//FileName: InventoryData.java
//Prog: Brock Paston
//Purp: To load and search through arrays with binary and sequnetial search.

I'm having some trouble with a code I am writing for class. I had an 2 errors like this before this one and fixed it by changing int avgRe, avgMiles =0; to double. Now I am getting this error and am stuck on what I need to change. Here is the code:
import java.io.*;
import java.util.*;
import java.text.*;
public class Reimbursement_3_09 {
static Toolkit tools = new Toolkit();
public static void main (String [] args) throws Exception {
[Code] ....
This is my error:
[code=Java]
Reimbursement_3_09.java:33: error: incompatible types: possible lossy conversion from double to int
summary (outFile, totalAmount, ctrMiles, ctrMilesgt0, avgRe, avgMiles);
^
Some messages have been simplified; recompile with -Xdiags:verbose to get full output 1 error

I am trying to convert the double 4270571936.0000000000d to a hex string using Double.toHexString() and the answer I'm getting is 0x1.fd17834p31, what does p stands for?
The answer I'm expecting to get is 0x41efd17834000000 so not sure why it won't give me the correct answer?
The following floating point Double to hex calculator shows the write answer right Floating Point to Hex Converter

I need to understand the java Conversion.
I have a char[] containing ASCII characters that need to be converted into int value and double value.
The int value are always stored in 1 char size like 'j'. I extracted it succesffully by converting the char in a ascii bytearray and then used: Integer.parseInt(sb.toString().replace("0x", ""), 16);
How can I get the Value as double when i used the char[] with size 2 or 4 ?
Example : final char[] charValue = { 'u', ' ', '}','+' }; what is the associate Double value ?
Example : final char[] charValue = { 'T', ' ' }; what is the associate Double value ?
Example : final char[] charValue = { 'T', ' ' }; what is the associate int value ?

So, here is the question I have been working on: Write a java class named Time that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example the elapsed time is 9630 seconds, and then the output is 2:40:30 ).Hint: an hour has 3600 seconds and a minute has 60 seconds. Use Scanner class for reading the input.
Here is my code:
import java.util.Scanner;
public class Time {
public static void main(String[] args) {
Scanner scan= new Scanner(System.in);
System.out.println("Enter the elapsed time in seconds:");
int totalseconds= scan.nextInt();
[Code] .....
Now, I know I am supposed to use the remainder operator to figure out the time in minutes and seconds, but the hours has be a little confused. Right now this code compiles but gives me an exception.

This is my program
import java.util.Scanner;
import java.text.DecimalFormat;
public class Lab6 {
public static void main(String[] args) {
int F;
double C = 0;
[Code] ......
output
0 1 2 3 4 5 6 7 8 9
0 degree Fahrenheit equal to :-00.00 degree Celsius
1 degree Fahrenheit equal to :-00.00 degree Celsius
2 degree Fahrenheit equal to :-00.00 degree Celsius
3 degree Fahrenheit equal to :-00.00 degree Celsius
4 degree Fahrenheit equal to :-00.00 degree Celsius
5 degree Fahrenheit equal to :-00.00 degree Celsius
6 degree Fahrenheit equal to :-00.00 degree Celsius
7 degree Fahrenheit equal to :-00.00 degree Celsius
8 degree Fahrenheit equal to :-00.00 degree Celsius
9 degree Fahrenheit equal to :-00.00 degree Celsius
I don't know why the program is not calculating the C degree ?

So i need to write a program that prompts the user for 3 double numbers x, y, z that outputs 2x^3 + 3y^5 + 3x^3y^2 +xyz with
(1) 4 digits precision
(2) with a ',' to separate thousands
(3) all digits of the result including the precision are put to 20 positions (from right to left)
I am not really sure what it is suppose to look like or how to start it.how to mix Math.pow with multivariable and printf.

So I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
Hours: - Population:
0 ------- 1000
12 ----- 2000
24 ----- 4000
I've created the code, but don't understand how to increment hours by 12 and double the population by 2 each time.
public class Population
{
public static void main (String[] args) {
int hours = 0;
int population;
[Code] ....

I just started to teach myself loops. I am trying to convert the while loop into for loops, however somehow I do not get the same printout.
While loop:

public class Test {
public static void main(String[] args) {
int i = 1;
int sum = 0;

Print:
sum is 0 and i is 1
sum is 1 and i is 2
sum is 3 and i is 3
sum is 6 and i is 4

Currently I have socket of the tcp version.
Java Code:
final ServerSocket serverSocketConn = new ServerSocket(9000);
while (true) {
try {
Socket socketConn1 = serverSocketConn.accept();
new Thread(new ConnectionHandler(socketConn1)).start();
[Code] .....
I managed to convert this final DatagramSocket serverSocketConn = new DatagramSocket (9000);
Now I am stuck here
Socket socketConn1 = serverSocketConn.accept();
new Thread(new ConnectionHandler(socketConn1)).start();
Can I use this or I need to create a manual thread pooling for UDP ?

It's probably really obvious, like it usually is, but I can't figure out why I am getting these errors on multiple functions.
if (!client.lowMem) {
for (int l = this.onDemandFetcher.getVersionCount(2), i2 = 1; i2 < l; ++i2) {
if (this.onDemandFetcher.method569(i2)) {
this.onDemandFetcher.method563(1, 2, i2); //Error

The error I get on this line of code is 'Custom may not have been initialized', but no matter what I do, the error sticks.
Custom.cacheIndex = (Custom.cacheIndex + 1) % 10;
final Custom Custom = Custom.cache[Custom.cacheIndex];
//^^^^^

I want to conver String value into Integer, and I have this :
String timeInterval = tfInputTinter.getText();
Integer tint=(Integer.parseInt(timeInterval))*1000;
but when I put this second line, the conversion, the program stops to work. I tried also with Integer.valueOf(timeInterval) but again I had the same problem.

If I type
long z = 0xDeadCafe;
System.out.print(z);
I get a negative number as a result.
But if I append an L to the hex number:
long z = 0xDeadCafeL;
the resulting number is a positive one.
What the difference is between those two lines:
long z = 0xDeadCafeL;
and
long z = 0xDeadCafe;
(same as above, but without the suffix L).
If I don't append the L, is the msb (most significant bit) somehow still carried over to the resulting long variable and in the latter case, where I append an L, it is not and instead the value is filled up with 32 leading zeros (4 Byte difference between int and long)?

I'm having trouble getting the text entered in my JTextField to be converted to the conversion formula. The line I'm getting error in is:
String text = text.getText();
Also I created another JTextField in which I want the answer to be displayed in, but I'm not too sure how to go about that.
This is my attempt at it, but it doesn't work because it doesn't make sense;
result.setText1(Integer.toString(celsius));
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class TempConversion extends JFrame
