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;

How To Make File Reader Object Move To Next Line If There Is No More Input On Line
Feb 18, 2015How do I make the file reader object move to the next line if there is no more input on the line. Here is my text and output file as you can see that my text file column cuts off on the 2nd line after 70. I want to read that next line which is 100 into my labs variable however its reading it into my final exams variable. I'll also post the code but I didn't think it was necessary.
textfile:
100908095
1008070
10070
output:
Labs Projects Tests Final Exams

1008070100
70

import java.io.*;
public class MyGrades
{
public static void main (String[] args) throws IOException
{
int lab, project, test;

I/O / Streams :: Reading A File Line By Line And Deleting It
Oct 15, 2014If I want to read my file line by line and when it hits a certain value from that point it should start deleting the lines until the tag ends.Just curious will my code actually work at the moment or not because it goes through so many times then goes straight back to the variable declarations at the start of the method and never hits the console print line.

Find A String And Display Line Number And Line Itself?
Oct 20, 2014I'm creating a program that searches a txt file for a given string, then return the number line and the line itself. However, my testFile class isn't detecting my searchWord methods.
The searchWord and recursiveSearch is written in a java class called BasicFile
public List<String> searchWord(String key) throws Exception {
LineNumberReader lnr = new LineNumberReader(new FileReader(f));
return recursiveSearch(lnr.readLine(), key, lnr);
}
public List<String> recursiveSearch(String currentLineText, String key, LineNumberReader lnr)

Is it because I'm using a list instead of a string?
Scanning Next Line Of Input Without Advancing Past Line
Apr 12, 2014I'm doing an assignment for uni and have come across a small hiccup. What I'm trying to do is scan in a text file and read "commands" for it line by line, E.g:
Student Mary 12345 19
Student Joe 12346 19
Change Joe 19 20
Change Mary 19 20
So that lines that begin with the word "Student" indicate that I should create a new student file with that name, student ID, and age.
"Change" indicates that I should be changing the specified student's current age to the new age etc.
What I'm currently doing is something along the lines of this:
Scanner input = new Scanner(new FileReader(args[0]));
String[] line;
while (input.nextLine().startsWith("Student")) {
line = input.nextLine().split("s+");
[Code] ....
The problem I'm having is that every second line seems to be getting skipped (because I'm calling nextLine() so much?) but I can't think of a way to "peek" at the first word of each line without advancing past it. Is there any way of doing this?
Read File Line By Line
Dec 8, 2014how to read file line by line ? Namely my input file I want to read look as follow:
AAA 1, 1
12 222 12
AAA 2, 2
11 122 11
My output file should look as follow:
1, 1, 12
1, 1 222
1, 1, 12
2, 2, 11
2, 2, 122
2, 2, 11
I think the lines need to be stored in ArrayList, then I would like those lines to write to csv file, but how on read I can construct such output file? This is my code for reading file

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane
Dec 12, 2014I am checking how to do following task.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?
Comparing Two Variables
Mar 30, 2014Let's get it out of the way -- I'm stumped. On something that should be pretty simple to solve. Code follows.
public class Sum {
public static void main(String [] args) {
Double nSum = 0.0;
Double aDouble = 100.0;
for (int i = 0; i < 1000; i++){
nSum += 0.1;
[Code] ....
The output:
100.000000
100.000000
false
false
false
false
false
Process finished with exit code 0
I wrote another simple program and hardcoded the values: aDouble = 100.0; bDouble= 100.0000
Using aDouble.equals(bDouble) returns true, just as one would expect.
So what am I overlooking?
Comparing Two Hashmaps
Mar 3, 2015I have a simple question but I dont understand why I am getting false for this boolean statement.
System.out.println("hash compare " + (trialSearch.returnHash() == fish.returnHash()));
System.out.println("fish.returnHash()" + (fish.returnHash()));
System.out.println("trialSearch.returnHash()" + (trialSearch.returnHash()));
the output is as follow:
hash compare false
fish.returnHash(){T=[1, 2, 3, 5], G=[], A=[0], C=[4]}
trialSearch.returnHash(){T=[1, 2, 3, 5], G=[], A=[0], C=[4]}
why is it printing false for the boolean statment when the two hashmaps contain the same values and keys?
Comparing First Name Of Two People

