My code compiles and runs just fine, i'd just like to get creating a small square box that shows number of words used next to the "word count = ". i'd wanto to press the count words button to count and show the number in the square box. here is my code.

public class wordCount extends JFrame implements ActionListener
Create a WordCounter class with a constructor that takes a file name as a parameter. The class should have two fields: one for the file name and one for a HashMap to store word count information. The constructor should call a private method, countWords, that reads in the file and counts the word frequencies. The class should contain a get method for each field, as well as a print method that prints out the map in the following format:word:frequency. When printing, the map should be sorted by either the word order or frequency (Hint: see Collections.sort)You should include the sample text file on Blackboard
import java.io.File; import java.util.ArrayList; import java.util.Collections; import java.util.HashMap; import java.util.Scanner; public class WordCounter
I am trying to create a method that prints the square root of a number up to a certain number. It needs to take a single int parameter for example "n" , and then print all of the (positive) even perfect squares less than n, each on a separate line. I want the method to be called something like this:
public void Squares(int n) { }
I need the output to look something like this:
Example: if n = 40, your code should print
4 16 36
So I have been working for a few hours now and am really stuck.
This is what I have so far:
int count = 0; int n = 4; int max = n; while(count < max) { System.out.println(n); n = n * n; count++;
One acre of land is equivalent to 43,560 square feet. Write a program that calculates the number of square feet in a tract of land with 3.5 acres. Hint: Multiply the size of the tract of land (in acres) by the number of square feet in an acre to get the number of square feet in the tract.
a) You must have a variable called nrAcres where you will store the number of acres in the track.
b) Output must look as follows:
Size of land in acres: 3.5 Size of land in square feet: 152460
c) if the value of the variable nrAcres is changed the output should change accordingly. In other words: it would be wrong to have the following statement:
System.out.println("Size of land in square feet: 152460");
previous statement will print the correct output but will not change if you change the value of nrAcres.

this is what i got so far
public class Land { public static void main(String[] args){ double nrAcres = 3.5; int feetInAcre = 43560; double feetInTract = nrAcres * feetInAcre; System.out.println("Size of land in acres: " + nrAcres + " Size of land in square feet: " + feetInTract); } }
i tried to compile it but it says
error: class names, Land, are only accepted if annotation is explicitly requested 1 error
I'm trying to create a cursor for a game that moves square by square. While it will move to the next square, though, it leaves the image of the previous cursor on the last square it was on.
As a visual explanation, this is what the program looks like on launch:
This is what it's suppose to look like after you press the right arrow key once (made by forcibly changing launch coordinates):
And this is what it actually looks like after you press the right arrow key once:
Here is the code for the program:

I'm fully aware that I could just use g.clearRect on the area and remove it for sure, but I know for a fact I shouldn't have to as I have another program I made a long time ago that tried to do something similar without needing to resort to that.
I am trying to make a program that get input value 1-200 from user. However I would like to make the program to show warning if the input number is not within the range of 1-200. In the end I would like to show the amount of number according to its interval (i.e less 50, 51-100 and so on) ....
import java.util.Scanner; class test { public static void main (String[] args) { int number[]= new int[5]; int number2[]= new int[5]; int a=0,b=0,c=0,d=0,i=0;
I was given the assignment of creating a number to word program for my first college java programming homework.
Here is what I have created so far :
import java.util.*; public class PrintNumberInWord { // saved as "PrintNumberInWord.java" public static void main(String[] args) { int number = 5; Scanner sc = new Scanner (System.in); { System.out.println ("Enter a number"); System.out.println(" "); if (number == 1) {

The first lines were made for us so we could follow a guideline, however, no matter what I type the command prompt displays 5 to me, I know thats because 5 is defined in the beginning but backspacing 5 causes the program not to work at all, how can I get this program to work properly?
any method or common algorithm to change a number taken from input to the word for that number? Such as input being "4", output would be "four", at least up to 59 as the larger program I'm trying to make involves time
i'm trying to do a program that memorizes the elements formed by a word and a number. For example, if I write ABB 3, AB 2, ABB -2, ABC 5, ZZ 2 the program will write:
ABB 1 (the result of abb (3-2)) ABC 5 AB 2 ZZ 2
Also, should write:
2 AB ZZ 5 ABC 1 ABB
I've tried to do it with a TreeMap but i don't know how it works.
I am having some trouble with this program. The assignment is to write a program, given a seven-digit phone number, uses a PrintStream object to write to a file every possible seven-letter word combination that corresponds to that number. I have to avoid using 0 or 1. Here is my code.
import java.io.FileOutputStream; import java.io.IOException; import java.io.PrintStream; import java.util.Scanner; public class TelephoneGenerator { String phoneNumber; char numberLetters[][] = {

I am getting an error dealing with the main class.
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;
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?

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.

Why don't the a's show up on the console? I put them in as part of the debugging process and now I don't understand why they don't show up in both places.

Ok, so I'm making a game with a space ship that flies around the universe and discovering new planets. It works fine so far, but I'm looking to make it perform better and be better compatible with lesser-processors.So, I'm trying to put in an FPS counter and an entirely new game loop so that my game can decide for me what FPS I should use.
I have two classes. Heres the big, main one: [Java] package cyentw.game.src; import java.awt.Color; import java.awt.Font; impor - Pastebin.com *I want to change the loop and put an FPS counter in around line 456, you can scroll past the rest if you'd like*And heres the init frame one, in case you'd like to see it for some reason.
Java Code:
package cyentw.game.src; import javax.swing.JFrame; public class Start extends JFrame{ public static JFrame frame; public static int WIDTH = 500; public static int HEIGHT = 500; public Start() {
[code]....
how to make my game loop as quickly (or a bit slower) as it can, and my FPS is static.
How do i make the 'date' column show only the date and 'timeIn' and 'timeOut' column only show the time. In my database table my 'date' column is a date type and 'timeIn' and 'timeOut' column is time.
I have a question related to the code below, that I do not understand. The aim is to count all files and subdirectories in an ArrayList full of files and subdirectories. So I have to count every file and every subdirectory.
The code concerning counting files is clear to me - every time d is of the type file I have to increment n by one. However I thought that I have to do the same thing in case d is a directory, so I would have written the same code for directories.
So what does "n += ((Directory) d).countAllFiles();" mean? In my understanding the method countAllFiles() is applied again on the object Directory ( as Directory is the class that contains this method), but how is n incremented by this? I thought n should be incremented by one as we did with files.
public int countAllFiles() { int n = 0; for(SystemFile d : content) { if(d instanceof File) { n++;
