I am having issues with these error messages.... I have tried a couple of different things with each error but haven't been able to figure it out.

I want to convert a date which can be of any date formats into yyyy-mm-dd format...My code is below.
String[] date_formats = {
"MM/dd/yyyy",
"dd/MM/yyyy"
,"dd-MM-yyyy",
};
String dateReceived = "13/11/2012";
for (String formatString : date_formats){
[Code] .....
I have a piece of code as below for date format conversion.
DateFormat formatter1 ;
DateFormat formatter2 ;
Date date = new Date();
formatter1 = new SimpleDateFormat("yyyy-mm-dd");
date = formatter1.parse("1952-12-10");
System.out.println("before format, date is " + date);
formatter2 = new SimpleDateFormat("dd-MMM-yy");
formatter2.format(date);
System.out.println("after format, date is " +formatter2.format(date));I would like to change 1952-12-10 become 10-DEC-52, h
However, I am getting below output:
before format, date is Thu Jan 10 00:12:00 MYT 1952
after format, date is 10-Jan-52
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000"

I have a requirement to convert 'unix time stamp' to 'Date time format'

I am working on a program that will allow a user to input grades for a class of four students who have taken two tests. Based on the grades entered, the program will calculate the averages of the two tests for each student and display it along with their respected letter grades.
Now I can get the program to compile successfully, but after inputting the grades in, I get the error message saying that it cannot format given object as a number. I am using 4 arrays to execute this program and maybe that's why I'm having the trouble? I'm not sure because I am still fairly new at this stuff and can't sen to resolve it.
I was having problems for a while and then finally got excited when I got it to compile without any errors and now I'm getting an error inside my program. All I need to do is format the numbers of the grades into something like: 000, and each of the averages as 000.0. I understand how to do it because I have done it in another program I've done in the past. I just don't know how to fix this error that is coming up.
here is my code:
import java.util.Scanner;
import java.text.DecimalFormat;
public class TestAverage
{
/**
* A program that will store and process 2 test scores for a class of 4 students.
* The program will prompt for the test scores as shown above in the sample run.
* After all the data is entered,the program will display the score for test 1, test 2 .
* The average of the 2 tests and the letter grade for the class for each student in a tabular format.

I'm making a program that can read an input of English or Morse code and return an output of Morse code or English back. The English-->Morse works fine, but not Morse-->English. I'm pretty sure my solution lies in displaying the variable 'morseWord', but no matter where I put it, I always get an error saying the variable has not been initialized. Here's what it looks like now:
import java.util.Scanner;
public class pro1
{
static final String[] alpha = {"a", "b", "c", "d", "e", "f", "g", "h", "i",
"j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u",
"v", "w", "x", "y", "z", " "};
static final String[] morse = {".-", "-...", "-.-/>/>.", "-..", ".", "..-.", "--.", "....", "..",
".---", "-.-/>/>", ".-..", "--", "-.", "---", ".--.", "--.-/>/>", ".-.", "...", "-", "..-",

I'm getting a NumberFormatException while executing the below statements.
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day_of_month = 15;
long m_time = Long.parseLong((month + 1) + "/" + day_of_month + "/" + year);
and
long m_time = Long.parseLong(String.valueOf((month + 1) + "/" + day_of_month + "/" + year));
I'm doing this project in JSP.net, with html. and in one of the web pages, what I'm doing is that, a person is transferring an amount to someone else, and if the transfer amount is more than the account balance, then he cannot transfer. else, save details in a table.
Here's the code I've used
<%
String t1=request.getParameter("text1");
String t2=request.getParameter("text2");
java.util.Date date1 = new java.util.Date();
SimpleDateFormat ft = new SimpleDateFormat ("dd/MM/yyyy");
int tamt = Integer.parseInt(t2);
int bamt = 0;
[Code] .....
But when i enter the fields and click the submit button in the form, to save it in the table, i get the error:
"org.apache.jasper.JasperException: java.lang.NumberFormatException: null"
(I've attached a screen shot of the error) : NumberFormatException.bmp (750.98K)
What does this mean? how do i find the line in the code that has the error?
Everything is working great except for my back button at line 172. It works good but if I try to click the "insert" button again. It gives me the java.lang.NumberFormatException error. Other than that it works fine, the "insert" button still works.

This is giving me NZEC exception.I am testing this solution on a online judge.So I don't have any TestCase in which this is failing. So, what are the possible reason of NZEC exception in my code?

So I'm learning java having been using c#. I based this code off an example from class. It compiles fine with no errors, but I'm getting this:

I am getting a nullpointer exception after "cleaning" up my code by putting repetitive stuff in a method.
The error points to this: ai.getItRight(n, answer);//make sure the user enters yes or no..
The error occurs at lines 19 and 25.Here is the relative code:
public boolean AskQuestions(Node n, String yesOrNo, String answer, String question){
if(yesOrNo.equalsIgnoreCase("no") && n.getRight() == null){//i guessed the wrong answer
System.out.println("I give up. Who is it: ");
answer = input.nextLine();
[code]....
My previous code, which use to have the contents of getItRight in place of lines 19 and 25 worked just fine. So why am I getting this error? I dont want my methods to be crazy big like how they usually end up.
int x = 10;
do{
System.out.print("value of x : " + x );
x++;
System.out.print("");
}while( x + x == 22 );
When i put x+x==22 than it gives 2 values of x which are 10 and 11, they are wrong but when i put any other value like x+x==24 it just shows 1 value which is 10. I am not able to understand what mistake is there. I have been searching it for past whole month but didn't got any reason.
I am having errors but not sure why.

So I want to know how in Java you can pass a unkown type into a method (type can be an int, double, or a user defined object) and return that unkown type.
example of what I want:
Java Code:
public (unknowntype)[] method2 ((unknowntype)[])
//Process Data
//unknowntype.process();
return (unknowntype);
} mh_sh_highlight_all('java');
I know in C you can use void pointers and in c++ we have templates but I do not know how java handles this. Also I want to know if it is possible to call a method in the unknowntype.
I'm a independent IT contractor. On 2 systems this week I've experienced an issue when attempting to download JAVA the file is of an unknown type in IE. See attached. Alternative browsers on the same machine function properly.
