I want to write an application that inputs a sentence, tokenizes the words with method split and reverse the words (not the letters)...I am stuck at the last part: how to reverse them...should I use the method reverse(); ?
Here is my code..
import java.util.Scanner;
import java.util.StringTokenizer;
public class ReversedWords {
//execute application
public static void main( String [] args) {
//get sentence
[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;

Write a program to reverse each word in line(sentence)?
View Replies View RelatedI 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" };

This is a program to input a sentence and print the words that start with a vowel.......There is no syntax error but on executing and typing the sentence and pressing enter,I get a error saying :
java.lang.StringIndexOutOfBoundsException: String index out of range: 0
at java.lang.String.charAt(String.java:658)
at sentence.main(sentence.java:22)
[Code] ....
You 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

I want to know how the for loop works for the column?
This is what I have to do:Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.
Example:
"George Washington"
"Washington, George"
I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value.
import java.util.*;
import java.util.Scanner;
public class Test {
public static void main ( String [] args ) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter name: ");
String name = sc.nextLine();
String lastname = "";
String firstname = "";
for(int i = 0; i < name.length(); i++) {
if(name.charAt(i) == ' ')
I'm trying to make this code's output display like a sentence, since right now it displays downward and doesn' look right.
public class ReverseOrder {
public static void main(String[] args) {
String phrase = "The rain in Spain falls mainly on the Plain";
char[] phraseArray;
phraseArray = phrase.toCharArray();
for(int i = phraseArray.length - 1; i >= 0; i--){
System.out.println(phraseArray[i]);
}
} // end main
} // end ReverseOrder class
Below codes find the character frquency how to print this in reverse order using comparator or else
public static void main(String arr[]) {
String s="bebeao";
Map<Character,Integer> chars=new TreeMap<Character,Integer>();
for(int i=0;i<s.length();i++) {
char x=s.charAt(i);
Integer count=chars.get(x);
if(count==null)

I have to write a program that takes an order of numbers and print the reverse order of those numbers.

I have a college question ask me to write a class StringRevert which does the following:
-prompting user for an interger n
-creating an array of n string
-repeatedly read character string from user input and store them in the array until end of array is reached or user input -quit(quit should not saved in array)
-print the string from array in reverse order, from last enter to first enter.
-assume user always supplie correct input
This is what I've done so far but how to get it working.
import java.util.Scanner;
public class StringRevert {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("enter value of n: ");
int n1 = in.nextInt();
String[] n = new String[n1];

I have the following double linked list and I'm supposed to order it descending (reverse) using the printInReverse() method; since the list orders itself ascending when the numbers are added, how could I order it descending in this method? Here's the code without implementing descending/reversing methods:
package test;
import java.util.Scanner;
public class MyList {
private Scanner userInput;
private Integer selectedOption;
private MyListElement firstElement = null;
private boolean exitRequested = false;
[Code] ....
I tried to declare a previousElement variable but I didn't figure out how I'd do that.
Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.
- You should ask the user to enter the full path to your file to make certain you are processing the correct file.
- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.
Hint: read the content of the file into an ArrayList and then traverse the ArrayList.
this is what i go so far.
package classActivity;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;
public class Select

Write a Java program that asks the user to store 10 numbers in an array. You should then print the array in the order entered and then print in reverse order. However, instead of putting all the information in the main, you should use a class called PrintIt. The PrintIt class should have an instance variable that is an array to hold the numbers. You should have a method that will print the array in the order entered. You will also need a method to print in reverse oder. Then create a tester class that asks the user to enter 10 numbers and puts them in an array.
So far I've got this.
public class printIt {
int i;
int [] numArr = new int [10];
public printIt () {
i = -1;
[Code] .....
Output:
Enter a number:
8
34
Forward:
8
34
Reverse:
34
8
end
what i want as an number is being able to print out 10 numbers but this only lets me do two numbers. Why is that so?
I am trying to do this assignment but I can't get the needed output.

And how the comparator used in this example is sorting elements in reverse order
One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
Any link to the accurate explanation of binary trees in java?
