Write a program to reverse each word in line(sentence)?
View Replies View RelatedI've been given an assignment for my Programming Fundamentals class that requires the user to enter a word/sentence to encrypt or decipher, as well as requiring the user to enter a key in which to encrpyt/decrypt the input by.
So a = no shift, b = a shift by 1 and so on.
But I'm completely lost as to what to do, and after searching for Vigenere Cipher topics, they look completely different to mine and (hardly) include prompts?This is my code:
/**
* @(#)VigenereCipher.java
*/
import java.util.Scanner;
public class VigenereCipher
{
public VigenereCipher()

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;
[Code] ....
The intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected. So lets say I have a text file containing "My name is OP and I Like goind to the Park!" I want to change "goind" to "going",
Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?

I am looking for java codes to generate a word document based on a word template, basically, I have a word template created and in my local path, the template has a proper format with some fields which will be filled in after java codes ran. The java codes will fetch one record from a table, and open the word template and then fill the fields in the word template, and created a new word document and save it in another folder.
I found this example: [URL] which is similar except it uses xml template instead of word template, how to make it work to change the template from xml to word (docx) template?
Here's My Code.

I am trying to get it to compare the word I type in to the set word in the object 'secretword'. I have tried everything from equal to == to compareTo, I even created a two hundred line program to do this SIMPLE problem.

I am having an issue deleting a node for a tree for one of the cases.The cases for deleting a node are:
1. if its the root set it to null
2. if its a leaf, have its parent point to null
3. if the node you want to delete does not have a right child, have deleted nodes parent point to delted nodes only child
4. find the nodes predecessor(next largest value), have have predecessor's left child be deletes left, and preds right to be deletes right. then have deletes parent point to pred and finally, delete preds old spot (the one that is giving me an issue, I believe)
The pre order of the tree I am currently on is 50 5 4 10 190 100 100 200 190 201
or------------------50
-------------5--------------190
---------4------10-----100-------200
--------------------100---190--201
I am trying to delete 190 (which should be the first one)but when I try to print out the list after I delete, I get a stack overflow error when I try printing everything out.I am pretty sure that it has something to do with me hooking up the nodes incorrectly since error occurs for case 4, since it prints out just fine when I deleted previous nodes (like a leaf).Here is my delete method: (note, ignore my determineX and checkOtherHalf methods)
public boolean delete (E item) {
if(root == null){
return false;
else if(item == root){
root = null;
return true;
[code]....
I have confirmed that it is a pointer issue: I need to assign replacements old parents left child to null, to stop it, but idk how.Here is a screen shot of it when I debug it
I've a ArrayList with dogs on, and I've a function that should allow me to delete a dog from the register and if the dog was found it prints "The dog was deleted" and if the dog doesn't exist in the arraylist it should print "the dog couldn't be found".
Everything works perfect until I shall delete a dog that is not first on the list. Then the program shows first "dog was not found" and on the row after "the dog was deleted" if the dog was second on the list. If it was third I will get 2 messages that the dog wasn't found and then that the dog was deleted. I've no clue why it prints both else and if!
public static void taBortHund(){
//Har tar vi bort hund fran listan
//System.out.println(hundlista);
System.out.print("Vilken hund vill du ta bort? ");
String hunden = tangentbord.nextLine();
for (int taBort = 0; taBort<hundlista.size(); taBort++){

ok so for class I'm supposed to Write a class DeleteElements that prints out an array and asks the user which number should be deleted and then deletes that number, if it exists from the array.
The first part tells me to
Step 1
o Start by simply searching the element.
o Pseudocode:
-Create an array and populate it with random positive integers.
-Print the array to show the user which elements the array contains.
-Use a WHILE loop to search the element—a WHILE loop is better than a FOR loop because you can stop when the element is found by using a Boolean value in the loop condition—and also keep track of the location where the
element might be found.
-If the element is not found, output the error message, “Number not found.”
-Otherwise output the message, “Number found at index #.” where # is the index where the element is.
-Print out the array.
Example of output:
34 65 12 76 45 39 86 71 67
Number to delete: 76
Number found at index 3
This is what I've got so far but I can't seem to get the "number not found part to print out only once".
import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;
public class DeleteElement {
public static final int ARR_LENGTH = 10;
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Random ran = new Random();
[Code] ....
Current output result if value does not exist:
61 89 52 16 20 71 37 91 4 36
Number to delete:
23
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Number not found.
Current output result if value exists:
97 48 51 22 89 5 42 97 43 96
Number to delete:
89
Number found at index 4
Maybe I'm not understanding the part about the boolean value.
How do I write a program that has words in an array and output that array without the vowels?

Working on my final which is due today, its' and Inventory Program which I have been working on for the last 5 weeks. My Buttons on my GUI Add/Delete doesn't add items to my inventory. I'm not sure exactly what wrong with my code, I'm not getting any error and the Program compiles just fine, I just can get the Items to add of delete.
my Delete button starts on line 281
my Add Button begins on line 319

My method below works fine to print a matrix but when it prints every row, it is printing extra 4 white spaces which is not required. How can I delete those extra spaces at the end? when I use
System.out.print((matrix[i][j] + " ").replaceAll("^s+", ""));
It trims every thing including the spaces I needed for my matrix. So where should I put replaceAll("^s+", "") ?
Java Code:
private static void printMatrix(int[][] matrix) {
System.out.println();
System.out.println("Matrix:");
for (int i = 0; i < matrix.length; i++) {
for (int j = 0; j < matrix[i].length; j++) {
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}

My current lesson in Java is about ArrayLists and I'm having a tough time to understand this bit of code: This exercise is concerned with the problem of deleting a block of items from an ArrayList.

{
if ( strings.size() > 0 )
strings.remove( i );

how to split and then represent the splitted sentence.Suppose I have:
Java Code:
String sentence = "I Love my mother <=> I Love my father";
String[] array = sentence.split("->"); mh_sh_highlight_all('java');
But how can I get now the lefthandside String values which is "I love my mother" and righthandside "I love my father"? I tried smth like:
Java Code:
String[] leftHandSide = array[0].split(" ");
String[] rightHandSide = array[1].split(" "); mh_sh_highlight_all('java');
But it's not working - getting error.

What this do is:
First write out the whole sentence (WORKS)
Write out number of words (WORK)
Then I would like it to write out number of characters (DOESN'T WORK)
The arguments are given in "run configurations" using eclipse