View Replies View RelatedComparing 2 String Values?
Nov 8, 2014I am trying some exercises on codingbat.com, and am stuck at the following program.
"Given a string, return true if it ends in "ly"."
With the following lines, if I type a print command instead of return, I get "ly". Yet if I aks to compare the result (which is "ly" as I can see with a print command) with == "ly", I get false?
What I also don't get, is that if I tye the programs in javascript, in that language the program works.
String str = "Oddly"
return ((str.substring(str.length()-2))== "ly");
}
Comparing And Cloning Objects?
Aug 2, 2014I'm working on a program with the following instructions: Write a class named Octagon that extends GeometricObject and implements the Comparable and Cloneable interfaces. Assume that all 8 sides of the octagon are of equal size. The area can be computed using the following formula
area = (2 + 4/square root of 2) * side * side
Write a program (driver) to read in a series of values from a file, display the area and perimeter, create a clone and compare the object and its clone (based on the area). In addition, your program should compare the current object (just read in) with the first object read in. The program ends when a negative number is read from the file.
My GeometricObject abstract class:
public abstract class GeometricObject {
public abstract double getArea();
public abstract double getPerimeter();
}
My Octagon Class:
public class Octagon extends GeometricObject implements Comparable<Octagon> {
private double side = 1.0;
protected native Object clone() throws CloneNotSupportedException;
public Octagon() {
}
public Octagon(double side) {
super();
[code]....
As you can tell, I've still got a long way to go in the tester class but this is where I'm running into some difficulties.
You'll notice that in the return statement of the toString method in the Octagon class, I put a ? after the "Clone Compare:" portion of the code, what should go here. I've never worked with either the Comparable or Cloneable interfaces before.
How I should create my objects in a way that would give the following sample output.
Object 1: Area: 120.71
Perimeter: 40.0
Clone Compare: Equal
First Compare: Equal
Object 2: Area: 271.60
Perimeter: 60.0
Clone Compare: Equal
First Compare: First is smaller
Error Comparing Strings
May 24, 2014I was writing a code to have the library books classified in name, author, area, ed, etc. I'm using NetBeans and it doesn't accuse any error. But when I run the project, it never goes right and shows the books only in one area, regarthless what I type. (The goal of the algorithm is to separate the books in areas (sciences, humanities and biological science).

Apr 20, 2014Ok I am trying to compare a string to see if all characters are unique. If there is a library for this or a better way to approach this do tell.

Comparing Two Arrays With Same Size
May 7, 2013Is it possible to compare 2 arrays as below if they have same size?
Int array[][] = new int[10][10];
array1[I] == array2;
Or assign the whole array to another array?
array1[I] = array2[I];
Suppose I have 2 arrays, 1 is old, and 1 is new.
I will do the calculation to update the new array.
Then, I will compare between the 2 arrays.
If they are the same, I will stop the calculation.
If they are not the same, I will assign the new array to the old array.
Then, I will do the calculation again until the old array and the new array are the same.
As I do not want to write a loop to compare and assign the value to the arrays. May I compare or assign the values to the whole array directly.

Comparing Specific Elements Of Two Arrays
May 5, 2015I’ve been working on this problem for a couple days already but I came to a point where I don’t really know what to do. Basically I’ve got two arrays filled with int values (0, 1, and 2), which I get from Class B through their respective getMethods.
1 stands for black and 2 stands for something else.
The program counts how many times the value 1 (if chosen color is black) occurs in both arrays and then compares the both counts. If it detects any difference the program does something else, otherwise it waits.
public class A {
private static boolean finished;
public A() {
B objectClassB = new B();
int[] numbers = objectClassB.getNumbers();
int[] numbers2 = objectClassB.getNumbers2();
String color = objectClassB.getColor();
[Code] ....
Here the class B.
public class B {
private int[] numbers = new int[] { 2, 2, 0, 2, 1, 0, 1, 2, 1, 1, 0, 2, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 2, 1 };
private int[] numbers2 = new int[] { 2, 2, 0, 2, 1, 0, 1, 2, 1, 1, 0, 2, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 2, 0 };
private String color = "black";
public B() {
}
public int[] getNumbers(){
[Code] .....
this would be the Output:
[2, 2, 0, 2, 1, 0, 1, 2, 1, 1, 0, 2, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 2, 1]
[2, 2, 0, 2, 1, 0, 1, 2, 1, 1, 0, 2, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 2, 0]
number of black tokens of first array: 8
number of black tokens of second array: 7
the number of black tokens has changed
The actual problem is that I will be getting one array at a time (meaning: the array int[] numbers from Class B updates itself and might change its values). I just declared and initialize both arrays for illustration purposes.
That would mean I need to hold the array’s values the first time I get them in a temporary variable until I get the values of the updated array. Then I could use them in the method –numberOfRelevantElements- and check if any changes have occurred.
What would be the best approach for doing this? I though of inserting the different counts that I get into a queue and then comparing these values one after the other. But I’m not really sure if that would work.
