Create a class MapTester (either in your current project or in a new project). In it, use a HashMap to implement a contacts list similar to the one in the example above. (Remember that you must import java.util.HashMap.) In this class, implement two methods: public void enterNumber(String name, String number) and public String lookupNumber(String name) The methods should use the put and get methods of the HashMap class to implement their functionality.
Write the method stringSplosion().* * The method takes one parameter, non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.*, @return a new String as described above.
Use for loops
In this problem you will fill out three functions to complete the Group ADT and the Diner ADT. The goal is to organize how
diners manage the groups that want to eat there and the tables where these groups sit.
It is important to take the time to read through the docstrings and the doctests. Additionally, make sure to not violate
abstraction barriers for other ADTS, i.e. when implementing functions for the Diner ADT, do not violate abstraction barriers for
the Group ADT, and vice versa.
# Diner ADT
def make_diner (name):
""" Diners are represented by their name and the number of free tables they have."""
return [name, 0]
def num_free_tables (diner):
return diner [1]
def name (diner):
return diner [0]
# You will implement add_table and serve which are part of the Diner ADT

- Implement a new concat method in the String class you worked on for HW2. The method should return a new String object that represents the text you would end up with if the argument String were "added onto the end of" this String. For example, in the code below, the String object answer should represent the text "bookstore" and true should be printed the screen. char[] bookA = {'b', 'o', 'o', 'k'}; char[] storeA = {'s', 't', 'o', 'r', 'e'}; char[] bookstoreA = {'b', 'o', 'o', 'k', 's', 't', 'o', 'r', 'e'}; String book = new String(bookA); String store = new String(storeA); String bookstore = new String(bookstoreA); String answer = book.concat(store); System.out.println(answer.equals(bookstore)); In the text area below, type in your definition of the concat method.

- Please assist with non graded problem. Create a Calculator class that implements sum, subtraction, multiplication, and division operations, and throws an appropriate exception whenever the user attempts to perform a division by zero. Then develop a graphical interface (with JavaFx) for your calculator using TextField, Button, and Label objects, or any other graphical objects you like. Graphically display division by zero errors.arrow_forwardPlease Use Java only. In this assignment, you will implement a simple class called CustomString. This class represents a more customizable version of a String, with additional attributes and methods. For example, the CustomString class has a “reverse” method which returns a new string version of the current string where the capitalization is reversed (i.e., lowercase to uppercase and uppercase to lowercase) for the alphabetical characters specified in a given argument. For CustomString “abc, XYZ; 123.”, calling reverse("bcdxyz@3210.") will return "aBC, xyz; 123.". The CustomString class also has a “remove” method which returns a new string version of the current string where the alphabetical characters specified in a given argument, are removed. For CustomString "my lucky numbers are 6, 8, and 19.", calling remove("ra6") will return "my lucky numbers e 6, 8, nd 19.".

Next-to-pairs appear next to each other, while combo-pairs cover every combination that can be found of pairing the strings.arrow_forward

Our lexer will start by reading the strings of the sample.txt file that the user wants to run. It will break the text file into “words” or tokens and build a collection of these tokens. We can consider the lexer complete when it can take any AWK file and output a list of the tokens being generated. Use Files.readAllBytes. This is a much simpler way of dealing with files. Example of readAllLines: Path myPath = Paths.get(“someFile.awk”); String content = new String(Files.readAllBytes (myPath); Start by creating the “StringHandler” class. It should have a private string to hold the document (sample.txt file) and a private integer index (the finger position). It should have methods: char Peek(i) -looks “i” characters ahead and returns that character; doesn’t move the index String PeekString(i) – returns a string of the next “i” characters but doesn’t move the index char GetChar() – returns the next character and moves the index void…arrow_forwardCan you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor.
