Jump to level 1 Given string userString on one line, character charToFind on a second line, and integer strindex on a third line, output "Match found" if the character at index strindex of userString matches charToFind. Otherwise, output "Match not found". End with a newline.

Rules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().
IN JAVA Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount ("abcde") → 0 duplicateCount ("aabbcde") → 2 duplicateCount ("Indivisibilities") → 2 duplicateCount ("Aa") → 0 // Case sensitive
Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.
Method: sumOdds(value: int): This method will sum all the odd values from 1 upto the value passed by parameter. This will display the sumas an integer value.Method: characterCount(phrase: str): This method will count the number of characters in the phrase that is passed by parameter. You cannot useany built in function ( ie len() ) and must use a looping activity. This should display the number of characters inthe phrase as an integerMethod: multiplicationPractice(): This method is to practice simple multiplication problems. The program should randomly generate twonumbers from 1-10 for the user to multiply. It should display the multiplication problem and allow the user toanswer the problem. It should display if the user got the answer correct or incorrect. The activity shouldcontinue until the user has gotten 3 different practice problems correct.Method: order(value1: int, value2: int, value3: int): This method is to order the 3 passed value from least to greatest. It should display…
KOI is offering a new laptop rental service. You need to create an application to allow an IT person to create reservations for students. You will need to use classes and Lists. Create a program that will ask the student ID, Name, Rental Start Date and End Date. It will use Reservation class object to save these 4 parameters (using a constructor). Reservation object will then be added to a List. The class will also have a method to calculate the rental($1 per day). - The program will keep asking if more reservations need to be entered(Y/N). - For each reservation it will create the object and save it in a list. - Once all reservations have been entered it should display the reservation details including the rental cost for each reservation in a tabular format,must be done injava netbeans
Given string userString on one line, character charToFind on a second line, and integer strIndex on a third line, output "Found match" if the character at index strIndex of userString matches charToFind. Otherwise, output "No match". End with a newline.

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 setString(String string)…
Make any necessary modifications to the RushJob class so that it can be sorted by job number. Modify the JobDemo3 application so the displayed orders have been sorted. Save the application as JobDemo4.
