Write a method that takes a given string and replaces all occurrences of one string with another string, returning the number of replaces made. For instance, given the string “Microsoft” if you were to replace all occurrences of “ic” with “MSFT” the result would be “MMSFTrosoft” with a return value of 1. As part of a final solution please provide unit tests done as well as any test cases ran. Please note that you may not use String.Replace or string:replace depending upon the language you use; you must write this functionality yourself.
a) Write a method encrypt(String text, int key) that returns a String. This method does two things to thestring text:1. First, it reverses the order of its words (“hello there” becomes “there hello”).2. The second thing is incrementing the characters’ ascii code by key. For example, if the key isequal to 2, “hello” becomes “jgnnq” (since ‘h’ + 2 = ‘j’ and so on). Note that this second stepdoes not apply to the space character so a space remains a space.For example, "Humming birds" for a key equal to 4 becomes: "fmvhw Lyqqmrk".b) Write a test program that prompts the user to enter a line of text and a key then calls the methodencrypt to display the encryption of the input text.
How do I add, If s is null, the method should return null. If s is the blank string, “”, the method should return the blank string to my code? import java.util.Scanner;public class replaceFirst { public static String replaceFirst(String Str,char c) { Str = Str.substring(0,0) + c + Str.substring(0 + 1);// modified string return Str; } public static void main(String[] args) { System.out.print( replaceFirst("basant",'c')); } }
write a public static method named replaceFirst that takes in a String s and a char c as arguments. The method will return a modified String replacing the first character with the one that was passed in. (Do not print out the String) Special cases: If s is null, the method should return null. If s is the blank string, “”, the method should return the blank string. Example: Replace.replaceFirst(“make”, ‘t’); Returns: “take” Replace.replaceFirst(“a”, ‘x’); Returns: “x” Java tests: Test replaceFirst(null, char c) replaceFirst("", char c)keyboard_arrow_up replaceFirst(String s, char c)Unit testkeyboard_arrow_down
Write a method that returns anumber, given an uppercase letter, as follows:public static int getNumber(char uppercaseLetter)Write a test program that prompts the user to enter a phone number as a string. The inputnumber may contain letters. The program translates a letter (uppercase or lowercase)to a digit and leaves all other characters intact. Here are sample runs of the program: Enter a string: 1-800-Flowers ↵Enter1-800-3569377
Exercise 3.8 >The following method returns the longest substring that appears at both the beginning and the end of the string without overlap. For example, sameEnds("abXab") returns "ab". public class SameEnds { public String sameEnds(String string) { int length = string.length(); int half = length / 2; String left = ""; String right = ""; int size = 0; for (int i = 0; i < half; i++) { left = left + string.charAt(i); right = string.charAt(length - 1 - i) + right; if (left.equals(right)) { size = left.length(); } } return string.substring(0, size); } } This is a software testing exercise. Apply the domain testing to the above program. Clearly state all steps of domain testing. Thank you so much.
Write a method that finds the number ofoccurrences of a specified character in a string using the following header:public static int count(String str, char a) For example, count("Welcome", 'e') returns 2. Write a test program thatprompts the user to enter a string followed by a character then displays the numberof occurrences of the character in the string.
Print person1's kids, call the incNumKids() method, and print again, outputting text as below. End each line with a newline.Sample output for below program with input 3: Kids: 3 New baby, kids now: 4 // ===== Code from file PersonInfo.java =====public class PersonInfo {private int numKids; public void setNumKids(int setPersonsKids) {numKids = setPersonsKids;} public void incNumKids() {numKids = numKids + 1;} public int getNumKids() {return numKids;}}// ===== end ===== // ===== Code from file CallPersonInfo.java =====import java.util.Scanner; public class CallPersonInfo {public static void main(String [] args) {Scanner scnr = new Scanner(System.in);PersonInfo person1 = new PersonInfo();int personsKid; personsKid = scnr.nextInt(); person1.setNumKids(personsKid); /* Your solution goes here */ }}// ===== end =====
A pentagonal number is defined as n(3n-1)/2 forn = 1 , 2 , …, and so on. Therefore, the first few numbers are 1, 5, 12, 22,. . . . Write a method with the following header that returns a pentagonalnumber:public static int getPentagonalNumber(int n)For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display thefirst 100 pentagonal numbers with 10 numbers on each line. Use the %7d formatto display each number.
can you please write in java.util.scanner form and can you make it so i can copy and past it please Create a method public static String[] mergeArrays(String[] arr1, String[] arr2) where arr1 and arr2 are two String[]. The method should return one String[] array which is the concatenation of arr1 and arr2. Test this out in the class' main() method.
Q1) 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.
create a class that asks a user for 2 string inputs (USE The Java. Util. SCANNER) -compare the two strings and output if they are equal or not. -check the length of the 2 strings. then compare the two (in terms of length) -thereafter, for the largest string, ask the user to input a character and determine if the string contains that specific character ..... e.g. The word is "star" and the user enters 'a'. The program should output either True or False 2) Create another method within the same class that will check if a sequence of characters (String) entered by the user to determine whether or not the String contains that specific sequence. -You can use the user input from Q1 to determine if the string contains the sequence of characters. You need to create atleast 2 methods (excluding the main method). Atleast one Method needs to take in argument and return some value 3) Create a Person class that…
