Storing And Scanning String In Java?
Jun 10, 2014I am building an app, where I have to store the data eg: "hello ! how are you" in java as a string and then use scanner to get input and check if the entered word is present in the line stored. If it is stored then the entire sentence must be displayed. eg : if the stored string is "hello how are you"
if the entered string is "how", then the entire sentence "hello how are you" should be displayed.
Scanning User Input Text
Jan 17, 2014I've been trying to get user input as a text and then outputting one of 2 answers depending on the input.
import java.util.*;
public class kt_3_1 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

This program compiles but always returns "FUUUUUUUu", even if I'd typed "summer".
Scanning Non-txt Files With Unspecified Filename
May 15, 2014I want to make a tool that does the 2 following things::
- Open files that are not .txt but can be opened as .txt and return them as a string. It just returns an empty string at the moment.
- The filenames are unknown, just the file extension at the end and the the YYYYMMDD number in front are always the same, therefore I'd like the app to simply scan every file in the same folder (not the same file twice, obviously). How can this be done?
That's what I've got so far.
Java Code:
public String readFile(String filename) throws FileNotFoundException {
Scanner scanner = null;
File file = new File(filename);
String output = "";
try{

Scanning Known String And Not Input Typed By User?
Jul 29, 2014I'm having an issue with my program that needs 2 lines of input when I only want one. First I call Scan.nextLine(); to fetch a word. Then I want Scan.findInLine(word).charAt(number); to scan the string word for a letter instead of having to put another line in the console. How do I make Scan.findInLine(word).charAt(number); scan a single String instead of scanning input typed by the user?
View Replies View RelatedScanning Input File Then Running Applet
Oct 14, 2014So this is probably pretty simple but I can't seem to figure it out. My teacher wants us to write a code that scans a text file, then outputs some text based information AND displays an applet bar graph of the data sorta like this for the text:
Sample Bar Graph
1-10 |*****
11-20 |******
21-30 |**
31-40 |*
41-50 |***********
51-60 |******
61-70 |********
71-80 |***
81-90 |****
91-100 |****
and then an applet thats the same info just a little more graphic. My code interprets the input well, but when i try to make an applet output, the code basically forgets all of my variables and starts anew (when i just state the public static graphic (paint) class after everything) OR it refuses to scan the input file (if i switch the public class from main.....throw ExceptionIO to just public class graphic(paint))
Also, as a side note, any way to have java automatically determine how many separate lines there are in a text file without me having to manually count them.
import java.util.Scanner;
import javax.swing.JApplet;
import java.awt.*;
import java.io.*;
public class Project2 extends JApplet {

Scanning Text File For Email Addresses
Mar 2, 2014Write a program that scans a text file for possible e-mail addresses. Addresses look like this:
someone@somewhere.net
Read tokens from the input file one by one using hasNext() and next(). With the default delimiters of Scanner, an entire e-mail address will be returned as one token. Examine each token using the indexOf() method of String. If a token contains an at sign @ followed some characters later by a period, regard it as a possible e-mail address and write it to the output file.
Programs such as this scan through web pages looking for e-mail addresses that become the targets of spam. Because of this, many web pages contain disguised e-mail addresses that can't easily be automatically extracted and above that is says to modify a program from our chapter which is this:
import java.util.Scanner;
import java.io.*;
class NamedFileInOut {
public static void main (String[] args) throws IOException {
int num, square;
[Code] ....
This is the first time hasnext() and next() have been introduced to me, so whereas scan.nextInt() looks for integers, does hasNext() looks for strings or characters? the wording in the exercise text is confusing to me. so basically i should create a text file with a ton of strings and within that jumble of text, stick a few email addresses; then when the program asks the user for the input file name, use that text file's name correct? pretty sure i have it up to that point, but using the indexOf() is what i'm having trouble wrapping my head around. do i look for the index of "@" and "."? i could conceptually see how i could say if the indexOf(".") is three spaces before the end then i know it's a .com or .net or .org or whatever. but how would i use indexOf("@") when the "user name" AND the "provider" (i.e. @yahoo or @google or @whatever) have an infinite number of lengths? we haven't had literally any discussion on input/output in classes so i am totally green to this.

