I want to split it into 2 integers:

Formatting Double To Fixed Number Of Fractional Digits
Apr 6, 2014Where do I find a subroutine similar to this:
String formatDouble(double dblNum,int NumOfDecDigits) { }
For years I have been using output subroutines I wrote long ago.
Now I need this kind and can't remember where it is.
How do I print doubles to a fixed number of digits to right of the point?

View Replies View RelatedGenerating Double Number From The Range
Apr 18, 2014I am trying to generate a double number from the range [-1,2]
so what i did is this
xs[i]= Math.random() *(2-(-1))+(-1);
I did that as a loop to generate multiple numbers and i got this result:
initial x values 2.17 2.66 3.04 2.81 1.83 2.66 3.67 2.81 1.04 3.1 3 1.23 1.44 3.5 3.84 3.03 1.7 2.79 4 1.43
see some numbers are out of range! and i don't know why aren't there any minus numbers...
Double RelativeFrequency Value Which Does Calculation / End Result Is Number With Lots Of Decimal Numbers
Nov 24, 2014for (int i = 0; i < letters.length; i++) {
double relativeFreq = (onesAverage()/letters[i]);
char a = characters.charAt(i);
double j = score[i];
System.out.printf();//ToDo
Above is my current code. Basically- There is a string called characters of length 26 (1 char for each letter in alphabet), a double relativeFrequency value which does a calculation and the end result is a number with lots of decimal numbers. The score array has set double values within the array.
What I want to do is create a print f statement where I print out each of the values I initialized above WITH specific amounts of spaces in between. So it should be in this order:
a (spaces) j (spaces) relativeFreq (newLine).
Between J and relativeFreq there should be 4 spaces, however if the value in relativeFreq is greater than 10 (it won't be greater than 100)- then there should be 3 spaces. Everytime I try to create a printf statement my code ends up crooked for some of the values.
for (int i = 0; i < letters.length; i++) {
double relativeFreq = (onesAverage()/letters[i]);
char a = characters.charAt(i);
double j = score[i];
System.out.printf("%c %.4s %.4s%n",a, j, relativeFreq);
User Input Data As String And If Verified As Valid Number Then Convert Into Double
Nov 11, 2014I am writing a code in which a user inputs data as a string and that data must be verified as a valid number. A valid number is anything from 0-100. Then all valid numbers are converted into double numbers.
I am having trouble in how to write the validation part of the code.
Is it suppose to be an if, else statement? And if so how is it suppose to be validated?
Formatting Array List?

Mine looks like this:

Formatting User Input
Feb 4, 2014I have been given a piece of work to do for College that requires me to format user input. For example: This is an example of text that will have straight left and right margins after formatting
will transform into:
This..is..an.example
of..text..that..will
have..straight..left
and...right..margins
after.....formatting
The user inputs the width, in the case above being 20. Each line has to therefore be 20 characters long. All spaces are to be replaced with full stops.
This.is.an.example.o
f.text.that.will.hav
e.straight.left.and.
right.margins.after.

public class Main {
public static void main ( String args[])

Formatting Integers Into Money
Apr 15, 2014Having the following fields for my money class.
import java.text.DecimalFormat;
public class Money {
//Fields for money will hold dollars and cents
private long dollars;
private long cents;
My task is to use those fields and make a toString method that returns them like a dollars sign. For instance, if there are 32 dollars and 40 cents, then in my String method I have to return something similar to this "$32.40."
I have already tried some of the methods, but they don't seem to work fine.
public String toString() {
DecimalFormat formatter=new DecimalFormat("$#0");
DecimalFormat formatCents=new DecimalFormat(".00");
return formatter.format(dollars)+ formatCents.format(cents);
}
Code:
import java.text.DecimalFormat;
public class Money
{
//Fields for money will hold dollars and cents
private long dollars;
private long cents;
[Code] ....
Actually changed a little on my code and I believe strongly this should work; however, doesn't seem to. In my demo,
public class Dem {
public static void main(String[] args) {
Money myMoney=new Money(7.10);
System.out.print(myMoney.toString());
}
}
I pass this, but I get "$700.00" as the answer... confused...
My calculation is wrong in the toString method, but still the cents do not appear to be showing.

Formatting Answers To 2 Decimal Places
Sep 8, 2014I've been scanning forums for answers to this problem, but most deal with simple programming that you might find in a classroom (i.e. "System.out.printf") which will not work in the GUI I'm attempting to complete. Here's the tale of the tape:
The GUI is a price calculator I'm developing for my company that takes input from drop-down menus and several Jtextfields and calculates the answer based on the values contained within each. It's completely done (and functional), so I'd rather not change too much if at all possible. Because I'm dealing with decimal values then I'm getting 9 decimal places in the output JLabel, though. In order to display the answer, I'm using a series of "totalPrice.setText(..." declarations.
Because there is a fair amount of text and the values in the calculation are constantly changing, is there a way to 'simply' format the output JLabel to display only 2 decimals? Or is there an alternative solution that would work--say with a JTextfield instead--without having to completely re-code the calculator?
Write TextArea To File Formatting?
Dec 10, 2014I want to write a text area to a file which I have accomplished however the formatting for how it is written into the text file is different. Is there a different library I must use to retain the formatting?
I'm using a BufferedWriter to write to the file
if (!file.exists()) {
try {
BufferedWriter output = new BufferedWriter(
new FileWriter(file));
output.write(textArea.getText());
output.close();
} catch (IOExcception io) {
io.printStackTrace();
}
}
If I write this into the text area:
DreamInCode
YouTube
Google
The text file contains text that says:
DreamInCodeYouTubeGoogle
Formatting Tables For Console Output?
Apr 13, 2014I am writing a class which formats console output as a table. It displays the type of an entry, the name of an entry, and the data for an entry. I am stuck on a required for loop which appends a tab character to a string, for formatting it as a table. It doesn't seem to be adding any of the tabs and I can't tell what I've done wrong. As far as I can tell the contents of the loop are never reached, and I can't make sense of it.

Error - Formatting Output String
Sep 28, 2014I have this error that keeps coming up any time I select one of my buttons. It actually doesn't hinder the performance of the project, everything works. But I am concerned I missed something and errors are never a good sign.On a slightly different note, I would like to figure out what the best way to format my output would be? I would like it to display as "100.00 F". I have a couple ideas on how to get the F symbol (or other symbol) by inserting something like
String degreesymbol = "F" or whichever it is and then returning that in the output string later. I can't get the decimal formatted correctly and I don't know how to print the degree symbol.Here is the code

How To Keep Colors / Layout And Formatting After Generating JAR

Formatting User Answer To Two Decimal Places
Nov 20, 2014I am writing a simple learning program that does basic math. Everything is working as needed except for when it comes to division. I need to know if there is a way to format the users input to two decimal places and that when the program checks the users answer against the division, it gives it a yay or nay. Right now, it wants the answer out to 12 decimal places.
So for 5/3
I would like it to accept the answer 1.67
not 1.666666666667
Is there a way to do this?
Arrays And Formatting Output - Data Integers
Jan 23, 2015I am just learning arrays or rather teaching myself about them and I am not to sure how they work and why. I understand that in order to set one up you do
int[] example1;
example1 = new int[]{01, 02, 03, 04};
But I don't really understand is why if you only need 3 data integers, why put the 4th one in?
Also with outputting data, I understand .print() and .println() but I am not to sure what .printf() does and then the formatting after that.
System.out.printf("%3d%11") // and then what you want to print
