Java SE, Desktop, The ATM would probably be in Java Web Start

loool , Did you watch the vid above? JDK 8 is going to be revolutionary

Hmm ok cool,

Implement using iteration recursion a substring generator that generates all the substrings of a string. For example, the substrings of the string "rum" are the seven strings

"r", "ru", "rum", "u", "um", "m", ""

Goodluck

Challenge
Your task is to implement using iteration recursion a method that checks if a string is in a larger string, i.e a substring in a string.
Given the word "Mississipi" and a String 'sip', your method should return true.

Further more, implement an integer method that returns the starting position of the smaller string, in this case, sip. So in total, given the above inputs you program should print

true
6

Goodluck.

c'mmon guysssss

sorry guys, removed d lame past,

take a look at this http://blogs.oracle.com/java/entry/moving_java_forward_a_video

Java is never gonna fall. Its just the best

wen we get to the specification phase, we would settle all that

lol, thats like the main stuff i do apart from developing,

Yaay! thanks that worked!
So which is real, user and sys. What does each calculate

Hmm doesn't linux have ym? or what chat app do u use on linux

Even if you have the time and fully focused?.trst me u wud except if you hate maths which I doubt

Obviously, hhaha was just kidding, but i can tackle 10 in 3hrs.am sure of that

All my permutations are in a list Just take out the for-loop in the main method and the ArrayList permutations is your list,

public static void main(String[] args)
	{
		PermutationGenerator generator = new PermutationGenerator("eat";
		ArrayList<String> permutations = generator.getPermutations();


	}

Y arent u online(YM)

Hmm ok cool, what language are you expected to implement it in? Do you have a specification or requirement?

Yeah sure, would be much easier if i just carpet bomb the code with comments, Before that, give me your own algorithm for checking if a string is a palindrome. What would you do, it doesn't matter if you can but it helps to have a solution in mind, Aiit am waiting, Do that while i bombad the code,

hmm cool

A java solution

class Palindrome
{
	private static String currentString="Madam i'm adam!";
	
	public static void main(String[] args)
	{
		System.out.println(isPalindrome());
	}
	
	static boolean isPalindrome()
	{
		return isPalindrome(0, currentString.length()-1);
	}
	
	static boolean isPalindrome(int start, int end)
	{
		if(start >= end){
			return true;
		}
		
		char first  = Character.toLowerCase(currentString.charAt(start));
		char last   = Character.toLowerCase(currentString.charAt(end));
		
		if(Character.isLetter(first) && Character.isLetter(last))
		{
			if(first == last){
				return isPalindrome((start+1), (end-1));
			}else{
				return false;
			}
		}
		else if(!Character.isLetter(first))
		{
			return isPalindrome((start+1), end);
		}
		else
		{
			return isPalindrome(start, (end-1));
		}
	}
}

Again its coded the OO way for reuse so it could be much shorter,

Noone would just write a whole software for you. Are you stuck with something?

its today!!!!!!!!!!!!!! cant wait for the live show

Am not 100% sure but i think its not the site that sends the application but the application you integrate into it. If i were to do something like this, Java web start would be my first choice. So what experience do you have with software development

Hehehe do you want to go on a ride? Am gonna find a way to login to euler again(cant remember my password) and solve 40 questions in the next 5hrs , LOL On a serz note if i sit down with those questions,  i wud brutalize them. You are right, the reason why i dnt like it is because of the "submit answer" thingy,  no code testing or anyfin, time limits and the rest.

It just makes me lazy and i dnt even try to work on my code more than 2wice. Say i try to find the 12345678th fibonacci number, if i do it first with a loop, and then try to play with recursion. Thats where i just stop because I know i just need the answer. Computer Scientists are lazy people, even tho they actually aren't.

Is that it?

tundebabzy:
hahaha. This is a project euler question

So i heard I have a document filled with some terrible questions, these are the easy ones on the document, lmao

HAhaha naa was just asking if you tried it. Its too easy for u so might not even bother testing. Do the compilers come installed with linux? Cause i kinda like have ll compilers here waitin, Mac is just the best .lol How about calculating the program run time, ?

Nooo its not man,  No one times u, Nothing you just provide the answer.No time frame. hahhaa You probably wanna take a look at the real programming challenges,

I left that project euler after 20 problems cause its all maths, no berra challenge

I only understand halft of that code tho. Does it work? I mean dd you try the sample input?

hahaha yeah i type faster than my static keyboard now adays(effects of recursion), Was asking for the syntax for getting the run time of the program

could you just state some things you have done in the past? No need for proof but be honest so we know what else we need to commence full development.

Yeah it wud and yope the brute force,  I use a Mac, wats d syntax? or rather how o i go about it, I normally use my text editor(TextMate).
