How to use the scanner class to ask for a character?

Hey guys, this is my assignment:
Ask the user for a single letter and a sentence, and print out the
number of times that letter shows up in the sentence.
Please tell me how to scan for a character. I tried this:
import java.util.Scanner;
public class Frequencies
    public static final void main(String[] args)
        Scanner scanner = new Scanner(System.in);
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter a sentence");
        String x = scanner.next();
        System.out.println("Enter a letter to look for");
        String y = scan.next();
        char z = y.charAt(0);
        int chara = 0;
        for(int i = 0; i<x.length(); i++){
                if(z==y.charAt(i)){
                        chara = chara++;
        System.out.println("There are " + chara + " " + z + "s in the sentence");
}and got the error after Running (not compiling):
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 1
        at java.lang.String.charAt(String.java:687)
        at Frequencies.main(Frequencies.java:16)I thought this meant that I was asking for the character in postition 1 of string y, but in my code I wrote position 0
when I tried inserting words in the character place (just to see what happened, not expecting functionallity, I got
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: [NUMBER OF CHARACTERS]
        at java.lang.String.charAt(String.java:687)
        at Frequencies.main(Frequencies.java:16)Please help.
The assignment isn't due nor graded, this is just killing me lol.
Thanks in advance

I know you're trying to help, but this isn't really doing it. It does nothing to address the source of the OP's problem. The way he's doing it now is almost right. He just needs to do a tiny bit of detective work to fix a small bug. Tossing off a totally different approach, with no explanation, is not particularly helpful.Your right jverd I skimmed the OP's problem too quick;y and in tern didn't understand it fully. After reading the post thoroughly I saw that the problem can be solved by taking the sentence the user enters and then converting it into a array of characters. Then searching for the specific letter the user enters is achieved by comparing it to each individual element of the char array. Then incrementing a counter variable each time a match is made. I hope this example code solve your problem.

import java.util.Scanner;
public class SentenceReader {
    public static void main(String[] args) {
        int counter = 0; //Amount of time the letter appears in the sentence
        char letter;    //Letter the user search for
        char[] sentenceArray; //char array to hold the elements of the string the user inputs
        String sentence; //sentence the user inputs
        Scanner UserInput = new Scanner(System.in);
        System.out.println("Please enter a sentence! ");
        sentence = UserInput.nextLine();
        sentenceArray = sentence.toCharArray(); //splits up the users sentence into a array of char
        System.out.println("Please enter a letter to search for ");
        letter = UserInput.findWithinHorizon(".", 0).charAt(0);
         for(int i = 0; i < sentence.length(); i++){
                if(letter == sentenceArray){ //search to see if the letter of interest equals to each char (letter) of the array
counter++; //increments the amount of time the letter appears, set to 0 by default
System.out.println("The letter appeared " + counter + " times in the sentence"); //Displays the result :) I love programming

How to use a scanner!

I'm writing after 3 hours of trial and error. I've a Canon Lide 20 and I've downloaded and installed the driver and scanbox software. I confirmed that the device is connected to my mac.
The problem is that the canon scanning software wants me to link it with a software to import the scanned image. This can be photoshop (which I don't have). Any other free application that works?
Image Capture doesn't work.
Here is what I get from Canon: ScanGear CS is an Adobe Photoshop compatible plug-in driver. If an application program is compatible with Adobe Photoshop plug-in drivers, then ScanGear CS can be summoned from within that program by installing ScanGear CS in the plug-ins folder of the program.
* To find out whether an application program is TWAIN-compliant or Adobe Photoshop Plug-in compliant, please contact the manufacturer of that program.
* Contact the manufacturer of the application program for instructions for summoning ScanGear CS from within the program and for operating procedures for that program.

I have a Canon 8400F flatbed scanner, OS 10.5.4, and use Canoscan Toolbox version 4.9.3.4. On the menu that it opens you can choose to save your scanned image to a file by using the "Save" choice on the Canoscan menu. I tested it by asking it to save a scan to my Desktop. Canoscan put the scan into a folder named with today's date. You should be able to scan all your images to this folder then use them as you wish. Canoscan is a bare-bones program but it allow you to do a number of things with your scans (email, print, copy, etc.). For better control make sure the box "Display the scanner driver" is checked. The download library at Canon USA has the Canoscan Toolbox program in file CSTb4130MXE.dmg.gz.

What do you mean by 'the professional way'? If you are asking about a TWAIN interface you need to look at http://helpx.adobe.com/photoshop-elements/kb/twain-installed-photoshop-elements-11.html.

