WRITE CODE IN JAVA 1. Write a program called reverseNums that takes user for a single long positive integer. The program shall read the input as integer; and print the "reverse" of the input integer. For example: Enter a positive integer: 12345 The reverse is: 54321 2. Write a program or a method of your own name, which asks for user input of a String object, and prints the reverse of the string by extracting and processing each character. The output would look like this: Enter a String: abcdef The reverse of the String "abcdef" is "fedcba".

Hello. I can't get this Java code to work. It takes a series of sentences as a single string. The function capitalizes the first letter of every sentence What am I doing wrong? /*Programming ChallengesChapter 9 #3 Pg. 608 Title: Sentencee CapitallizerWrite a method that accepts a String object as an argument and returns a copy of the stringwith the first character of each sentence capitalized. For instance, if the argument is “hello.my name is Joe. what is your name?” the method should return the string “Hello. My nameis Joe. What is your name?” Demonstrate the method in a program that asks the user toinput a string and then passes it to the method.

Write a java class method named addQuotes that takes one parameter of type String. The method should return a string that's indentical to it's argument, but with a double quote character added at the beginning and end of the string.
Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines. Example Execution (user input in green) Please enter a sentence: Hey there! Your sentence printed vertically is: H e t h e r
USING JAVA Write a Java method named check() that checks the validity of a password received as string parameter. To be valid, a password should contain at least: 3 letters, 2 digits, and 1 character from {‘-’, ‘_’}. If the password is valid the method returns true, otherwise it returns false. To test your method, write a main() method that enables the user to input a password as a string, removes eventual extra spaces from it, sends it to check(), and displays the returned decision (the password is valid or not). Hints: To check if a character c is a digit you can use Character.isDigit(c), and to check if it is a letter you can use Character.isLetter(c). Run Example 1: Enter a password to check (at least 2 digits, 3 letters, and one char (- or _)): p5t4_i The password is valid. Run Example 2: Enter a password to check (at least 2 digits, 3 letters, and one char (- or _)): i0z#-9k The password is not valid.
In Java, Write an application that reads a line of text, tokenizes the line using space characters as delimiters and outputs only those words beginning with the letter "b". Java
Write a program that prompts the user to enter adecimal number and displays the number in a fraction. (Hint: read the decimalnumber as a string, extract the integer part and fractional part from the string,and use the BigInteger implementation of the Rational class in Programming to obtain a rational number for the decimal number.) Here are somesample runs: Enter a decimal number: 3.25 ↵EnterThe fraction number is 13/4 Enter a decimal number: –0.45452 ↵EnterThe fraction number is –11363/25000

Write the program that has two subroutines: one that builds a String object of a specified size and another that builds a StringBuilder object of the same size. Each of the subroutines is timed, using objects from the Timing class we developed at the beginning of the book. This procedure is repeated three times, first for building objects of 100 characters, then for 1,000 characters, and finally for 10,000 characters. The times are then listed in pairs for each size. code in c#
Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below)
modify it to create a classthat contains a static method; the method takes a string as a parameter andreturns a boolean value indicating whether the parameter string has repeatedcharacters in it or not. That is, return true if there is at least one characterwhich appear more than once in the string. The string should be input by the user public class Qns3 {public static void main(String args[]) { //input.Scanner Input = new Scanner(System.in);System.out.println ( "Enter the String to check for duplicate characters:");String k = Input.next();// repeated = true.boolean Repeat = false;for (int i = 0; i < k.length(); i++)for (int j = i + 1; j < k.length(); j++)if (k.charAt(i) == k.charAt(j))Repeat=true;if (Repeat){System.out.println("String have repeated characters" +k);}elseSystem.out.println( "String have no repeated characters" +k);} }
Please Use Java only. 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…
UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.
