Implement the Plates class buildMap function so that it populates the HashMap with the state abbreviations as keys and the counts of how many each appear in the file as values.
Sometimes, the parking attendant will add special notation to help her remember something about a specific entry. There are just non alphabetic characters that she adds to the state - your program should ignore these characters so that an entry like NY* still counts toward the NY plate count.
She is also very inconsistent with how she enters the plates. Sometimes she uses upper case, sometimes lowercase, and sometimes she even uses a mix. Be sure to account for this in your program.
Only add information for plates in New England (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut).
Plates.java
import java.util.Arrays;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;
public class Plates {
private Map<String, Integer> plateMap;…

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.".
There are 5 methods that need to be implemented in the CustomString class:
● getString() - Returns the current…
Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences.
Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below.
Sample Input:
Text string: You will always have my love, my love, for the love I love is as lovely as love itself.
Pattern string: love
Output:
New text: You will always have my LOVE, my LOVE, for the LOVE I LOVE is as lovely as LOVE itself.
Number of occurrence: 5
For example:
Input
Result
You will always have my love, my love, for the love I love is as lovely as love itself. love
New text: You…

- For this problem, you can use all classes in the java.util package. As a genius IT/SE student, you are asked by the Ministry of Health to help them analyze the Covid sequences. In particular, given 2 Covid variants, your task is to find the longest common subsequence between them. Each Covid variant has 2 properties: code (String) and sequence (String). Both properties contain only upper case letters 'A' to 'Z'. The length of the sequence is up to 100 characters. Subsequence definition: given a string S consists of the letters s1, s2, sn in that order. If you delete zero, one, or more letters from S without changing the letters' order, the remaining string S2 is called a subsequence of S. For example: given the string "HELLO", the following strings are some of its subsequences: "HELLO", "HLO", "O", "HO", "'" (empty string). The following strings are not its subsequences: "OL", "HELLOO", "LEH". Create a type CovidVariant that contains 2 properties: code (String), and sequence (String).…arrow_forwardImagine you are reading in a stream of integers.

- Solution in Java Implement a method removeWord() that takes two string parameters: sentence - the sentence you are to remove a word from. word - the word you are to remove from the sentence. Your method should take a string, sentence and remove word from it. It will return a new string without word in the sentence. Examples removeWord("One two three four", "two") → "One three four" ● removeWord("Bob has a kid", "kid") → "Bob has a" (Ctrl)arrow_forwardImport the HashMap and Map classes from the java.util package. Within the main method, a sentence is declared as a string variable and assigned the value "This is a test sentence with no repeating words". Split the sentence into words using the split method and store the result in a String array called "words". Create a new Map called "wordFrequency" that stores each word as a key and the frequency of the word in the sentence as the corresponding value using the HashMap implementation. Use a for loop to iterate through each word in the "words" array. Within the for loop, the code should use the containsKey method to check if the word is already in the Map. If the word is already in the Map, its frequency should be incremented by 1. Use the put method to add the word as the key and the incremented frequency as the value to increment it. If the word is not in the map, add it as a new key with a frequency of 1 as its value. Outside of the for loop, use System.out.println to…arrow_forwardComputer Science Use only NumPy to create the Normalize Class: Image Normalization is a technique used to touch up images that are too dark or too light for the human viewing experience. Implement a version that outputs images with full dynamic range (0–255 pixel intensity). In other words, for each color channel (r, g, b), rescale the range of pixel values for that channel to include both 0 and 255. After normalizing, there should be at least one pixel with a red value of 0, at least one pixel with a red value of 255, at least one pixel with a green value of 0, etc. To normalize a list of numbers nums to the range 0–n, set nums[i] = (nums[i]−min(nums))/(max(nums)−min(nums))∗n for all i. Be careful! When max(nums) == min(nums), you should not touch that list (why?).arrow_forward
