// MyFunction mf = // TODO
return mf.encode(code);
}
Your job is to complete the implementation of the functional interface MyFunction that encode() method should use to encode the given String code.
The MyFunction interface should have the following signature:
interface MyFunction {
String encode(String code);
}
Additionally, your algorithm should handle the following cases:
1. If the input String is null, the…

- Answer plzarrow_forward: Imagine you are reading in a stream of integers. Periodically, you wish to be able to look up the rank of a number x (the number of values less than or equal to x). Implement the data structures and algorithms to support these operations. That is, implement the method track(int x), which is called when each number is generated, and the method getRankOfNumber(int x), which returns the number of values less than or equal to x (not including x itself). EXAMPLE Stream (in order of appearance): 5, 1, 4, 4, 5, 9, 7, 13, 3 getRank Of Number (1) = 0 getRankOf Number (3) = 1 getRankOfNumber (4) = 3arrow_forwardCreate a Generator that generates a stream of random numbers.Following a reset call, the random sequence is "rewound" to return the same sequence. Various sequences should be generated by separate generators.(Hint: You might find the setSeed function of java.util.Random interesting.)arrow_forward
- You are required to implement a preprocessor in Java. Your preprocessor should be able to Identifying loops and methods on an input file, which will be a Java source file. (please i need clean code) Examplearrow_forwardWrite a Java Code for two files: PangramCheckerTest.java, PangramChecker.java Instructions: Determine if a sentence is a pangram. A pangram (Greek: παν γράμμα, pan gramma, "every letter") is a sentence using every letter of the alphabet at least once. The best known English pangram is: The quick brown fox jumps over the lazy dog. The alphabet used consists of ASCII letters a to z, inclusive, and is case insensitive. Input will not contain non-ASCII symbols.arrow_forwardYou are required to implement a preprocessor in Java.

- Java: Class: MiddleStr Write a method public static String middle(String str) that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd". Write a test program [main()] to test the method.arrow_forwardIn Java, Write an application that reads a line of text, tokenizes the line using space characters as delimiters and outputs only those words beginning with the letter "b". Javaarrow_forwardWrite a program that prompts the user to enter adecimal number and displays the number in a fraction. (Hint: read the decimalnumber as a string, extract the integer part and fractional part from the string,and use the BigInteger implementation of the Rational class in Programming to obtain a rational number for the decimal number.) Here are somesample runs: Enter a decimal number: 3.25 ↵EnterThe fraction number is 13/4 Enter a decimal number: –0.45452 ↵EnterThe fraction number is –11363/25000arrow_forward
