Write a java program that replace each line of a file  with its reverse. For example, we have in file this data: Hello I am world!  Hello world), Smart.  -if you run the output is: olleH !dlrow ma I .tramS,) dlrow olleH

The average-case performance for Shellsort is   a. O(n)   b. O(n1.5)   c. O(n2)   d. None of the above.

In Java Integer in is read from input. Write a while loop that iterates until in is less than or equal to 0. In each iteration: Update in with the quotient of in and 7. Output the updated in, followed by a newline.     Click here for exampleEx: If the input is 2401, then the output is:   343 49 7 1 0   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17     import java.util.Scanner;   public class QuotientCalculator { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intin;   in=scnr.nextInt(); /your code here/ } }

Write a program that obtains the executiontime of external sorts for integers of size 6,000,000, 12,000,000, 18,000,000,24,000,000, 30,000,000, and 36,000,000. Your program should print a tablelike this:

Gery lines can not be edited as seen on photo.  New JAVA code can only be added to they 14 - 16 or lines inbetween.

Write a java program that has the following 3 methods in addition to the main program. The main program should be interactive using a "do while loop". All input/out must be done in the main. 1. countLetter: Write a method, countLetter(...), that takes as parameter a sentence and letter and count how many times did the letter appear in the sentence. In the main the sentence are read from a file which contains many sentences and letters. Input file This is an example i The output of your program should be one of the following sentence 0 It is a palindrome or it is not a palindrome m

In Java: -Using a BST Interface (Binary Search Tree)  -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…

Write a Java program to read in a list of integers from the user and then output the average of those integers. Make sure to handle any potential exceptions that could occur during input.

In Java:  Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
