Chapter 8, Problem 2AW
Program Plan Intro
Substring:
- Substring is defined as a string within a string.
- String can also be said as the array of characters and in C# the individual characters present in a string can be accessed using the subscript notation.
- Substring method of the string object is used to retrieve a specific set of characters from a string.
Insert() method:
- This method is used to add a substring to the string and returns the string after the addition of the substring.
- Syntax:
- stringVariable.Insert(startPos, givenString)
Remove() method:
- This method is used delete substring from the given string. This method returns the string after removing the substring.
- This can be done in two ways:
- stringVariable.Remove(startPos): This step deletes the substring starting from the index number specified as “startPos”.
- stringVariable.Remove(startPos, count): This step deletes the substring starting from the index number specified as “startPos” but stops as the number of deleted elements reaches the count mentioned in “count”.

Write a method that accepts a String object as an argument and displays its contents backward.For instance, if the string argument is “gravity” the method should display -“ytivarg”.Demonstrate the method in a program that asks the user to input a string and then passes itto the method.
Write an application that reads a five-letter word from the user and produces every possible three-letter string that can be derived from the letters of that word. For example, the three-letter words produced from the word “bathe” include “ate,” “bat,” “bet,” “tab,” “hat,” “the” and “tea.”
In java language
Before we write a class which is used to describe objects, let’s practice manipulating an object by calling its methods.
Complete the class LeetMaker class using String methods. Remember that all the String methods are accessors. They do not change the original String. If you want to apply multiple methods to a String, you will need to save the return value in a variable.
Complete the class by doing the following:
Print the word in lowercase
Replace "e" with "3" (Use the unmodified variable word)
Print the changed word
In the changed word, replace: "t" with "7"
Print the changed word
In this newest changed word, replace: "L" with "1" (uppercase L with the number 1). Then, print the final changed word (with all the replacements)
Print the length of the word
The code to print the original word is already included for you. Do not change that statement. You will need to use the replace() method multiple times. Then print the final String. Remember that replace is an…

- Write a method that counts the number of letters ina string using the following header:public static int countLetters(String s)Write a test program that prompts the user to enter a string and displays the numberof letters in the string.arrow_forwardQ1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forwardCreate a method that returns a string where for every char in the original, there are two chars.

- Write a method that reverses a string. For example, 'java interview' becomes 'weivretni avaj'.arrow_forwardWrite a program that asks the user to enter a series of single-digit numbers with nothing separating them. The program should display the sum of all the single digit numbers in the string. For example, if the user enters 2514, the method should return 12, which is the sum of 2, 5, 1, and 4.arrow_forwardWrite a method with the following header to format the integerwith the specified width.public static String format(int number, int width)The method returns a string for the number with one or more prefix 0s. The size of thestring is the width. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns thestring representation for the number. For example, format(34, 1) returns 34.Write a test program that prompts the user to enter a number and its width, anddisplays a string returned by invoking format(number, width).arrow_forward
- In Programming When you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?arrow_forwardWrite a Java method called StringDay to display the String named day based on the number of the day. The method should take on integer argument and retum a Stringarrow_forwardThis program will classify a string as one of the following: a palindrome, a repeated word, or “nothing special”. A word is considered repeated if it repeats only once in a string (e.g., “pizzapizza”). Some palindrome examples are: “racecar”, “aa”, and “aaa”. To determine if it is a palindrome, recommend you make use of the below method. Please make sure this program works for all cases and conditions. /** * This method will return a reversed version of the input string */ static String reverseString(String inStr) { String outStr = ""; if (inStr != null) { int startIndex = inStr.length()-1; for (int i=startIndex; i >= 0; i--) { outStr = outStr + inStr.charAt(i); } } return outStr; }arrow_forward
- This method will return a string that when printed out will display a triangle. Each row of the triangle will have the next letter from the input argument as the last letter in the row. If the next letter is the noPrint char, * will print out instead of letters for the row. Can’t use System.out.println to print the calculated result in the method.
