Requiring User To Enter Word / Sentence To Encrypt Or Decipher
Apr 10, 2014I've been given an assignment for my Programming Fundamentals class that requires the user to enter a word/sentence to encrypt or decipher, as well as requiring the user to enter a key in which to encrpyt/decrypt the input by.
So a = no shift, b = a shift by 1 and so on.
But I'm completely lost as to what to do, and after searching for Vigenere Cipher topics, they look completely different to mine and (hardly) include prompts?This is my code:
/**
* @(#)VigenereCipher.java
*/
import java.util.Scanner;

Write Out Whole Sentence - Counting Characters
Sep 16, 2014public class Setning
{

skrivHeleSetningen(setning);
}
private static void skrivHeleSetningen(String[] setning) {
[Code] .....
What this do is:
First write out the whole sentence (WORKS)
Write out number of words (WORK)
Then I would like it to write out number of characters (DOESN'T WORK)
The arguments are given in "run configurations" using eclipse
Reverse Number - Get Input And Result In Same Line
Feb 11, 2015I'm having trouble with a program, reversing numbers. I got the program itself to work! However, I am having an issue with the output.
import java.util.Scanner;
public class p1a {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
int n;
int reverse = 0;
[Code] .....
If I were to input, say 2341, I would get this: The reverse of 0 is 1432
The 0 should have been 2341, or whatever I input. What am I doing wrong?
I tried to move line 21 : (System.out.println("The reverse of " +n+ " is "+reverse);
Above the while loop, but instead get:
The reverse of 2341 is 0
How can I get my input and my result together in the same line?
Read Line From File And Save First String As Word And Remaining As Meaning
Jul 6, 2014I have written the code to read the line from file and save first string as word and and remaining string as meaning..
E.g.: innovation a new method, idea, product, etc.

Output Contents Of Input File In Alphabetical Order One Word Per Line
Jun 22, 2014I am having a lot of trouble with this lab. basically I have to make a text processor to read in code put it into a file and output the contents of the input file in alphabetical order one word per line. I have to reference the string varaibles input_filename and output_filename.
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import java.io.File;
public class TextProcessor {
[Code] ....
these are the guidelines to said lab:
1. In the main method define two Strings called input_filename and output_filename. I will be setting these Strings to my own file names for testing your code, so make sure you get these variable names correct, and that you use them properly in the following steps.
2. Read in the text contents of the file referenced by input_filename.
3. Split the contents of the input text into separate tokens, using whitespace as a delimiter.
4. Lower case the tokens.
5. OPTIONAL: remove punctuation
6. Alphabetize the tokens.
7. Using output_filename, write the alphabetized tokens to an output file, one token per line.
8. Be sure to close file streams - no resource leaks!
9. Use methods to separate functionality in your program where possible

Make Program That Tells User To Type Sentence?
May 21, 2014Ok, so I have to make a program that tells the user to type a sentence and at the end of the sentence a "." must be put to end the program. If a "." period is not entered, it must re-prompt the user to enter a period. On top of all this, the program has to count the number of letters in the sentence. I cant seem to get the while loop working and I cant find anywhere how to make a counter count the number of letters.

View Replies View RelatedWrite Application That Display Numbers 1 To 4 On Same Line
Jul 22, 2007I'm going to be taking an object oriented paradigm using java during intersession in a few months. I'm trying to brush up on it a bit. The problem is. Write an application that displays the numbers 1 to 4 on the same line, with each pair of adjacent numbers separated by one space. Write the program using the following techniques:Use one system.out.printLn statement.Use four system.out.print statement.Use one system.out.printf statement.
This is what i have so far .
Java Code: public class Display
{
public static void main(String [] args) {
System.out.print("1 ");
System.out.print("2 ");
System.out.print("3 ");
System.out.print("4 ");
System.out.println(" ");<----is that what that is supposed to look like, and where it goes?
System.out.printf(" %s %s %s %s ");????
}
} mh_sh_highlight_all('java');
i cant test this my console isn't working right, and i haven't finished my compiler install.
How To Write Import Statements And Use Its Class Components In One Line
Feb 5, 2015I was wondering if I could write this code in one line.
import java.util.Scanner;
public class Test
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
char ch = sc.next().charAt(0);
}
}
Can I combine "import java.util.Scanner","Scanner sc = new Scanner(System.in);" and "char ch = sc.next().charAt(0);" in one statement? The object created from the class Scanner may be anonymous but it doesn't concern me!

Word Counter Program With A Constructor
Mar 4, 2014Create a WordCounter class with a constructor that takes a file name as a parameter. The class should have two fields: one for the file name and one for a HashMap to store word count information. The constructor should call a private method, countWords, that reads in the file and counts the word frequencies. The class should contain a get method for each field, as well as a print method that prints out the map in the following format:word:frequency. When printing, the map should be sorted by either the word order or frequency (Hint: see Collections.sort)You should include the sample text file on Blackboard
import java.io.File;
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.Scanner;

Creating Number To Word Program?
Apr 1, 2015I was given the assignment of creating a number to word program for my first college java programming homework.
Here is what I have created so far :
import java.util.*;
public class PrintNumberInWord { // saved as "PrintNumberInWord.java"
public static void main(String[] args) {
int number = 5;
Scanner sc = new Scanner (System.in); {
System.out.println ("Enter a number");
System.out.println(" ");
if (number == 1) {
[Code] .....
The first lines were made for us so we could follow a guideline, however, no matter what I type the command prompt displays 5 to me, I know thats because 5 is defined in the beginning but backspacing 5 causes the program not to work at all, how can I get this program to work properly?
How To Make Hangman Program Work For Phrases With More Than One Word

Program That Memorizes Elements Formed By A Word And A Number
May 24, 2014i'm trying to do a program that memorizes the elements formed by a word and a number. For example, if I write ABB 3, AB 2, ABB -2, ABC 5, ZZ 2 the program will write:
ABB 1 (the result of abb (3-2))
ABC 5
AB 2
ZZ 2
Also, should write:
2 AB ZZ
5 ABC
1 ABB
I've tried to do it with a TreeMap but i don't know how it works.
Multi-word Hangman Game - Spaces Not Displayed When Program Run
Apr 9, 2015I created a simple Hangman game. It functions correctly, the only issue is when the file contains a phrase (2 or more words), spaces are not displayed when the program is run. For example, if the phrase was Java Programming Forums.
It would appear as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
I want there to be spaces in between the words. How could I fix this? What would I need to add to my code?
import java.util.Scanner;
import java.io.*;
public class hangman{
public static void main (String[] args) throws FileNotFoundException{
Scanner kb = new Scanner(System.in);
String guess;
String guesses = "";
int wrongGuess = 8;

Command Line Program
Feb 8, 2014I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.
Java Code:
Scanner scan=new Scanner(System.in);
System.out.println("Enter the music directory:");
String path=scan.nextLine(); mh_sh_highlight_all('java');
how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?
