I need to round my variables to the nearest "tens" place and I'm having trouble doing so. Every time I run the program it comes back with a number ending in .0 even if its something like 11 / 3. How can I fix this?
public static void results(int game, int totalGuess, int best) {
double avg = Math.round((totalGuess / game) * 10.0) / 10.0;
I am trying to get this code to round up the average after the user inputs all 3 grades but i cant seem to get printf to work.
import java.util.Scanner;
import java.text.DecimalFormat;
public class Average {
static Scanner console = new Scanner (System.in);
public static void main(String[] args) {
String studentName;

Write a program that reverses a list of 15 integers preferably in place.
View Replies View RelatedI have this code line:
String sectionText = String.valueOf((int)percents.getYellowPercent());
And I want the integer value to be displayed, instead of double. This works, but when the program rounds the double into integer, if the number is for example 75,56 (this is %) or 3,5 I would like it to be rounded in 76 (or 3,6 for the other example) since as it is at this moment, when all the calculated integers are summed, the result is not 100%, but 99%.
My program is attempting to:
1. ask user to input a decimal
2. output 1 - confirms the input
3. output 2 rounds the input value to the nearest integer.
Here is what I have so far:

Results with input of 5.25:
run:
Enter a decimal:
5.25
You entered 5.25
The integer value is 5 YES however,
BUILD SUCCESSFUL (total time: 6 second)
However, if the input is 5.95 here are the run results:
run:
Enter a decimal:
5.95
You entered 5.95
The integer value is 5 Here I expect 6

Not sure how to ask the output of the variable integerOut to be rounded to the nearest integer?
Write a program to find the date of the monday which comes after the third friday of the nearest month.
Input : yyyy,mm,dd,Day
Output : yyyy,mm,dd,Monday
suppose the input is 29/1/2014
the output should be 24/2/2014

Honestly, I don't know how to start......
I noticed it is a huge success to have the backgrounds of games move and the character just move up and down and dodge obstacles.How Do I make a background that scrolls horizontally to the left? I know how to keep the character in place with up and down to move, but not sure how to go about making the background move with obstacles.
View Replies View RelatedI have two questions:
1. I read somewhere that instead of looping through every player (below), you use could Events to do it for you:
for (Player player : this.getPlayers()) {
if (player.getLocation().getX() == 10) {
}
}
I'm not sure as to how to use Events in place of a for loop. I've been thinking on this for days, but I'm still stuck. Any example of using an Event instead of a for loop?
2. Is there any way to accept multiple connections on a server without using a while loop? Maybe use Events to handle the acceptance of connections?
Is it possible to enable & disable "jdk.certpath.disabledAlgorithms" property programmatically. I want to remove all disabled Algorithms for some time and later I will enable it.
Or is it possible to enable only for a particular place & not in a JVM level. I want that Algorithm need to be enabled for a piece of code, but I don't want it to the remaining part of the application.
I am making a Dice Roll GUI and I have most of it down and I only need this constructor to work for the program to work (I think). I don't know where to place the constructor, I tried placing it around the RollButton class but it still didn't work and gave me java error constructor in class cannot be applied to given types
Here's my constructor:

this.panel = panel;

I am currently trying to solve a programming problem on this site, and the problem includes working on a 100 digits of decimal places of a certain irrational number. I tried using BigDecimal class but it displays, correctly me if I am wrong, just 20+ decimal digits. Is there other way to do this?
View Replies View RelatedI am trying to convert the double grossPay to 2 decimal places but cannot get it to work ,I am unsure of the correct way of doing this but this is how far I can get

double grosspay = 0;
grosspay = (Orate * overtime) + (salary / 26);
DecimalFormat df = new DecimalFormat("#.##");
return(df.format(grosspay));

I have 2 JSF applications - Let me say A and B.
Application A uses JSP and Application B uses XHTML.
Now, I want Application B also get the same look and feel as Application A.
For this purpose, I have to recode the complete JSP page (of Application A) into XHTML (in Application B).
My question: Is there any better way, like reusing all the content of JSP in XHTML or something like that.
Could I replace the existing XHTML content with the JSP content with some minor modifications?

2)Inside main() method like above
Will these two approach makes any difference ?

View Replies View RelatedI'm not sure why, but whenever I try to get a value out of a double, it only extends to one decimal place. For instance, (825 / 805) would become 1.0000 (after being run through a DecimalFormat object) instead of 1.0248 like I need it to be (and should be if what I know about primitive variable types is right). Why is the double variable type not giving me the precision I want and, more importantly, how do I fix this?

How do you remove from an ArrayList at a particular index then add back to that same index without the removal causing the ArrayList to compensate for the loss of them item and moving the empty space to the end of the array list?I've tried:
public void dischargePatient(int bedNumber) {
if (bedNumber < beds.size()) {
beds.remove(bedNumber);
}
}
But this moves the bed at bedNumber to the end of the ArrayList after removing the patient from the bed. How do I keep it at bedNumber?
Any way to place leading zeros onto numbers without having to convert them to strings? Is such a thing possible?
View Replies View RelatedI'm trying to figure out the necessary code for reading integers from a text file, then placing them withing the two-dimensional array I have created, and then finally printing the array using a nested for-loop. I have attached the file I would like to read from. I'm having trouble figuring out how to reference the text file with the integers, and also how to properly create a dynamic preface for each row of the array. I want the preface to display as "Week #: ", with # being the row number. I tried to create an integer to be used that way, but NetBeans tells me whatever integer I declare has already been defined in method main. I know I need to use scanner to read the file. I would like the output to display like this:

I have a web application project built in Spring MVC 2.5. There are some EL expressions which are used in JSP as below:
${status.value}
${status.expression}
${status.errorMessages}
But, I coudln't find any place in Java/JSP where the value for status is being set. What could be the possible place where the values for status is being set.
As the code is client specific, so, I couldn't paste the specific code over here but I have searched in whole workspace i couldn't find a single place where values for status is being set/assigned to.
I'm having trouble formatting my output and issues with the decimal places. Here's my code:
import java.util.Scanner;
import java.text.DecimalFormat; // Imports DecimalFormat class for one way to round
public class lab3 {
public static void main(String[] args) {
String heading1 = "Hour", heading2 = "Distance Traveled";
int timeElapsed, hour, speed;
[Code] ....
And here's my output (Click on the image since it's pretty small):
javaIssues.png
Issue:
1) The Hours 2 and 3 aren't aligned to 1.
2) The 80 and 120 in Distance Traveled have 6 decimal places when it should not have decimals.
Ex. If I type 5943, the program will say
mill = 5
hun = 9
ten = 4
uni = 3
get the picture I had to translate the decimal value names from a different language.
This is what I have tried...,
Java Code:
import java.util.Scanner;//Permite el uso de leer el teclado del usuario
public class DeterminarValorDecimal//Nombra el documento
{
public static void main(String [] args)//Podemos ver la clase
{
[Code].....
But what this does is I have to enter the single digits one by one. I want to be able to type the whole number. Is there a method that reads the length of the whole number and lets me classify each digit so I can do what I want to do?
