Possible Duplicate: Why is this code giving an “Unreachable Statement” error? This seems very easy question, I found this question in one book. If anyone help me to figure out why I'm getting error. do { System.out.print("inside do"); } while (false); while (false) { // error System.out.print("inside while"); } System.out.print("outside"); I thought, and according to me, output should be inside dooutside . But, it is showing Compiler Error : Unreachable Statement . Then, I tried to figure out, why, it is showing Compilation error : Unreachable Statement* . So, I change the above code like this

This program I'm making for a COSC course isn't compiling right, I keep getting the error: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 2 at java.lang.String.substring(String.java:1765) at VowelCount.main(VowelCount.java:13) Here's my code: import java.util.Scanner; public class VowelCount { public static void main(String[] args) { int a = 0, e = 0, i = 0, o = 0, u = 0, count = 0; String input, letter; Scanner scan = new Scanner (System.in); System.out.println ("Please enter a string: "); input = scan.nextLine(); while (count <= input.length(

I have the following code: while True: if var_p1 != "0": break else: import random var_p1 = random.randint(-5,5) I want the loop to repeat until var_p1 equals anything but zero. However, I get zero all the time. What am I doing wrong? Answering the question in the title, not the real problem (which was answered by Daniel Roseman): How do you create a random range, but exclude a specific number? Using random.choice : import random allowed_values = list(range(-5, 5+1)) allowed_values.remove(0) # can be anything in {-5, ..., 5} \ {0}: random_value = random.choice(allowed_values) "0" != 0 .

I started learning Java last night, and I'm trying to make my first code without it being dictated to me! It is a simple quiz question that asks the user "Do you think my dog is cute?" If they answer "Yes," the dog Woofs and smiles. If they say "no" He growls at them and frowns. If a different answer is given, "What? Please try again" is printed. I have no issue getting this working so far, but now I am trying to make it so that when an unrecognised answer is put in, the question is asked again, and this repeats until they answer either "Yes" or "No." Here is what I have tried: import java

I have created this function: function promptFile() { while true; do read -p "Please provide a full path [q to quit]: " file if [ $file == q ]; then echo "Exiting.." return 1 fi if [ ! -f $file ]; then echo "File does not exist, please try again" else echo $file break fi done } To prompt a user for file location, ask again if file does not exist, and save the output to a variable if it does, the function is called: tempLoc=$(promptFile) if [ !tempLoc ]; then fileLocation=$tempLoc fi Everything works well unless someone write a bad file location, then the echo is not shown until someone clicks

I have created a loop which will display date 2004 to 2014 in a formatted way. But the problem is, it is showing 204 instead of 2004 and continue this till 209.. So, how to show those year in formatted way, like 2004,2005,2006 etc. Here is the code i have created, tell me where to fix: <?php $yr = 4; while ($yr <= 14) { $x = 1; while ($x <= 31) { echo "$x Jan 20$yr<br>"; $x++; } $x = 1; while ($x <= 31) { echo "$x Feb 20$yr<br>"; $x++; } $x = 1; while ($x <= 31) { echo "$x Mar 20$yr<br>"; $x++; } $x = 1; while ($x <= 31) { echo "$x Apr 20$yr<br>"; $x++; } $x = 1; while ($x <= 31) { echo "$x

I've just started using for loops in matlab in programming class and the basic stuff is doing me fine, However I've been asked to "Use loops to create a 3 x 5 matrix in which the value of each element is its row number to the power of its column number divided by the sum of its row number and column number for example the value of element (2,3) is (2^3 / 2+3) = 1.6 So what sort of looping do I need to use to enable me to start new lines to form a matrix? The command bsxfun is very helpful for such problems. It will do all the looping and preallocation for you. eg: bsxfun(@(x,y) x.^y./(x+y), (1
