a new Date object initializes to the current UTC date/time.

You can use the Simple Date format to set a time zone, which you get from TimeZone. Then use it to build your formatted date.

If you have two months to make it live, go with php, unless you have lots of experience and can develop an application quickly in java.

More or less, a system which you are interacting with is expecting a square. If you have a number of different developers, say, Bob, John and Sam, who want to interact with this system, they will all...

Just as some applications require a user to intact with it, using a UI; some require interaction with other applications, systems and processes. This is done via an API. in java, an interface defines...

It turned out to be a JSF Lifecycle issue. I have resolved it by creating a new page dedicated to organizing the programmes. Not ideal, it at least it works.

The pagecode (EditProgrammeMatrix) is request; and it is retreiving data from ProgrammeHandler, which is session.

Hi Guys and gals,

I have been banging my head against this wall for a couple days and am coming up to the stage where I just put in an ugly work around, but I would rather solve it and learn...

Try


String.replaceAll(String statement, String replacement)


String (Java 2 Platform SE v1.4.2)

The following is testing if the string variable is null in memory.



str == null



A string variable can exist without any content

49 is the ascii value for the char "1". Java is assuming you want to convert the primitive char into the ascii value of its content.

Your best bet would be to either to read the whole number in...

I was having this problem too, even though I was adding the location to the class path, it was not pickiong it up. Try running the app with the command



java -cp C:\myFolder\ HelloWorld

It looks like you want to replace the / with a new line, have a look at the String.replaceAll(String expr, String substitute) method.

Are you looking for



Thread.currentThread().getStackTrace();


This will return an array of [StackTraceElement]s.

This looks like an issue with what the two methods are returning. If you can't spot anything, try do a system.out of everything which is being returned by each of these methods and confirm it is...

Return a string from your pagecode which matches a navigation rule in your faces config, the serverlet interprites this as a redirection and will load that page.

I'm not entirely sure what you mean, but have a look at what this line is doing, is it ever true?

if(s.charAt(i) <= s.length())

I'm not entirely sure I understand, but I think your best bet would be to draw a little diagram of everything involved and see what needs what.

e.g a Game has many Players and one Board. the...

Have a go at using the examples to call method1, let me know how you go :)

You use the method name, followed by parenthesis "()". You put arguments in the brackets, separated by a comma.

A method is made up of several parts, lets look at:



public void...

You us the method name and argument pattern to refer to it, e.g:



public static void main(String[] args){

//Will work
someMethod("Hello World");

Yes, it will, but the code is testing if it is the number 0, rather than a character, or String containing "0", which is what the method is returning.

When testing the content of a string, use...

if(!rested){
sleep.dream("if statements");
}


Your codes looking good, don't forget to put it into code tags to make it easier to read :)

First of all, you will need to decide what the...

What you could do is create an ArrayList of Player(s), add the first player to the array list. Iterate through the rest of the players and check if their score is greater than the score of the first...

When doing a string compare use the function: String.equals(String)
The reason is a String is an object and "==" is a binary compare. Two different strings which have the same content, are not...

Have a look where you are testing if it is a zero. What does this method return?

See:
String (Java 2 Platform SE v1.4.2)
"
charAt(int index)
Returns the character at the specified...
