- If str=‟Long String”, what will be the value of the following variables:
- String str1=str.substring(3,str.indexOf("i"));
- String str2 = str1.toUpperCase().substring(5)+str.substring(0,3);
- boolean test=str1.toUpperCase().indexOf(“r”) == str1.indexOf(“r”);

- 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: Complete the checkCharacter() method which has 2 parameters: A String, and a specified index (int). The method checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The method calls below with the given arguments will return the following Strings: checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"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 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.Create a method that returns a string where for every char in the original, there are two chars. Example: method ("wat") → "wwaatt"method ("java") → "jjaavvaa"method ("HelloWorld") → "HHeellooWWoorrlldd" Method declaration: public String method(String str){ //answers here }IN JAVA When people enter their telephone numbers into a form they use many different formats. Some examples are: (444) 999-1234 4449991234 444.999.1234 In the PhoneNumbers class below, complete the cleanNumber method. It takes a string and extracts the numeric digits from the string. If there are exactly 10 numeric digits, the number is reformatted: (###) ###-#### and returned. If there are any other number of digits, the string "Error" is returned. Hint: Use the Character.isDigit method to check whether a character is a digit. public class PhoneNumbers{ /** Cleans a phone number. @param phoneNumber a phone number that should contain ten digits and possibly other characters @return the phone number in the form (###) ###-#### or the string "Error" if phoneNumber does not have ten digits */ public String cleanNumber(String phoneNumber) { // your work here ... for (int i = 0; i < ...; i++) { char ch = phoneNumber.charAt(i);…
- 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.HELLO!
