COMPARING THE EFFICIENCY OF THE STRING
AND STRINGBUILDER CLASSES
Step by step
Solved in 2 steps
- COMPARING THE EFFICIENCY OF THE STRING AND STRINGBUILDER CLASSESSolution 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)The String class implements Comparable, which means that two strings can be compared to each other. However, the default implementation orders strings based on the ASCII values of their characters, which means that strings that begin with an uppercase letter are always ordered before strings that begin with a lowercase letter. This means that the string “Zoo” would be ordered before the string “aardvark”. Write a Comparator that compares two strings alphabetically so that “aardvark” is ordered before “Zoo”. Hint: convert both strings to upper or lowercase before comparing them.
- Create a subroutine that takes a noun-verb-object straightforward phrase and breaks it down into its component components. For instance, the phrase "Mary walked the dog" is broken down into the following:Noun: MaryVerb: walkedObject: the dogBoth StringBuilder objects and String objects should be compatible with this method.Write in C Language Spilitology Yosef is a peculiar fellow. He introduced the idea to study a string by splitting it into two, and he called it Splitology. Why split a string? We do not know. Didn’t we say that Yosef is a weird one? Yosef is interested in one particular type of string, a palindrome. A palindrome is a string that is the same for both forwards and backwards. Example of palindrome strings are “ada”, “taat”, and “radar”. On the other hand, string such as “taman” is not a palindrome; notice that “taman” becomes “namat” if read backwardsand it’s not the same as “taman”. As the idea of Splitology is still new, Yosef is investigating whether a string can be split into two non-empty strings such that each string is a palindrome. For example, the string “malamini” can be split into “malam” and “ini” while both of them are palindrome. Another example is “ababab”. It can be split into “aba” and “bab”, and both of them are palindrome. Note that “ababab” can also be split into…Create a subroutine that breaks down basic noun-verb-object sentences into their component parts. For instance, the phrase "Mary walked the dog" is broken down into the following: Noun: MaryVerb: walkedObject: the dog Both StringBuilder objects and String objects should be compatible with this method.
- Instructions Overview We have been working on replicating the immutable Java String class (MyString class). In this assignment, you will provide two different versions that replicate the mutable Java StringBuilder class. Both classes will provide all the methods specified by the MyStringBuilder interface, including the length, charAt, and toString methods supported by the MyString class we implemented in class. Both classes will add a constructor that takes a MyString object as a parameter. Additionally, they will implement the attached MyStringBuilder interface. MyStringBuilderArray class You can start the MyStringBuilderArray class which inherits from the MyString class we've been working on in class. Make the instance variable characters in the parent class (MyString) from private to protected to facilitate the access to the variable in the child class (MyStringBuilderArray). Complete the implementation of all the methods appropriately. MyStringBuilderList class You can start the…package ch08.apps;import ch08.maps.*; public class HMapDriver { public static void main(String[] args) { boolean result; HMap<String, String> test; test = new HMap<String, String>(10,0.75); /*String s = null;test.put(s,"value");test.put("s",null);System.out.println("Expect 'null':\t" + test.get("s"));System.out.println("Expect 'true':\t" + test.contains("s"));test = new ArrayListMap<String, String>();*/ System.out.println("Expect 'true':\t" + test.isEmpty()); System.out.println("Expect '0':\t" + test.size()); System.out.println("Expect 'null':\t" + test.put("1", "One")); System.out.println("Expect 'false':\t" + test.isEmpty()); System.out.println("Expect '1':\t" + test.size()); System.out.println("Expect 'One':\t" + test.put("1", "One")); System.out.println("Expect 'false':\t" + test.isEmpty()); System.out.println("Expect '1':\t" + test.size()); test.put("2", "Two"); test.put("3", "Three");…Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing. The String class has a lot of functions and continues to grow. See https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create a java program that when give a sentence will replace the first occurrence of NUST with Namibia University of Science and Technology. Sample run 1: --- Input ---Welcome to my NUST --- Expected output (text)---Welcome to my Namibia University of Science and Technology. Sample run 2: --- Input ---The nust is a great institution of high learning. --- Expected output (text)---The Namibia University of Science and Technology is a great institution of high learning. Sample run 3: --- Input ---The NuSt was renamed from Polytechnic Of Namibia under Act No. 7 of 2015. --- Expected output (text)---The Namibia University of Science and…

Output: The Namibia University of Science and Technology is a great institution of high learning.A class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:str2 = str1.concat;The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3. Write Java code to put the circumstances given into effect.Write a string class. To avoid conflicts with other similarly named classes, we will call our version MyString. This object is designed to make working with sequences of characters a little more convenient and less error-prone than handling raw c-strings, (although it will be implemented as a c-string behind the scenes). The MyString class will handle constructing strings, reading/printing, and accessing characters. In addition, the MyString object will have the ability to make a full deep-copy of itself when copied. Your class must have only one data member, a c-string implemented as a dynamic array. In particular, you must not use a data member to keep track of the size or length of the MyString. Here is a list of the operations this class must support: A length member function that returns the number of characters in the string. Use strlen(). Construction of a MyString from a const c-string. You should copy the string data, not just store a pointer to an argument passed to the…
