Convert Numbers From -999 To 999 In Words
May 19, 2014I'm very new to Java and need to write a program where the user inputs any number from -999 to 999 and it inputs it in words. For ex -24 entered would print negative twenty four or 800 entered would be eight hundred. I need to have at least 2 methods that need to be returned to the main method. When i compile, it says that cannot convert from void to java.lang.string for all the word = ... in my case statements.
import java.util.Scanner;
public class NumToText {
public static void main (String args[]){
Scanner input = new Scanner (System.in) ;
System.out.println ("Enter number.");
int number = input.nextInt ();

Program That Accept Words And Their Meanings Or Display List Of Words In Lexicographical Order
Apr 15, 2015Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. Another requirement - from time to time words become obsolete. When this happens, such word must be removed from the dictionary.
Use the JOptionPane class to enter the information.
Use the concept of linked list to carryout this exercise. You will need at minimum the following classes:
- A WordMeaning class that hold the name of a word and its meaning.
- A WordMeaningNode class that creates the node of information and its link field.
- A WordList class that creates and maintain a linked list of words and their meanings.
- A Dictionary class that test your classes.
For the output, the program should produce two scrollable lists:
- The current list of words and their meanings.
- The list of the deleted words. You need not list the meanings, just the words.
So far, I have everything coded except for the remove method, and I am not sure how to code that. I coded the add method already, but now I don't know where to begin with the remove method in my WordList class. My classes are below.
WordMeaning Class:
public class WordMeaning {
String name;
String definition;
WordMeaning(String t, String d) {
name = t;
definition = d;

Long Type Output File - Print Prime Numbers Between Given Range Of Numbers
Aug 22, 2014I tried to create file and write the output of my program in it in java when i use WriteLong then the file does not contain long value, how I create this file my program is to print prime numbers between 500000 to 10000000
public class primenumber {
public static void main(String[] args) {
long start = 5000000;
long end = 10000000;
System.out.println("List of prime numbers between " + start + " and " + end);
for (long i = start; i <= end; i++) {
if (isPrime(i)) {
System.out.println(i);

Generate 100 Numbers Using Arrays - Sort Even Numbers Into Separate Array And Display Both
Apr 24, 2014I've just written a program that generates 100 numbers that range from 0 ~ 25 using arrays, the program calls another method that sorts the even numbers into a separate array and returns the array. I need it to display both arrays, however, when I run my program, the numbers of both arrays are mixed together, and I'm not sure how to separate them.
[ public class Array1
{
public static void main(String[] args)
{
int array [ ] = new int[100];
for (int i = 0; i < array.length; i++)
{
array[i] = (int) (Math.random() * 26);

Print 2 Lists - 20 Random Numbers And Another List Without Duplicate Numbers
Feb 1, 2015I'm trying to make a program that generates 20 random integers between 1 and 20 and then prints the list of random numbers to the screen. After that, I want to print a different list to screen with the same numbers from the first list only skipping any number that has been already printed to the screen. So two lists are printed to the screen. The first one has 20 random numbers. The second one has those same 20 numbers but only prints the numbers in the first list that aren't duplicated. So if m
y list of 20 random integers contains three 2s and two 14s, only one 14 and one 2 is printed to the second list. Currently, my code generates 20 numbers from 1 to 20 and stores those numbers in an array but I don't know how to print solve the second part of my problem. I don't know how to print the s different list only without duplicate numbers. As a result, my output is nothing because it doesn't print any number from the first list as oppose to skipping only duplicate one.
public void randomNum(){
System.out.println("Twenty random integers: ");
int max = 20; // max value for range
int min = 1; // min value for range
Random rand = new Random();
int[] all = new int[20];

Create Non Repeated Words
Jun 21, 2014I wrote a code for a "skydiving" program that randomly selects the "maneuvers" to be performed by the skydiver during his skydive. I am almost done with the program. I just need to figure out how to print non repeated maneuvers for each round. Each round may not consist of two of the same maneuvers. The program that I wrote randomly picks the maneuvers but sometimes it still prints out two of the same maneuvers for each round.The following is my code.
import java.util.Scanner;

Amending Whole Words To Char
Apr 15, 2014So my goal is to build a word search here. The road block I have run into is how to save words, input from user, into an array. Then once I figure that out I need to try and arrange them in such a way so that they will fit into my array without screwing with one another. It does not have to be working exceedingly well I mean really it can be assumed that the users will not try to screw the program up. Ie one or two words and a fairly large table will be all the input. Here is the program as of now:
import java.util.Random;
import java.util.Scanner;
public class BuildWS
{
int r;
int c;
char[][] array;
String query = " ";

