Write A Program Using Loop And Break To Calculate Value Of Pi
Oct 5, 2014having some trouble doing this. Here are the requirements:
1)Write a program using loop and break to calculate the value of PI.
2)You can use the following equation to calculate PI. PI=4/1-4/3+4/5-4/7+4/9-4/11+4/13 etc.. The program shouldn't loop until the criteria is satisfied.
3)The criteria is the value of PI you get is very close to the “real” value (3.1415926), meaning that their difference
should be smaller than a very small numeric number, e.g., 0.0001).
4)The control structures you may need for this program are loop, if-else, and unlabeled break.
5)The output should have the format: for each iteration, it has iteration number and the corresponding value of PI until that
iteration. The last line would be the final value of PI.
Here is my code so far:
package ids;
public class IDS {
public static void main(String[] args) {
double pi = 0;
for(int i=1; i<=100000; i++){
if ((i%2)==0){
pi+=(4/(2*i-1));

How To Break A Single Long String Into Multiple Lines In Java Class
Jan 1, 2015I have created an application using hibernate and struts.In which a form is created where the user will enter all its personal details(for e.g name ,phone no. and address).

So the problem is if a long string is entered then while displaying that ,address comes on single line and the page is stretched.

View Replies View RelatedImplementing A FPS Counter
Jan 17, 2014Ok, so I'm making a game with a space ship that flies around the universe and discovering new planets. It works fine so far, but I'm looking to make it perform better and be better compatible with lesser-processors.So, I'm trying to put in an FPS counter and an entirely new game loop so that my game can decide for me what FPS I should use.
I have two classes. Heres the big, main one: [Java] package cyentw.game.src; import java.awt.Color; import java.awt.Font; impor - Pastebin.com *I want to change the loop and put an FPS counter in around line 456, you can scroll past the rest if you'd like*And heres the init frame one, in case you'd like to see it for some reason.
Java Code:
package cyentw.game.src;
import javax.swing.JFrame;
public class Start extends JFrame{
public static JFrame frame;
public static int WIDTH = 500;
public static int HEIGHT = 500;
public Start() {
[code]....
how to make my game loop as quickly (or a bit slower) as it can, and my FPS is static.
Second Counter To Minutes
Apr 7, 2014I have a timer where it counts down from 300 to 0 then does something. But I want the display for the clock to show the time in minutes. I tried:
double showTimeLeft = timeLeft / 60;
o.setDisplay(String.format("%.2f", showTimeLeft) + " Minutes");
But Every so many seconds it skips like:
Time = 3.38
Time = 3.37
Time = 3.35
Time = 3.34
It skipped 3.56
How to do this right?
Increment Counter By Recursion
Mar 22, 2015I have a question related to the code below, that I do not understand. The aim is to count all files and subdirectories in an ArrayList full of files and subdirectories. So I have to count every file and every subdirectory.
The code concerning counting files is clear to me - every time d is of the type file I have to increment n by one. However I thought that I have to do the same thing in case d is a directory, so I would have written the same code for directories.
So what does "n += ((Directory) d).countAllFiles();" mean? In my understanding the method countAllFiles() is applied again on the object Directory ( as Directory is the class that contains this method), but how is n incremented by this? I thought n should be incremented by one as we did with files.
public int countAllFiles() {
int n = 0;
for(SystemFile d : content) {
if(d instanceof File) {
n++;

Confirm Dialog And Counter
Mar 29, 2014This is the code I have written so far. This program calculates tax from multiple tax payers.
import javax.swing.JOptionPane;
public class CalcutateTax
{
public static void main (String [] args)
[code]....
The problem is I cant think how to ask the use if he wants to calculate tax due for another taxpayer. If the user says yes, keep calculating, otherwise exit from the program. And how do I keep count of how many people got their tax calculated? Say for example,
JOptionPane.showMessageDialog (null, " We calculated tax for " + xnumber + " number of people.");
This is the question asked on my assignment ask the user if he wants to calculate the tax due for another taxpayer if so, do it again.At the end of the main method, output a message in a dialog box that says: Hello, We calculated taxes for [number of taxpayers].replace [number of taxpayers] with the actual number of taxpyers you calculated taxes for.
Declare Counter With Value Outside For Loop
Mar 29, 2015Is it possible to declare a counter with a value outside of a for loop?
I have a counter that will end prematurely in a while loop during various iterations and I want to pick it back up in a catch all for loop at the end
Let's say I have a while loop
while(something) {
total++
}
then after I have a for loop that I want to start at total but would rather do that then make a new counter variable.
for(total;total < 20;total++)
Is something like this possible or is this a horrible thing to want anyways?

Counter To Count Random Occurrence
Jan 21, 2015I have 2 classes a main one and another class. In the other class I have a method that has:
String gInfo(){
String[] Behavior = {"Sleeping", "Running home", "Studying", "playing pool", "walking to class"};
int rNum = (int) (Math.random() * Behavior.length);
return Behavior[rNum];

I call the gInfo() in the main class and run it through a loop 20 times. What I'm trying to do is get it to count the number of times that each behavior happens. and how to get it to work correctly.
Swing/AWT/SWT :: FPS Counter Only Displaying Ideal FPS
Mar 23, 2014I have an fps counter in my game loop:
public void run()
{
long currentTime,timeDiff;
prevTime = System.nanoTime();
accumulator = 0;
boolean TRUE = true;
[code]...
When I print the fps variable to the terminal window, it show a value of ~59.9998 - very close to the frameRate of 60. That is to be expected, and works well. The problem is that when I deliberately make the game go really slow, by spamming a bunch of enemies, the game looks slow, but the FPS is still apparently ~59.9998. I thought that maybe the paint() method was not calling when it was supposed to, but that might not be the case.
This FPS counter should be working, I can't see where I have gone wrong. Is there a problem with the code, or is there another problem that might cause the screen to be redrawn 10 times a second with an FPS of 60?
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

Accessing Variables - What Is The Final Value Of Counter
Mar 7, 2015While reading head first java i encountered a problem(Pg. 90 chapter 4 - mixed messages).
Suppose in a class(say A) outside main() a counter variable is declared and initialized to 0.
In main() declared the array of objects of the class A.
Consider a while loop in which we increment the counter as follows:
public class A{
int counter = 0;
public static void main(String[] args){
A[] arr = new A[20];
int x = 0;
while(x<4){
arr[x] = new A(); //arr[] is array object
arr[x].counter += 1;
x++;
}
}
};
what is the final value of counter ? will it be the same for all array objects.
