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}
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;

I/O Streams :: Insert Space At Proper Place By Breaking Sentence Into Correct Words
Nov 27, 2014You are given 2 files - "testcase.txt" and "validwords.txt".In testcase.txt, the sentences are written without any space inbetween/for ex: this is a sentence which looks ambigous.You are to insert a space at the proper place by breaking the sentence into correct words, ex o/p: this is a sentence which looks ambigous.validwords.txt contains all valid words (as 1 word per line). If you find a word that does not match, replace it with ####. After correcting

Oct 5, 2014Requirements - Use only standard Java API and no apache file utils for this.
Most of the answers I found on the internet either dont meet this requirement or load all file names into an array which can consume too much memory when no. of files = 20,000+. how I can do this. Is there also a way to keep track of new files that were added during the execution of the loop in this code ?

View Replies View RelatedCounting 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
Identifying Difference Between Integers And Words From User Input
Feb 24, 2015I am currently taking a computer science class in high school, and its my first time programming (2 weeks since i started). I have currently finished my program however there were a few details that bothered me. I was supposed to create a program which can calculate average of individual marks and then calculate all of the average marks previously entered by user. However I noticed something that bothered me, which was the fact that if i were to enter a number when asked to enter a name, it would assume that number is a name. Also when I asked for the 5 marks the program would run fine until an error occurs if i accidentally type in a letter or word. I have done some research and found system scanners however i still don't understand the concept in a looping situation. Here is what I have so far.
import java.io.*;
public class loopingEx6Final {
public static void main(String args[]) throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
double average, totalaverage = 0;
int Mark, Marktotal=0, marktotalsum=0, count=0;

Sort User Input 3 Words Alphabetically And Output Middle Word
Feb 8, 2014I have a project requiring me to build a program having a user input 3 words, sort them alphabetically and output the middle word.

How To Find Directories Of The Files
Jan 22, 2014How to find the directories of the files. Unfortunately, I have not been able to grasp the concept behind this idea. If I find to see if a particular file is there, can I not go to the file directly rather then having to use CMD (command). What is the purpose of CMD?
Secondly, I took a c++ class and now I'm in my second course which is integration the materials from c++ in to java. We are learning about classes. I have not been able to understand what classes do for you...and I noticed that in c++ (visual studio) the main started like Java Code: int_tmain(...) mh_sh_highlight_all('java'); but the topic we covered yesterday started like Java Code:
public class helloworld
{
public class helloworld(String)
{}
} mh_sh_highlight_all('java');
How To Find Files In Given Directory

View Replies View RelatedRead Input File And Create Output With Anagram For Words In File
Sep 24, 2014Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!
Heres is the code:
import java.io.*;
import java.lang.*;
import java.util.*;
/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.

Create Program That Prompts Input And Creates File With That Input As Name
Jul 14, 2014So I was going to try to create a program that prompts input and creates a file (That didn't exist before) with that input as name.Then, the program prompts inputs after stating questions such as 1 + 1, then if the user inputs an answer, put "Question # = Correct "or" Wrong.Code SO Far:
Java Code:
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
public class File_Read {
public File_Read() {//File_Read is the Interactive object
[code]....
So that it puts the Correct or Wrong into the file.

User To Input 10 Numbers - Find Smallest Element In Array
Dec 2, 2014I am trying to write a code that asks the user to input ten numbers and then finds and displays the smallest number out of the ones given. I am supposed to implement arrays into the program to do this. But the problem I have run into is that when I compile the code in jgrasp, I am given several error messages and I am not quite sure what I have done wrong. I'm assuming it is either a syntax or a logical error on my part but reading over the code I do not understand what is causing these errors.
This is the most current draft of my code:
import java.util.Scanner;
public class Exercise7_9 {
public static void main(String[] args) {
double[] numbers = new double[10];
//Enter ten double numbers: Scanner(System.in)
java.util.Scanner input = new java.util.Scanner(System.in);
System.out.println("Please enter ten numbers: ");
[Code] ....
/* Sample Run:
Enter ten numbers: 1.9, 2.5, 3.7, 2, 1.5, 6, 3, 4, 5, 2

And these are the exact error messages:
