2D Arrays - Word Search?
Dec 14, 2014
Okay, so the assignment was creating a word search for the given array. I've created all the code necessary, but I've ran into trouble. This problem occurs with the Up-Forward, Up-Backward, Down-Forward, and Down-Backward sections. If I only set one of these to run, it works. But if I have all 4 set at the same time, it errors out on the first one that runs.
public class P_WordSearch {
public static void main(String[] args) {
char[][] puzzle = {
{'B','O','O','G','S','R','O','W','I','N','G'},
{'E','B','L','G','N','I','M','M','I','W','S'},
{'L','C','E','A','T','I','P','U','P','I','S'},
{'C','M','I','N','C','A','X','Y','O','S','N'},
[Code] ....

Consider in a Document if a String " Hello" is Encoded and stored as "XYZAB"
I want to search the text on document for a word "Hello" and Replace the word with "HelloWorld"
The Program will encrypt the word "Hello" and Search the file then return the encrypted code as "XYZAB" Found
Now i have to replace the word "Hello" with "HelloWorld" in encrypted form so that the Letter "XYZABEFGHI" is replace in the place of Hello where "World" is encoded as "EFGHI"
Now the Problem is If there is more number of occurrence of the word "Helloworld" exist in the file... How can i Replace only one particular occurrence What can be done to select the particular occurrence.
I have attached my java program for Encryption along with this mail for your ease of use.

Coding (must follow pseudocode algorithm provided) for comparing characters of a word to a puzzle board char[][].
I've gotten the horizontal and vertical searches to work, but I'm having a difficult time figuring out how to search diagonally.
Here's the search algorithm format I have to use:
for each guess word
for each letter of the puzzle
for each letter of the guess word
check for diagonal match
if found, add word to list, break to next guess
I'm assuming there should be a +1 horizontal offset after I find the first letter, but every index I've bumped has caused me to screw up my array bounds. I'm missing something.
Here's the algorithm I'm using for diagonal search. This same algorithm worked for vertical search (minus the offset of course)
//diagonal search
for(String word : guessWords) {//for each guess word
int letterCount = 0;
int index = 0;
for(int j=0; j<grid[index].length; j++) {//for each puzzle letter

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?
import java.util.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class WahidMuhammadA3Q2{
String fileName = "AutoCorrectMe.txt";

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?

I'm trying to build a method that can search a binary search tree for a specific target and then return the number of probes it took to get there. It seems to me that the best way to do this would be a recursive search method and a counter that tracks the number of calls. But I'm struggling with how to implement this. Here's the code I have so far. what works/doesn't work with the method.
// Method to search the tree for a specific name and
// return the number of probes

So the exercise I'm working on says to have the user enter their name and the program will output their name with the last name in all caps. i made it work BUT the only way i could figure it out was to ask for the first and last names separately creating two strings rather than one.
Of course I want to make it work how it's supposed to (with one string) so that I'm learning. I'm just having trouble conceptualizing how exactly (with varying lengths of names) to tell the program to only capitalize the second word... at first I thought create a substring beginning with the first letter of the last name and ending with the last...but again, therein lies the issue of varying name lengths.
is there a way to create a substring that beginIndex's at the first "space"? then i could just leave the endIndex parameter empty and it would take the whole word into a new string. and from there utilize toUpperCase to the new string?
Here's my code asking for the first and last names separately.
import java.util.Scanner;
class nameEcho {
public static void main ( String [] args ) {
Scanner scan = new Scanner( System.in );
String first;
String last;

I was tasked with building a program that, when is given a string by the user, takes it and prints it out as a rectangle. For example, if the user types in "COMPUTER", the output would be:
COMPUTER
OMPUTERC
MPUTERCO
PUTERCOM
UTERCOMP
TERCOMPU
ERCOMPUT
RCOMPUTE
So far, I have created 2 separate strings, and have gotten the output to look like:
COMPUTER
OMPUTERC
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
So, it works once, but then it doesn't work again. Here is my code:

String input = new String("The Dogman was no ordinary dog, nor man, but rather a peculiar dog-like man who barked like a dog, and panted like a dog, he even ate like a dog. He owned a dog named Doglips, and interestingly enough, his favorite food was hotdogs.");

I recently have tryed to make a java code that reads words and say if its palindrome or not. I want to fix two things but unfortunately i can't do it on my own.
1st thing that i want fix is that when i run the code i have to press 2x times enter..and i dont know why?(i want one time to press it when i write the text)
2nd thing that i want to fix is that when you run it you can put as many words as you can..only when you write "END" the code must ends.
So unfortunately my code runs only for 1 time.(one word)
My code:
class test {
public static void main(String args[]) {
System.out.print( "#Enter text : " );
String text = BIO.getString();
String reverse = BIO.getString();
int length = text.length();
[Code] .....

What I need to do is ask the user to input some text and then turn it into pig latin. I am confused on how to select each word from the string to determine if it ends in a way or ay. I am to assume that the letters are all lowercase and the text ends with a period.
import java.util.Scanner;
public class Trial

public static void main(String [ ] args)

I am in an intro programming class and we got assigned a problem for creating a super class with about a dozen sub classes for generating a random word(via WordGetter class) and then comparing that word to a variety of different patterns(like: does the word contain "re"). We were given the super class which looks like this...
public class Pattern {
public boolean matches(String text) {
return true;
}
public String toString() {
return "(TRUE)";
[code]...
and from this class, we have to write subclasses that override those three methods. I am struggling to understand inheritance and I am not really sure where to even start. Here is the instructions for the first sub class we need to write...
"CONTAINS" SUBCLASS
Constructor: The constructor accepts a String named ‘letters’.
Matches: This pattern matches any text that contains at least one occurrence of each ‘letter’.
toString: produces the text “(CONTAINS <LETTERS>)” where <LETTERS> is the ‘letters’ string.
getLetters(): this method must return letters.
equals(Object): careful on this one. Two Contains are equal if they have the same letters (order is not relevant).
(Example):
Pattern p = new Contains(“re”);
boolean f1 = p.matches(“renew”); // f1 is true
boolean f2 = p.matches(“zoo”); // f2 is false
String s = p.toString(); // s is “(CONTAINS re)”
boolean f3 = p.equals(new Contains(“er”)); // f3 is true.. really..
