I have this source code that is supposed to count the repeated occurrences of certain strings in the text file, "string.txt". The contents of the file are listed below:

AA-AB-AC-AG-AE-AL
AL-AQ-AE-AN-AO-AM
AM-AQ-AO-AA-AB-AC
AD-AJ-AK-AI-AM-AO
AN-AH-AC-AA-AP-AQ
AP-AP-AN-AN-AL-AP
AN-AD-AU-AE-AH-AQ

Counter To Count Random Occurrence

Jan 21, 2015

I have 2 classes a main one and another class. In the other class I have a method that has:

String gInfo(){
String[] Behavior = {"Sleeping", "Running home", "Studying", "playing pool", "walking to class"};
int rNum = (int) (Math.random() * Behavior.length);
return Behavior[rNum];
}

I call the gInfo() in the main class and run it through a loop 20 times. What I'm trying to do is get it to count the number of times that each behavior happens. and how to get it to work correctly.

JavaFX 2.0 :: Combobox - Visible Count Row Not Applied And Doesn't Change

Oct 15, 2014

I have noticed a strange behavior of Combobox element. The number of visible rows is not the same established by setVisibleRowCount() method. It happens when changing the items list dynamically. The following example reproduces it. I think it is Javafx 8 bug. I have tried unsuccessfully to trigger some event indirectly to refresh the combobox drop down.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.HBox;

Count Vowels In ArrayList Of Strings - N Cannot Be Resolved To A Variable

What I'm trying to do here is to count the vowels in an arraylist of strings. What I did may not be right, but that's not my problem for now. My problem is that i cannot return the value (n) I want to return. I don't know why.

public class One {

Uppercase Character Counter In A String

Jun 11, 2014

I have to create a code that can calculate the number of upper case letters in a string that is entered by the user (below.)

Java Code:

import javax.swing.JOptionPane;
public class mainClass {
public static void main (String [] args) {
String userInput;
userInput = JOptionPane.showInputDialog("Enter a string.");

[Code] ....

My issue is that I would like the program to be able to function properly when spaces are entered into the string. As it is right now, I believe it is only processing the first string entered into the input box.

Count Length Of Each Word In A String

Aug 5, 2014

I am looking for a way to create a method with the initial state in while loop, which will count the length of each word in a string using I want the output to be something along the lines of:

hello world how are you
There are 0 words of length 0
There are 0 words of length 1
There are 0 words of length 2
There are 3 words of length 3
There are 0 words of length 4
There are 2 words of length 5

This is my code so far it sort of does the job but not the way i want it too

import java.util.Scanner;
import java.util.StringTokenizer;
public class Brown_Matthew_13117002{
public static int count(String s, int len){
int result=0;
StringTokenizer st=new StringTokenizer(s,"[ ,;]");

[Code] ....

The output would end up being :

hello
There are 0 words of length 0
world
There are 0 words of length 1
how
There are 0 words of length 2
are
There are 3 words of length 3
you
There are 0 words of length 4

Unable To Count Each Char In A String

Jun 5, 2014

I am trying to count each char in a string. For example A = 1, B =2, C=3, I am not looking for their binary value. So the word "At" would

AT= (A=1 +T=20)=21.

I know how to do this in C++ because I am able to treat a string like an array.

Java Code: void printFile()
{
int sum=0;
String line;
for(char cr ='A';cr<'Z';cr++)
{
for(int i=0; i<myList.size();i++)

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.*;

I am trying to count the number of occurrences of a string in an array list. I used the following code:

strings is the name of the array list and search is the string that I am trying to count the number of occurrences of.

Read Through A String / Count How Many Vowels There Are And Print Out When Detected

Sep 15, 2014

So I need to write a program that reads through a String and counts how many vowels there are and prints them out as it finds them. This is what I have so far:

if (vowel == 'a' || vowel =='e' || vowel =='i' || vowel == 'o' || vowel == 'u'){
numberOfVowels++;
}

The problem is that I can't figure out how to print out the character once it detects it as a vowel.

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();
}
}

Using Count Element Method To Count Occurrence Of Characters In Array

Jun 30, 2014

I have an array with the following characters {'E', 'L','E','P','H','A','N','T','P','O'}

now, I need an array that will store the first array such that only the occurence occurs e.g {'E','L','P','H','A','N','T','O'} Notice that the characters 'E' and 'P' occur twice and as a result were not repeated the second time in the new array.

How would one go about this using the counting elements technique?

I tried this but not sure how to use the counting elements technique.

char [] arr = new char{'E', 'L','E','P','H','A','N','T','P','O'};
char[] bucket = new char[(arr[0] * arr.length)];
for (int i = 0; i < len; i++)
bucket[arr[i]]++;
