Is the while-loop advantageous? List<String> names = Arrays.asList("John", "Jeff", "Mary", "Elise"); //for-each loop for(String name: names){ log(name); } //traditional for-loop for(int index=0; index < 10; ++index){ log(names.get(index)); } //Iterator while Iterator<String> iter1 = names

I've looked at the code here as well as the code here but I still can't seem to get my code to work right. With the 2nd link, I can get a "timer" that counts up on the page, but with the first, my UI locks up. What I'm trying to do is have a seperate thread that continually flips the text in a textswitcher every 3 seconds as long as the app is open. I need it to switch between two values, and have tried something like the following: private Runnable mUpdateTimeTask = new Runnable() { public void run() { while(true){ try { mHandler.post(new Runnable(){ @Override public void run() { try {

In short, I'm utilizing C# to scientific computation and I've written a method that has a while loop that may run to a user-specified quantity of steps... Actually, this method may take too long to execute (like more than 5 hours). When it takes this long, I may want to stop the method pressing Esc key, for example. As I read something about breaking while , it is as simple as a Boolean flag or something like this. So I thought in something like this: public Double? Run(int n) { int i = 0; while ((i < n) && (/* inputkey != ConsoleKey.Escape */)) { // here goes the heavy computation thing //

I am a beginner with Python and trying few programs. I have something like the following WHILE loop construct in Python (not exact). IDLE 2.6.4 >>> a=0 >>> b=0 >>> while a < 4: a=a+1 while b < 4: b=b+1 print a, b 1 1 1 2 1 3 1 4 I am expecting the outer loop to loop through 1,2,3 and 4. And I know I can do this with FOR loop like this >>> for a in range(1,5): for b in range(1,5): print a,b 1 1 1 2 .. .. .. .. // Other lines omitted for brevity 4 4 But, what is wrong with WHILE loop? I guess I am missing some thing obvious, but could not make out. Answer: The corrected WHILE loop.. >>> a=0 >>>
