Jul 24, 2010 · So just make the "variable name" your key and "variable value" your, ehm, value. Edited because you wanted a Sorted collection: First of all, go for a Treemap instead of a Map. Also, to preserve lexicograph order, normalize your month number padding zeroes to the left, and use "begin" and "end" as delimiters. So you will have:

Aug 17, 2013 · Overall, it is a good loop, but there are a few missing aspects to what I have found in experience to be the best loop. You will eventually want to move to LWJGL or some other java game API, but for now, learn the basics of how game-loops work, and what best suits your needs. Firstly, in answer to one of your points, no.

Being somewhat new to the Java language I'm trying to familiarize myself with all the ways (or at least the non-pathological ones) that one might iterate through a list (or perhaps other collections) and the advantages or disadvantages of each. Given a List<E> list object, I know of the following ways to loop through all elements:

Sep 25, 2015 · You need a for loop. for (int i = 0; i < 3; i++) { // your code goes here } What this does is it initializes a variable called i to 0, then loops while i is less than 3, and adds 1 to i after each loop. This loop should loop 3 times (i = 0: loop, i = 1: loop, i = 2: loop, i = 3: stop loop, since i is no longer less than 3).

If you want to pause then use java.util.concurrent.TimeUnit: TimeUnit.SECONDS.sleep(1); To sleep for one second or. TimeUnit.MINUTES.sleep(1); To sleep for a minute. As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second.

In Java, is it faster to iterate through an array the old-fashioned way, for (int i = 0; i < a.length; i++) f(a[i]); Or using the more concise form, for (Foo foo : a) f(foo); For an

@SebastianH String a ="foo" here "foo" is a string literal and stored in java string pool. if you try to assign same literal into another reference, it will get same reference from string pool. but new string(..) returns a object of string type

Apr 22, 2014 · You could put everything into a while loop like this: boolean isRunning = true; String tryAgain = ""; while (isRunning) { // All your code you have in your example.

Dec 21, 2011 · How do I make a delay in a for loop in java?-1. Java Time Interval. Related. 7. Java - wait and notifyAll ...

The "increment" portion of a loop statement has to change the value of the index variable to have any effect. The longhand form of "++j" is "j = j + 1". So, as other answers have said, the correct form of your increment is "j = j + 3", which doesn't have as terse a shorthand as incrementing by one. "j + 3", as you know by now, doesn't actually ...
