The goal of this code was to create a program using main method java to analysis a piece text which has been entered from a user.
They do this by entering the text into a scanner which is then analysed by the program. The analysis is to produce word frequency, for example " This is a test" produces this results:
This is a test
1 letter words: 1
2 letter words: 1
3 letter words: 0
4 letter words: 2
5 letter words: 0
The bit that I'm stuck on is producing a mean/average, My mind telling to divide
counts.length
by
str.length
But I'm not the Best at java and I've tried to implement this but all I get are errors.
Code:
import java.util.Scanner;
public class While_Loop {
public static void main (String[] args) {
while(true){
I am looking for a way to create a method with the initial state in while loop, which will count the length of each word in a string using I want the output to be something along the lines of:
hello world how are you There are 0 words of length 0 There are 0 words of length 1 There are 0 words of length 2 There are 3 words of length 3 There are 0 words of length 4 There are 2 words of length 5
This is my code so far it sort of does the job but not the way i want it too
import java.util.Scanner; import java.util.StringTokenizer; public class Brown_Matthew_13117002{ public static int count(String s, int len){ int result=0; StringTokenizer st=new StringTokenizer(s,"[ ,;]");
[Code] ....
The output would end up being :
hello There are 0 words of length 0 world There are 0 words of length 1 how There are 0 words of length 2 are There are 3 words of length 3 you There are 0 words of length 4

I think I need to use string.split instead of stringtokenizer and the while loop is incorrect it needs to loop equal to the number of letters in the longest word. But how to do either of these ?
import java.awt.*; import java.applet.*; import java.awt.event.*; public class Assignment extends Applet implements ActionListener { TextArea textInput = new TextArea(); // user input Button analyzebutton = new Button("Analyze"); Button resetbutton = new Button("Reset"); Label lbloutput = new Label ("Please enter text into the textbox!");
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.

I'm trying to do the following and my code is putting me in a loop and not allowing me to input a valid entry after using an invalid #.I ask the user for input which contains a loop if the user doesnt use the correct information, however the loop doesnt allow the user to input if the entry fails the which statement

I have this code running correctly in Eclipse all except that it seems no matter where I declare, highest, lowest, average they always seem to stay at "0". I have a feeling the location of the Initialization is not the error since I have tried moving it to inside differ loops.
Stipulations on writing this code are:
Note: You do not need to use array to save each input score for this lab. A Single loop to read in each grade, compare with the current highest grade, lowest grade, and calculate the running sum at the same time.
import java.util.Scanner;
/*Write a program that prompts the user to enter the total number of students first. *Then ask the user to input each student’s grade and use loop statements to read in each grade. *Check input grade to make sure 0<=grade<=100, if the user input any other number, print out warning message and ask the user to input a new grade. Display the highest score, the lowest score and the average. */

How to use a constructor with parameters where the user inputs the information? I'm doing a problem where I create a Delivery class that accepts arguments for the year, delivery number within the year, distance code (1 for short distance, 2 for long), and weight of package. The constructor is supposed to also determine the eight digit delivery number (combining the year and delivery number, like 20140054 for this year, package #54).
I know I'm not close to being done but I'm struck on the application with the constructor parameters. If I'm asking the user to input the information, does that mean I have to create a no argument constructor so it will compile? Right now it won't compile because it's asking for the parameters but I can't put them.
This is the class:
public class Delivery { int year; int delNum; double weight; int code;
[Code] .....
And the error is:
CreateDelivery.java:22: error: constructor Delivery in class Delivery cannot be applied to given types; Delivery firstDelivery = new Delivery(); ^ required: int,int,int,double found: no arguments reason: actual and formal argument lists differ in length 1 error
I'm writing a temperature converter for class, and I'm done but one piece that I can't wrap my head around.My input scale radiobuttons work fine, but the output scale radiobuttons don't deselect automatically. They're two different button groups and I wrote them identical save for the variable names.
Total IS those numbers. But question[10] will not cooperate with me and it's getting a bit aggravating as I can't find a logical reason for it to be doing that.how to perhaps lock the value of total and sTotal after 10 button clicks from any?
Write a method called isSorted that accepts an array of real numbers as a parameter and returns true if the list is in sorted (nondecreasing) order and false otherwise. For example, if arrays named list1 and list2 store {16.1, 12.3,22.2, 14.4} and {1.5, 4.3, 7.0, 19.5, 25.1, 46.2} respectively, the calls is Sorted(list1) and isSorted(list2)should return false and true respectively. Assume the array has at least one element. A one-element array is considered to be sorted. public class thirfd {
I have spent some time thinking about the program, and realize I need two loops-- 1 that keeps track of bricks in a row and 1 that keeps track of the number of rows as the Pyramid rises in height. The Pyramid is supposed to be centered on the bottom of the screen. Three CONSTANTS have been required:
I tried breaking the scope of things down by trying step-wise refinement. But, I got bogged down. When I tried a method where both loops were included, I got limited success. For some reason, my equation to center along the x axis seems to be doubling the number of bricks. But, the correct number of total rows of bricks was a success. Also, the Pyramid was centered on the bottom of the screen. Another frustrating failure was that the number of bricks would not decrease as the new layers were created. My thought process was instead of using a loop that counts up (i++) I would use a loop that counts down (j--) which I thought would reduce the number of brick in each row as the "y" coordinate was reduced by each count of the BRICK_HEIGHT.
This is the code that "works". Whenever I add the (j--) the results are NOT what I expect.

my application (java 6 RedHat 5.3 x64 ) using clean content jar for extracting data from email messages with attachments (doc, xls, ptt ...etc) After update from CleanContent-2009.1.1.jar to CleanContent-2011.1.1.jar (and any newer version) CompilerThreads will stuck in some cases (pretty often) In that case CPU usage is 100% all time, even when all activities on application are finished.
I was able to isolate several messages and every time when I used CleanContent-2009.1.1.jar it works ok but always stuck with CleanContent-2011.1.1.jar or newer versions!
I think I'm about 90% complete with this program but I'm stuck on my adding entries method. It gives me a runtime error which says:

Basically I have a class called Book. Its supposed to have a few simple methods that set the title of the book, mark it as returned or borrowed. So specifically my problem lies in the implementation of the method that decides if the book isBorrowed. I was thinking i'd use a simple if/else statement but the way i've been trying hasn't been successful. This is what i've tried so far.
public class Book { String title; boolean borrowed; boolean returned; boolean isBorrowed; // Creates a new Book public Book(String bookTitle) {
The problem i believe is that I have the max value set to the first value given out, but every time the loop repeats the Max value gets reset to the next value in the file.
Essentially the program is supposed to read a list of credit card transactions and tell the user which transaction is the highest.
Here's the list of the sample file, note that the number of transactions could change that's why i haven't tried simply passing the values to method.
