Accept A String And Display All Palindrome Words
Jan 23, 2015
The program is to accept a string and display all the palindrome words(the words that are same even if they are reversed-------->mom,madam,malayalam etc.)in the string.
I need to solve this program urgently.
There are no syntax errors but after typing in the sentence,no output is displayed. This is my program....
import java.util.*;
class palindrome_test
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
System.out.println("Enter a sentence");
String usersInput=in.nextLine();
[Code] .....

Write 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;

This program is supposed to accept an integer as an input and display the message that the number is even or odd. The main method calls a Boolean method. Write a method private static boolean iseven(int number and the message is printed from the Main method. This is what I have.
import java.util.Scanner;
public class OddorEven {
int number;
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
[Code] ....
I know the message is not being printed from the Main method. I'm not sure how to do that.

I'm supposed to use stacks (implemented with an array) to check to see if a string is a palindrome. I've finished all my classes and methods, but I'm getting an ArrayIndexOutOfBoundsException when I try to run my demo program.Here are my classes:
public interface Stack {
// Creates an empty stack
public void initializeStack()
// Returns true if the stack is empty, returns false otherwise
public boolean isEmpty();
// The stack can never be full, so always return false
public boolean isFullStack();

I have to write a program that inputs a string and tests whether or not it is a palindrome. This worked fine, and now I want to make it so I continually enter strings until I tell the program to stop.
The code below compiles just fine, but it doesn't do what I want. Why it doesn't work how I think it should work? (Typing in STOP does not make the program stop.)
Here is the code
import javax.swing.JOptionPane;
public class PalTest {
public static void main(String[] args){
String S="pony";
while(S!="STOP"){
S=JOptionPane.showInputDialog("Enter a string (STOP to terminate):");
[Code] ....

I'm having a hard time with this problem, this is what I have, but I can not use two integers, I have to use one integer and a string...
This is the question:
Write a method called printStrings that accepts a String and a number of repetitions as parameters and prints that String the given number of times. For example, the call:
printStrings("abc", 5);
will print the following output: abcabcabcabcabc
This is what I attempted:
public class printStringsproject {
public static void printStrings(int abc, int number) {
for (int i = 1; i <= number; i++) {
System.out.print("abc");
}
}
public static void main(String[] args) {
printStrings(1, 5);
}
}

So currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?
Also here is an example of what I am trying to do, along with comments:
Java Code:
console.setText("Math is good!");
console.setText("What is 2+2?: "); //using getText gets the whole line, I want
//everything checked after the colon. That is where the input will be
if(line==4){
console.setText("That is correct");
}
else {
console.setText("That is incorrect");
}
//previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the
//whole JtextArea mh_sh_highlight_all('java');
A JtextArea is just not getting the job done.

I wrote a couple classes and am trying a test driver but it is having an error I do not know how to solve.
Student Class:
public class Student{
private Course[] courseList;
private static int numCourses;
private final int maxCourses;
public Student(int max){
maxCourses = max;
[Code] .....
Error:
javac tester.java
tester.java:6: error: cannot find symbol
one = new Course(name);
^
symbol: variable name
location: class tester
1 error
Same issue, just only one error as there is only one line. It seems like it does not accept my parameters as it cannot find symbol.
I forgot to put the "" in the brackets, it's been a month since I have looked at any java and made this simple mistake.

Aeparated 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.awt.event.*;

If 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.

Working 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

I am not very comfortable with Strings in Java. The problem I am facing is, taking a string that contains a sentence and reversing the words. Example would be, "Hi I am Bob" and changing it to "Bob am I Hi". Then returning the String.
My initial thoughts were to change the string into a character array and then manually doing the work with loops and tedious comparison statements. I quickly realized that there must be a better way but I am not very familiar with strings in Java to know what a more sufficient way would be.

Basically the requirements are to take a sentence (string of text) and check to see how many times specific words come up and then add to the counter depending on the word.
But I can not seem to get it to add the instances of the goodwords and badwords.
package Strings;
import java.io.*;
public class SentimentAnalyser {
private static String analyse(String text) {
int pw = 0;
int nw = 0;
String[] searchword = { "bad", "terrible", "good", "awesome" };
[Code] ....
