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

I think I need to use string.split instead of stringtokenizer and the while loop is incorrect it needs to loop equal to the number of letters in the longest word. But how to do either of these ?
The goal of this code was to create a program using main method java to analysis a piece text which has been entered from a user.
They do this by entering the text into a scanner which is then analysed by the program. The analysis is to produce word frequency, for example " This is a test" produces this results:
This is a test
1 letter words: 1 2 letter words: 1 3 letter words: 0 4 letter words: 2 5 letter words: 0
The bit that I'm stuck on is producing a mean/average, My mind telling to divide
counts.length by str.length
But I'm not the Best at java and I've tried to implement this but all I get are errors.
Code:
import java.util.Scanner; public class While_Loop { public static void main (String[] args) { while(true){
import java.awt.*; import java.applet.*; import java.awt.event.*; public class Assignment extends Applet implements ActionListener { TextArea textInput = new TextArea(); // user input Button analyzebutton = new Button("Analyze"); Button resetbutton = new Button("Reset"); Label lbloutput = new Label ("Please enter text into the textbox!");
I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() { System.out.println("There are " + findUniqueWords(root, 0) + " unique words."); } private int findUniqueWords(Node subTree, int uniqueCount) { // Base Case: At the end of the branch if(subTree == null){ return uniqueCount;
public static void main(String[] args) throws FileNotFoundException, IOException{ // TODO code application logic here FileReader fr = new FileReader("gautam.txt"); BufferedReader br = new BufferedReader(fr); int line = 0; int word = 0; int character = 0; String s; while((s=br.readLine())!=null)
I am trying to split a string based on length(example length 5) of the string. But I am having a issues with this substring(start, end) method. I get all substring which are of length 5. But if the last substring is less than 5 then I am not getting that last substring. But I need the last substring even if it is less than 5.
The problem asks me to write an expression whose value is the number of characters in a specific string. Normally, it would be a simple task of using the String.length() method, but that is not allowed. In fact, no variable declaration is allowed (it's a MyProgrammingLab assignment, if any are familiar).
Simply put, if I have a String "This is a sample string." is it possible to find the length without assigning it to anything?
In other words, the code must be able to go into the parentheses of System.out.println( ); and correctly print the length of said string.
The answer, for those curious:
System.out.println("This is a sample string.".length());
I didn't know the .length() method could be called on a literal. Now if only I could find out how to close this thread...
The String class stores the characters of the string internally as a private char[] and calling someString.length() results in getting the length field from the character array. I am looking to get the details on how the length is implemented. I understand it is a field, but in the original question I provide sample code and really want to know if/how the resulting byte code may differ when compiled, perhaps I am just not seeing the simple answer through my confusion.
I am currently trying to count and display all the vowels in a set of given strings and can't seem to figure out what to do. I was able to print the line with the most vowels, but i also need to display them. The code is listed below and the given output.
public class Strings { public static void main(String[] args) { String sentence = "I am currently studing Computer Science." + "My name is whatever and I am orginaially from the state of Virginia." + "I recenetly separated from the Air Force where I served on the Presidental Honor Guard.";
[Code] ....
The output that i am getting is:
I am currently studying Computer Science . My name is whatever and I am originally from the state of Virginia. I recently separated from the Air Force where I served on the Presidential Honor Guard.
The line with most vowels is:
I recently separated from the Air Force where I served on the Presidential Honor Guard.
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.

I am attempting to count the unique strings (a.k.a flowers) in the array along with a count of any duplicates. An example is embedded in my code below. I've only pasted the part of the program I am having trouble with. I can't figure out what I am doing incorrectly.
private void displayFlowers(String flowerPack[]) { // TODO: Display only the unique flowers along with a count of any duplicates /* * For example it should say
I am trying to count the number of non_blank characters in a string. If there are no leading blank spaces it works fine but say i add three spaces in front it doubles the non blank characters.
import java.io.*; import java.util.*; public class countCharacters { public static void main(String[] args) throws Exception { String str1; int count; count = 0;
I am trying to count the number of occurrences of a string in an array list. I used the following code:
int count = Collections.frequency(strings, search);
strings is the name of the array list and search is the string that I am trying to count the number of occurrences of. My program compiles correctly, but when I enter the string to search for, I get the following error: "Exception in thread "main" java.lang.NullPointerException at java.util.Collections.frquency(Collections.java:37 18)
Why am I getting this error message and how do I fix it?
I have to write some code to take names from the user and then order them in alphabetical order and then print them out which i have managed to do. However, i can't get it to count the characters in the names that the user enters or count the amount of vowels in the names.
This is the code ive written:
import javax.swing.JOptionPane; import java.util.Arrays; String[] names = new String[9]; int i; names[0] = JOptionPane.showInputDialog("Please enter a name"); names[1] = JOptionPane.showInputDialog("Please enter a name");
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:
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:
So the exercise I'm working on says to have the user enter their name and the program will output their name with the last name in all caps. i made it work BUT the only way i could figure it out was to ask for the first and last names separately creating two strings rather than one.
Of course I want to make it work how it's supposed to (with one string) so that I'm learning. I'm just having trouble conceptualizing how exactly (with varying lengths of names) to tell the program to only capitalize the second word... at first I thought create a substring beginning with the first letter of the last name and ending with the last...but again, therein lies the issue of varying name lengths.
is there a way to create a substring that beginIndex's at the first "space"? then i could just leave the endIndex parameter empty and it would take the whole word into a new string. and from there utilize toUpperCase to the new string?
Here's my code asking for the first and last names separately.
import java.util.Scanner; class nameEcho { public static void main ( String [] args ) { Scanner scan = new Scanner( System.in ); String first; String last;
I'm very new to Java, and I'm writing a code to search a string to see how many times the word "dog" is found in it. I'm not sure if this is error-free or the most efficient, but I'd like to keep it simple.
public void run() {
String input = new String("The Dogman was no ordinary dog, nor man, but rather a peculiar dog-like man who barked like a dog, and panted like a dog, he even ate like a dog. He owned a dog named Doglips, and interestingly enough, his favorite food was hotdogs.");
println(input); int index = -1; int count = 0; print("Counting dogs:"); inputarray = input.split(" ");
What I need to do is ask the user to input some text and then turn it into pig latin. I am confused on how to select each word from the string to determine if it ends in a way or ay. I am to assume that the letters are all lowercase and the text ends with a period.
import java.util.Scanner; public class Trial { public static void main(String [ ] args) { Scanner input = new Scanner(System.in);