Opening A Serial Port In A GUI
Oct 20, 2014I have created a java gui application and I need to communicate through the serial port. I would like to open the serial port in the beginning of the application and then close it when the applications closes. The problem that I am having is that I created a method to open the serial port in the main function but I can not close the serial port on exit off the application. Is there away of having the serial port be setup so that all methods can access the serial port.
View Replies View RelatedScanning And Displaying Every Word From A Website Source Code Java
Feb 19, 2014I have been given a task to scan the contents of a websites source code, and use delimiters to extract all hyperlinks from the site and display them. We havent been told anything about how to do this so after some looking around online this is what I have so far:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

So my program can extract each line from the source code of a website and display it, but realistically I want it to extract each WORD as such from the source code rather than every line. I've looked around online but I don't really know how it's done because I keep getting errors when I use input.read();
How to make it extract each word from the source code?

View Replies View RelatedJDBC :: Oracle UCP Connecting To Wrong Port
Apr 10, 2015I am trying to connect to Sql Server database using Oracle UCP with sqljdbc4-3.0 JDBC driver for Sql Server,with different ports and instances.
– the issue is with the port being ignored in the server string.
For example, using port 1440 connects to the default instance (which is on port 1433) rather than MSSQLINSTANCE1 which is on 1440.
Below are Server hosts used.
sql005.sqlasoftware.com (connects correctly to the default instance)

1.What does the if-condition do?If the name of a monster in the array is equal to the name stored in the variable, return the monster's assigned value.
2.What does the for loop do? The loop condition simply loops through the whole arraylists. (In other words, it simply checks each Monster contained in the lists).
3.Assuming that the driver code compiles, explain what it’s use is? If the name of the monster is the same as the variable passed unto this method, return the number assigned to that Monster.
Coding AI Game Through Java
Apr 10, 2015The game has two players: x and o. The players take alternate turns, with player x moving first at the beginning of each game.
Player x starts at position (1,1) while o starts at (8,8).
Each turn, a player can move like a queen in chess (in any of the eight directions) as long as her path does not cross a square already filled in or occupied. After moving, the space vacated by the player is designated as filled and cannot be moved to again. Notice that only the space that was occupied is filled, not the entire path.
The game ends when one player can no longer move, leaving the other player as the winner.
The coordinate (1 1) indicates the top left hand side of the board.
The board is specified as a list of rows. Each row is a list of entries:
- is an empty square * is a filled in square x is the current position of the x player o is the current position of the o player
The board will always be 8 by 8.
Your player function should take in the parameters as described above and return a move as a list in the format (row column) within 1 minute. If you cannot move, return (nil nil). The Tournament Referees will check for this. If you return an illegal move, the other player (and the Tournament Referees) will detect it and you will lose.
Additionally if your time expires you will lose.
Wages Calculator - Determine Total Cost Of Crew Departing From Port On That Day
Nov 27, 2014A wages calculator application is required that can determine the total cost of crew departing from the port on that day. To do this, the application reads from an itinerary text file containing each ship being loaded in the port that day, in the following format:
<ship id>
<journey id>
<l> // where <l> is the length in hours of the journey
<s> // where <s> is the number of crew for the ship for this journey
<rate> // for each s, <rate> is hourly rate of pay
Your application must calculate the total cost of the crew for each ship/journey and then compare it with a "recommended maximum journey cost" (RM) amount typed in by the user when the application is first run. If the total amount is less than or equal to RM then the details must be written to the screen and to an output text file called wagedaily.txt. If the amount is larger than RM then the results must be written to the screen only. Messages to the screen must indicate whether the crew cost is less than, equal to or larger than RM.
Your application should find the ship with the highest crew cost that is below RM and print this out as the final piece of output to the screen.
It has given me a bunch of ships and numbers to play around with in the code, here they are:
Monarch
M141
16