How to import from scanner?

I have multifunction HP psc 2210xi all in one printer/scanner. I can print with no problem. But I couldn't figure out how to use the scanner. Does anyone here use a HP scanner on the iMac before? What step do I take to make it available to software like iPhoto or Adobe Photoshop element etc.?
Thanks in advance.

You cannot scan directly into iPhoto. Scan your photos into a file on your computer and then import that file into iPhoto by dragging it into iPhoto's window.
Have you looked at HP's support directions? See this: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00033295&lc=en&cc=us&dlc=en &tool=useCategory&product=79502&rule=1571&dest_page=useCategory
When asked for location for scanning, choose a file folder that you have created for your scans.
You should also do a search in this forum looking for more info on scanning. (I tried to do this for you, but for some reason Apple's site won't allow this right now).

Downloaded ringtones to microSD card but can't figure out how to use them

I downloaded a bunch of ringtones and I can find them if I go to "Files/ringtones" on my microSD card, but when I try to use one in Settings/sounds/phone ringtone they are not there. I can't figure out how to use them. Can anyone help?? Thanks!

When I go to Music app, the ringtones aren't in the list of artists/songs. They are stored in the ringtones folder so I don't think they would show up in the Music app.

How to use sd card drive on Windows 7 partition.

I have a 15" Mac Book Pro Model A1318 about a year old. I am running Windows 7 on the partition and the SD Card will not recognize the card. It works when running Mac Snow Leopard.

You use it the same way you do in Snow Leopard. How is the card formatted? If it is formatted for Snow Leopard then Windows can not use it.

how to use itunes gift card to buy apps on ipad 2? Do I need a credit card for it?

I'm sorry, but there is nothing that I can do to help you with this situation. I don't know why, but many people have problems when they try to buy gems in the Clash of Clans game. Personally, I wouldn't touch the game with a ten foot pole, but that's just my opinion.
You will have to contact iTunes Store Support and ask for their help. You can email them from here.

Qosmio F30-127: How to use SD card - no SD card drive icon

Could some one tell how to use SD in F30-127.
I was trying to get picture from my SD card.
I inserted into slot but no Drive ICON was displayed

Hmmm. Please check if the SD card slot was recognized in the device manager.
There should be no yellow exclamation mark!
Other hint;
- Remove the SD card from the slot
- Go to the device manager and remove the SD card controller
- Now reboot the notebook
- After new reboot the windows should recognize and install a new hardware. This is a SD card controller.
- Now try to insert the SD card again!
By the way; did you use the compatible SD card size?

How to use SIM card slot on W500

I found there is a slot for SIM card when I pull the battery out. I insert my SIM card and start the computer, however it won't recognize. I download and install Mobile Connect software, I got "no device found" message. How to use this function?

Hello LeadOrg:
Thanks for that reply.
What confuses me is this: There seems to be two or maybe three different cards available, as follows:
Vodafone and AT&T - HSDPA wireless WAN, which seems to address the following two items:
- Ericsson HSDPA Wireless WAN Adapter
- Qualcomm UNDP Wireless WAN Adapter
Verizon Wireless WAN (UNDP), which seems to address the following one item:
- Qualcomm HS-USB
I can't find any specifications in the Lenovo literature that clarifies which of the above items are suitable for GSM-900 and GSM-1800 (the frequencies used in Europe) and which of these items are suitable for GSM-850 and GSM-1900 (the frequencies used i Oz, USA, and Canada).
Further, Lenovo seems to be linking these two products to specific carriers (Vodafone and AT&T in one case, Verizon in the other case), and I use neither one of these companies - they don't operate in Canada. I use Rogers GSM when I am in Canada and Swisscom GSM when I am in Europe.
I am quite confused. I'd like to get a card that works with the two above carriers - but I don't know how to go about the process of selecting the appropriate card. The whole HSDPA, HS-USB and UNDP business totally confuses me. I always thought that UNDP was the United Nations Development Program...

HT204266 how do i get an app to be recognized under the camera setting to be able to use the scanner?

I have an app called goodreads and an in order to use the scanner it says I need to let the camera have access. to do so it is saying to go to settings, privacy camera and allow access to the app well I do that but under the camera it doesn't have that app listed and I don't know how to get it so it is there? I have tried deleting the application and reloading it and still nothing. any advice?

TThat means you're allowing access to your camera roll when you access the app - like Instagram.
doesnt mean when you open the camera roll - good read will be an option like Facebook, Flickr, twitter...
refer to the good read support pade
