Program Can Accept Multiple Filter And Sort Commands At One Time
Mar 9, 2014
What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.
However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:
-year:<year(s)>
-rank:<rank(s)>
-artist:<artist>
-title:<title>
-sortBy:<field>
Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.

We have a requirement that we need to have text area/text box on screen to accept multiple languages like (Spanish and russian) that means user can able to enter their text data either in any language like english,russian and spanish(It should be possible to enter the comments in russian and spanish languages). Is it possible to implement in java/j2ee?
A friend and I are working on a project in which we must test "super anagrams" (anagrams in which all characters in the first string are found in the second). We have a driver and definitions class pasted below:
Definition class SuperAnagram{ String left = new String(""); String right = new String("");
[code]....
In the driver class, we get "cannot find symbol" errors at the beginning of cleanStrings and isSuper, both inside and outside of the if statement.
I am trying to create a fortune teller and everything is running fine except the program does not prompt you to answer the questions
Do you like donuts? and What did you have for breakfast?
Here is the code this is in Bluej :
import java.util.Scanner; public class FortuneTeller { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); System.out.println("Welcome to Fortune Teller");
I was trying to write a program that will accept values and transform the scores to grade. Like 70 and above will be given A from 60 to 69 is B, from 50 to 59 is C, from 40 to 49 is D and below 40 is F. I have defined the variables, for the textfield, am confused on how make this hapen on just a click of the comand botton.
I am attempting to write a program that accepts input of a positive integer, reports each digit and then the sum of all digits. This is what I have so far:
*/ package numbersum; import java.util.*; public class Week4NumberSum { static Scanner console = new Scanner(System.in); /** * @param args the command line arguments
[Code]...
It works if I enter 1234567891 (10 digits) Enter a positive integer: 1234567891 digit: 1 digit: 2 digit: 3 digit: 4 digit: 5 digit: 6 digit: 7 digit: 8 digit: 9 digit: 1
The sum of the digits is 46
But if I enter 11 digits, it fails:
Enter a positive integer: 123456789123 (12) Exception in thread "main" java.util.InputMismatchException: For input string: "123456789123" at java.util.Scanner.nextInt(Scanner.java:2123) at java.util.Scanner.nextInt(Scanner.java:2076) at week4numbersum.Week4NumberSum.main(Week4NumberSum. java:26)
java - Scanner error with nextInt() - Stack Overflow gives me some infor for InputMismatchException - which I find described as In order to deal with this exception you must verify that the input data of your application meet its specification. When this error is thrown, the format of the input data is incorrect and thus, you must fix it, in order for your application to proceed its execution.
I don't understand why the 10 digit integer is OK but the 11 or > digit integer is a mismatch.
Write a java program to accept a string, float and an integer as command line arguments. String value should be displayed. Also the program should display the maximum value of two numbers. Use Integer.parseInt() and Float.parseFloat()
I have a button in jsp, when the onclick event is fired, it will send the request to someaction.do to generate a report and display that report in a new window.
After clicking the button to generate the report, in the business class a sql query is getting executed.
If the query result has less data, then I don't have any problem, I could view my report page.
If the query result has more data, then the query takes at least 5-6mins to complete. However, before the query completes its execution, the same request is automatically invoked again. Due to this the report is not getting generated because [...of the multiple requests?], the browser shows an Internet Explorer error and ends up at a blank page.
No exception is thrown and the only place I could find the place of query execution it stops and starts as a new request from web.xml with Servlet Filters, Action.
Note: For a single .do request, the request is getting repeated for 3 times. Overlapping of request also takes place.
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;
I am working on my generic insertion sort program. When I completed and run my code, I am having trouble with my code. So, I am just trying to see if I get an correct array from a file. However, i just get so many nulls in the array. Therefore, I can't run my insertionSort function because of null values.
I'm doing a project with very defined requirements. Input and output will be done to and from a file. Both the input and output files should have the same format. Each file will consist of a series of lines formatted as follows:
Year Rank Artist Title
That is, each line of the file will consist of the year, rank, artist, and title of a single song, with each of the fields separated by tabs ( ). Output files must maintain this format—you should be able to use the output file of one run of the program as the input to another run.
The first part of my project is to make a Song class, with 6 methods:
public static Song parse(String s) { //Parse a string of the form “Year Rank Artist Title” and create a Song object with the given values. } public int getYear() { //returns the year of the song } public int getRank() { //returns the rank of the song
[Code] .....
So far, I have worked out my Song class like this:
Java Code:
import java.util.Scanner; public class Song { private int year; private int rank; private String artist; private String title;
[Code] ....
I know there's definitely a problem with my parsing, as I am getting the
Exception in thread "main" java.util.NoSuchElementException
when I attempt to input a test String at my variables.
Should I try using StringTokenizer and Integer.parseInt()? I think that perhaps the reason why an error is occuring is because the String is being parsed into Strings and there are no int values to be inputted into the year and rank variables.
I have been assigned to write a program that has a user input random numbers then the program is to sort them in different ways. I have the coding for the different sorts but, I have an error saying that I am missing a return statement in the "Bubble" method. I am trying to return "arr[i]" in the "for loop" which gives me this error, and when I try to take the "return arr[i]" outside of the "for()" loop the error reads the it cannot locate variable "i".
import java.awt.* ; import java.awt.event.*; import javax.swing.*; public class SwingSorts extends JFrame implements ActionListener { JRadioButton bubble; JRadioButton selection;
I would like my application to execute a command in cmd. The command looks like
start "" /D "C:Riot GamesLeague of LegendsRADSsolutionslol_game_client_sln elease s .0.1.55deploy" "League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 P3hNrXYZlaM3iJ9ximtzJWHbwLhvbimJ 953089676 EUN1"
So my question is how do I do this?
I tried this, (just copy paste the command):
package MyProject; import java.io.IOException; import java.io.InputStream; public class Cmd { public static void main(String[] args) { try { final Process process = Runtime.getRuntime().exec("start "" /D "C:Riot GamesLeague of
So, here is the question I have been working on: Write a java class named Time that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example the elapsed time is 9630 seconds, and then the output is 2:40:30 ).Hint: an hour has 3600 seconds and a minute has 60 seconds. Use Scanner class for reading the input.
Here is my code:
import java.util.Scanner; public class Time { public static void main(String[] args) { Scanner scan= new Scanner(System.in); System.out.println("Enter the elapsed time in seconds:"); int totalseconds= scan.nextInt();
[Code] .....
Now, I know I am supposed to use the remainder operator to figure out the time in minutes and seconds, but the hours has be a little confused. Right now this code compiles but gives me an exception.
I was told to create a program that prints the time between 00:00 (0:00 a.m.) and 23:45 (11:45 p.m.) in the 24-hour clock and 12-hour clock format like this:
Is it possible to write a program that changes the value of a certain variable when a certain predefined time arrives, without running the same loop over and over again (and stucking the computer)?