Generate Two Arrays - One With All Positive Numbers And Another With Negative Numbers
Mar 10, 2015Create an integer array with 10 numbers, initialize the array to make sure there are both positive and negative integers. Write a program to generate two arrays out of the original array, one array with all positive numbers and another one with all negative numbers. Print out the number of elements and the detailed elements in each array.
public class problem3 {
public static void main(String[]args){
int[] numbers = {1, 2, 3, 4, 5, -1, -2, -3, -4, -5};
for (int i = 0; i<numbers.length;){

Program To Find Repeated Words
Feb 5, 2014I have made a program which finds the number of occurrence of the words. It is as follows :
public class B {
public static void main(String[] args) {
Map<String, Integer> mp = new LinkedHashMap<String, Integer>();
String s = "This is me tarun ohri This";
Scanner p = new Scanner(s);
int i = 0;
[Code] .....
Output is coming {This=0, is=1, me=1, tarun=1, ohri=1}
Using Min-heap To Sort List Of Words
May 5, 2015I am learning to use heaps and as an exercise I am trying to write a program using a heap class I have created to sort words. I have read in words from a file and added them to the heap successfully. I am having some trouble figuring out how I can print out a sorted list of the words. From my understanding of how a min-heap works, if I remove from the min/root node they will always be removed in sorted order. So far I have tried out to do a simple for loop but, only half of the heap is being removed. Not sure if my logic is incorrect of there is an error somewhere in my removeMin() function specifically in the while loop.
public static void main(String[] args) {
Heap heap = new Heap();
heap = read( heap );
for( int i = 0; i < heap.getSize(); i++){
heap.removeMin();

Using String Methods To Count Words?
Nov 3, 2014Aeparated by blanks in a string. For simplicity, use strings without punctuation or other white space characters(tabs, newlines etc). Use a JTextArea to allow the user to enter the text and allow the text area to scroll if necessary. when the user clicks a button to count the words , the total number of words counted is displayed in a textbox that cannot be modified by the user.
now my problem is that i am not getting the counted number to display in the un-editable textbox. i also have the problem where the cusrsor is showing in the middle of the input screen instead of at the top.
import java.io.*;
import java.awt.*;
import java.awt.event.*;

Extract Digits From Between Words Deal And Of
Mar 15, 2015What I am trying to do is extract the digits from between the words 'deal' and 'of'. I was wondering if this was possible to do with a regular expression or if I should just use a scanner.
UNIQUE Passive - Cleave: Basic attacks deal 20% to 60% of total Attack Damage as bonus physical damage to enemies near the target on hit (enemies closest to the target take the most damage).
Is there a regular expression that I could use in order to extract the '20' and the '60' from the above text. Below is what I have tried, but does not work.
(?<=deals)(d+(?=%))(?=of)
just to make a clarification, these numbers will not be the only numbers and the strings themselves will change. Everything can be considered a variable. The only constants between each string would be the words 'deal' and 'of'. The regex pattern "d+" is not a viable expression for my case

String Of Words - Getting First Letter From Each Word?
Mar 26, 2014If I have a string of words and want to get a letter from each word (let's say the first), how do I code for anything past two?
For example, if I have North Atlantic Treaty Organization and I want to convert it to NATO I would do something like:
charAt(0) for N
charAt(x + 1) for A
But what do I do for anything past the second string? If I do charAt(x ++ 1) I get an error.
Delimiter Function And Number Of Words In String
Apr 20, 2014Working on my java skills. The is Delimiter function is suppose to return true if there is a delimiter in the string and false otherwise. The main is suppose to call this function and count the number of words in the string:
Here is what I came up with:
import java.util.*;
public class NumberOfWordsInString {
public static void main (String[] args){
Scanner in= new Scanner (System.in);
String s;
[Code] ....
Somehow my method isn't being successfully called by my main and the following error msg was received:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
length cannot be resolved or is not a field
The method isDelimiter(char) in the type NumberOfWordsInString is not applicable for the arguments (char[])
at javaimprovements.NumberOfWordsInString.main(Number OfWordsInString.java:10)
line 10:
char ch [] = new char [s.length];
and the main doesn't call the isDelimiter function
Counting Number Of Words From User Input
Jan 2, 2015I tried the following code, OK:
Java Code:
String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
However, when i get the input from user , i didnt get the expected result:
Java Code:
System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
Now Result for above code:
Enter the string to count the words:
hi this is new
words are: 1
Reads Text File Consisting Of Words From A To Z
Apr 12, 2015I am writing a program for my college class that does the following:
Reads a text file that consists of words from a-z. The content read from the file is displayed in the JTextArea, while the user can filter the search results based on what they input. For example, if the user enter's "a" then the JTextArea is updated with all words that start with the letter "a" only. Also the user can enter a substring or the whole word and the respective result will be only the words that match the user's input.
The Problem and question I have is what would be the best way to go about filtering a file of about 27,000 words based on user input. I tried using an arraylist but the problem is it took forever to update the JTextArea, which is not good. Also I am new to using JSwing so I may not be aware of a component that would make this easier.
Here is the code:
