Total Number Of Each Alphabetical Letter From A File
Nov 28, 2014
So far I've got it where the program is reading the file and returning
a:0
b:0
c:0
d:0
e:0
f:0
g:0
h:0
i:0
j:0
k:0
l:0
m:0
n:0
o:0
p:0
q:0
r:0
s:0
t:0
u:0
v:0
w:0
x:0
y:0
z:0
But I need it to print the letters and then the total amount of each character that is found in the file.
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

I am having some trouble with this program. The assignment is to write a program, given a seven-digit phone number, uses a PrintStream object to write to a file every possible seven-letter word combination that corresponds to that number. I have to avoid using 0 or 1. Here is my code.
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintStream;
import java.util.Scanner;
public class TelephoneGenerator
{
String phoneNumber;
char numberLetters[][] = {
[Code] ....
I am getting an error dealing with the main class.

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

I 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

I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.
First, convert letter to number. Second, restore number to word.
Words list: a = 1, b = 2, f = 6 and k = 11.
I have word: "baafk"
So, for first step, it must be: "211611"
Number "211611" must be converted to "baafk".
But, I failed at second step.
Code I've tried:
public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);
[Code] .....
Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk
What do I miss here?
How to distinguish if 11 is for "aa" and for "k"? D

I had a list of some numbers having a prefix A like A12 , A55, A76 ,A111 ,A888, A88 ,A880 A111 , A11,A1
I need to sort this list so the result would be A1,A11,A12,A55,A76....
How to do this. Can I use arrays.sort method to achieve the same or any other way.

I got a phone number problem. I get a list of phone numbers and a word file containing words, how could I need to see if I could match the phone number to 7 letter words, then see if I can match the first 3 numbers to 3 letter words and then the last 4 numbers to 4 number words. I figured all that out so far. The last part of this assignment is to see if I could match a combination of words together to match the phone numbers.
Example:
531 3259

Write a program that translates a number between 0 and 4 into the closest letter grade. For example, the number 2.8 (which might have been the average of several grades) would be converted to B. Break ties in favor of the better grade; for example 2.85 should be a B. Use a class Grade with a method getNumericGrade. why when I type .3 it tells me "Exception in thread "main" java.util.InputMismatchException" Or if there is an easier way to do this.
import java.util.Scanner;
public class Grades {
public static void main(String [] args) {
System.out.println("Enter a number between 0 and 4");
Scanner input = new Scanner(System.in);

I wanted to write a simple code that receives information from the user (double-digit number and above) and calculates it's numbers.
For instance- The user wrote a number- 234, the software will return the number 9 (2+3+4 = 9).
Tried to use a loop for that, but I got stuck since I didn't know what to write.
This is what I've wrote so far
Java Code:
import java.util.Scanner;
public class Calculate {
public static void main(String[] args) {
System.out.println("Please type a number larger than 9");
Scanner type = new Scanner(System.in);
String number1 = type.nextLine();
for( int i = 0; i < number1.length(); i++ ){
int calculate = number1.charAt(i);
}
}
} mh_sh_highlight_all('java');

Here is my problem: if I want to add a number of X consecutive values in an array and get the minimal total value along with the indexes that caused this result, how can I do that?
For example:
X = 2
array[4] = (5,2,8,6,7)
start adding every 2 consecutive values as following:
array[0]+array[1] = 5+2 = 7 //minimal value
array[1]+array[2] = 2+8=10
array[2]+array[3] = 8+6= 14
array[3]+array[4] = 6+7=13
output:
minimal value = 7
indexes of minimal values are: 0 and 1

I have a problem with functions connected to strings.
I have a random String, e.g. "Hello World!" and I have to change every capital Letter into a small letter and vise versa. This alone would be fairly simple, but I have to do it with two other strings.
lowercase= "abcde...z" and
uppercase="ABCDE...Z". Every small letter stands at the very same position as the capital letter, but in the other string.
There should be a letter for letter search in lowercase and uppercase for the letters of "Hello World".
How I could solve the task, however I need a way to search the first string, here "Hello World", according to position. A statement which does: "Give me the letter of position x". This found letter should be able to be stored in a variable or else be able to be used by another statement. And it should be compatible with a for lope.

else
code ="B"002
name="Angela"
=failed this will not inserted into database
else
code="A"003

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder;
import javax.swing.*;
public class UseOrder {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.
I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

I am trying to sort an array that I have by alphabetical order but I am having problems. Firstly the code that I have used to sort the array may not even do what I need but havn't got far enough to test it yet so go easy on me . I have read in some places when searching how to do this that I would have to create my own bubble sort in order to achieve this but I was hoping that Java had a built in sort method/function. Secondly I lack the knowledge in java to be able to assign an existing array or even a variable to the newly sorted array as I need the unsorted version with the original name and the newly sorted version as another.
code (This is not all of the code, I decided to include only what I thought was relevant):
import java.util.Arrays;
public class Sentence {
private String words[];
public Sentence(String[] words) { this.words = words; }
@Override
public String toString() {
return "Sentence{" +
"words=" + Arrays.toString(words) +
[Code] ....
Is it possible to shorten the sort function to just this?
public String sorted() {
return Arrays.sort(words);
}

I'm doing an exercise we're you're supposed to sort strings in alphabetical order, without importing anything , not using the Arrays.sort() method.
I think I got the method down partially right, or it is on the right track, but it is completely not being applied to my answer. All it prints out in the console is the actual String array twice, without sorting anything.
public class arrayofstrings {
public static void sort(String[] a) {
String temp= "";
int min;
int i= 0;
