String Analyze - Take A Sentence And Check How Many Times Specific Words Come Up

Sep 8, 2014

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" };

Taking String That Contain Sentence And Reversing The Words

Sep 5, 2014

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.

Check How Many Times Char Is Used In The String

Apr 1, 2014

I tried to make a program that takes a string str, and char a and checks how many times the char is used in the string.

Example: the string Welcome and the letter e, is 2 times. so the program should print 2.

It compiles but when I run it and enter the information, i cannot get the printing line out.

Heres my code:

import java.util.Scanner;
class program
{
public static void main(String[] args) {
Scanner user_input=new Scanner(System.in);
String str;
String b;
System.out.print("Please enter a word");

Check Specific Value From A Specific Line From TXT File

Feb 8, 2015

I have some problem to understand the way to make this:

In my main class a user can save his name in a txt file (and the system initially will add 6 value equals to 0) than he can choose between 6 level and make it.

example of .txt file data:

mario 0 0 0 0 0 0
carl 0 0 0 0 0 0

AT THIS MOMENT i just made other class and they work, is this new one that is hard for me. I'm trying to make a class that:

1- (first method called verificaRisultati) take name_used and level_choosed from the main and go to check in the .txt file if that level before was done right(1) or wrong(0)

and return something like "before you made this level properly" or "before you made this level incorrectly" AND THEN let the user start with the level.

2- (second method called salvaRisultati) at the end of the level i wanna pass the result (correct/incorrect) to another method of this class that will save the value (1 or 0) associated to the user in the right position.

This is the class that i'm writing:

Java Code:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
public class ResultUsers {

[Code] ....

I really need some hint and some code example because I'm stuck. How I can take exactly the line with the user name? How I can correctly split the line in an array and then read/modify the value for that level?

Possible To Check If Classes Contains A Specific Method And Then Run That Method?

Oct 5, 2014

I'm working on a simple 2D Game Framework. Currently it's creating a window, but I'm working on an update method.

I constantly export the framework as a .jar file, and I've added it to the game's build path (using eclipse). I wonder if I can check all classes in the game-project (the project in which I've refecrenced the Framework in) for a specific method (for example update()) and call all found methods with that name from the framework's main class, like this:

public class FrameworkClass1 {
  private void checkForUpdateMethods() {
// Check for update methods on program start
} public void update() {
runAllFoundUpdateMethods(); // Run all update methods found in the scan
}
}

I want to do this because it would be a simple way to update and render the game. If the main game-class look something like this:

public class Game {
public void update() {
// Update the game every time this is ran
}
}

it will be automatically updated, because it contains a method named update(), instead of naming the main game-class with a specific name etc. It will simply be more flexible that way!

How To Print String Only Five Times

Accept String And Number Of Repetitions As Parameters And Print String Given Number Of Times

Oct 3, 2014

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);
}
}

Using String Methods To Count Words?

Nov 3, 2014

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.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.*;
import java.util.*;
public class WordCounter extends JFrame implements ActionListener

String Of Words - Getting First Letter From Each Word?

Mar 26, 2014

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.

Delimiter Function And Number Of Words In String

Apr 20, 2014

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

String Characters Display First Three Multiple Times

Sep 26, 2014

I am trying below challenge to display first three characters three times if the size of the string is greater than 3.

Say if i send hello i should get helhelhel

if i send xyz i should get xyzxyzxyz

I wrote as below

public String front3(String str) {
if(str.length()==3){
return str+str+str;
}
if(str.length()>3){
String str2=new String(new char[]{str.charAt(0),str.charAt(1),str.charAt(2)});
return str2;
}
}

I am getting error as below

Error:public String front3(String str) {
^^^^^^^^^^^^^^^^^^
This method must return a result of type String

Possible problem: the if-statement structure may theoretically allow a run to reach the end of the method without calling return. Consider adding a last line in the method return some_value; so a value is always returned.

Program That Accept Words And Their Meanings Or Display List Of Words In Lexicographical Order

Apr 15, 2015

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;

Count And Display Number Of Times Specified Character Appears In String

Mar 7, 2014

Write a program using a while-loop (and a for-loop) that asks the user to enter a string, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the string. (So, you will have two separate program codes, one using a while-loop and the other one using a for-loop.)

Example:
Enter a string: "Hello, JAVA is my favorite programming language."
Enter a character: e
The number of times the specified character appears in the string: 3

I don't even know where to begin I've only got this

import java.util.Scanner;
 public class letterCounter {
 public static void main(String [] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a string");
String myString = sc.nextLine();
System.out.println("Enter a letter");
String letter = sc.nextLine();
}
}

Array Setup - Analyze By Adding Up Contents Of Each Column

Feb 16, 2015

I've setup an array that I would like to analyze by adding up the contents of each column, however, the out of bounds exception pops up when I try to execute the program. I know the book usually expresses this operation the other way around, where the row is the argument of the first for statement, but I've set my array up where I need to add each row before moving to the next column.

vowelCounter is a 5x3 array.

// Display the line which had the most number of vowels

public static int maxVowelSentence() {
int max = 0, sum = 0;
int sentence = 1;
for (int row = 0; row < vowelCounter.length; row++) {
max = vowelCounter[row][0];

Running Java Application - Analyze Traffic Condition

Jun 18, 2014

I have a java application which uses Google Maps to analyze the traffic condition. But sometimes it can be run and work properly, sometimes not. On some computers on which there is installed java, the program can be run, and on some, again with installed java (jre), exactly the same version, the program can not be run. For example the application first run well on my desktop computer, connected in a LAN, and then stopped working well when run. But when I use laptop which uses the WiFi and run the same computer using VMWare, if I connect to the desktop on which the program can not be run, on the laptop the same program can be run well, in the same room, but using the Wifi.

How To Check If At Least One Number In A String Is Different From 0

Nov 18, 2014

I'm trying to come up with a method that would validate each turn a player makes. For a turn to be valid, it has to only contain numbers from 0 to 3(inclusive) and at least one digit must not be 0. Here is what I`ve come up with so far. For example, with "303" as the number and "101" as the turn, the turn would be valid and my method should return true, but it does not.

public static boolean turnIsValid (String number, String turn ){
boolean rep=false;
int pos1=0;
char min='0';
char max='3';

I'm trying to get the code right first, and then write a function for it.I basically just thought that I would iterate over the first string, and once I had the first character, I would then iterate over the second string, to see if the character exists. I'm getting a "dead code" error on my second loop because I put the second "break."
