"missing return statement" error code

well... i feel like such a n00b... I can't seem to figure out what the problem is with my code, if someone could help me, that would be great. I get an error saying 'missing return statement'. I know that I have some things in here that I don't need but I will need them as I go on making this program.
with this code:
import java.io.*;
import java.math.*;
public class Tester
     public static int time = 0;
     public static void main(String[] args) throws IOException
          System.out.println("Welcome to the 2008 Java Games!!!");
          time=1000;
          delay(100);
          //Method Name: delay
          //Method Arguments: used to wait for a given time
          //Goal of Method: Delay for a given time
     public static int delay(int time)
          try {
               Thread.sleep(time);
          catch(InterruptedException ex) {}
          time++;
}

What does the error say? "Missing return statement"? Then I'm going to venture a guess and say that you're missing a return statement. If you don't know what a return statement is, then you have some learning to do:
http://java.sun.com/docs/books/tutorial/java/javaOO/returnvalue.html
Read that, then look at your delay() method and how you call it. And notice that you've made delay() of type "int".
Edit: Or just have someone else give you the answer :P

Missing return statement error! HOW?

Why would the following code complain that it's missing a return statement, yet there are more than 4 return statements. All the possibilities are captured on the if statements and there are no more possibilities.
public static double power(double b, int e)
        if(e == 0 || b == 1)
            return 1;
        else if(e > 0)
            if (b > 0)
                return b * power(b, e - 1);
            else if (b % 2 == -1)
                return -(power(b, -e));
        else if(e < 0)
            if(b > 0)
                return 1 / power(b, -e);
            else if (b % 2 == 1)
                return -(1 / power(b, -e));

ejp,
Thanks for the rapid response
I thought there could only be these possibilities:
1. e = 0 and b = 1
captured in the 1st if statement
2. e > 0 and either (b > 0 or b < 0)
captured in the second if
3. e < 0 and either (b > 0 or b < 0)
captured in the Third if
and else nothing else+
What's remaining? This was meant to be easy, what the hell am I not seeing?
flounder Thanks too for your response.
I tried to remove the if on the last else if (below) but still got the error
else
            if(b > 0)
                return 1 / power(b, -e);
            else if (b % 2 == 1)
                return -(1 / power(b, -e));

}It says i am missing the return statement,but i do have set return something,whats the error? thx for helping

For example, what happens if the SQL query doesn't
return any rows, and rs.next() is never true?The while() loop will be skipped and the if statement
will execute, which has two branches, one of which is
guaranteed to return?Oops. My bad.
I thought the ifs were inside the while.
Okay, the problem here is with the exception handling. Catching and logging and doing nothing else is usually almost as bad as just smothering them. In this case it's especially true because the method then just continues after the catch blocks, in which case there's no return.
You have to actually handle the exceptions if you're not going to propagate them. In this case, that would mean returning some reasonable default value. I'd say that's not a good idea here, and you're better off to just let the exceptions be thrown, or wrap and rethrow in your own exception.

Missing Return Statement, where do I put it?

Hi am using some code from the Sun website, it is called the KnockKnockProtocol, and I have edited it a bit and I get a "missing return statement" error. When I put one in the server does not run at all?

Missing return statement question

I got a missing return statement error when i compile in this code but however i dont get any missing return statement errors in the second code that i pasted here.. What is the difference i didn't get it ? Thank you.
public class primechecker {
    static double remainder = 0;
    public static boolean primecheck(int number){
         for(int i=2; i<number; i++){
              remainder = number % i;
              if (remainder == 0){
                   return false;
         if (remainder !=0){
              return true;
    public static void main(String[] args) {
         System.out.print(primecheck(10));
}That is the second code which gives no error.
public class positiveornegative {
   public static boolean numbercheck (int number){
     boolean booleann = true;
     if(number > 0){
         return true;
     else if (number < 0){
         return false;
     else {
          return false;
    public static void main(String[] args) {
         System.out.println(numbercheck(-2));
}

In your first snippet, the compiler has no guarantee that the for loop will be executed at all. That leaves only one return inside an if condition which again it has no guarantee that it will ever be reached(the if test may fail). This leads the compiler to the conclusion that your method may never return anything at all. Yet it's definition says that it must return a value.

Missing Return Statement Hell!!

Missing return statement? News to me!

Before I ask anything let be begin by saying thanks to all you people that help others on these boards, I've never posted a question before but I have often found the answers to my problems somewhere here. I'm currently working on one of my last java assignments ever and I am completely stumped as to whats going on. All I want out of this code is for it to read a txt file for a bunch of phone book entries, load them into some arrays, then sort them by first name, last name, then phone# then return the array so I can use it later on. I've got the entries loaded, I've got em sorted, but I can;t return it. When I try I get a missing return statement error. I dont know why its not returning the array, so I thought I'd ask the pros. I can get it to work fine if I dont return anything but what good is that eh?
Please forgive my terrible coding, I am in no way a real programmer, I just want to pass my classs and never think about it again 8) any help would be appreciated. Tis is built to work with an "Entry" file, if you guys need it to proceed lemme know and I will post it. Thanks.
the code....
    public class CSCD210PhoneBook {

               Entry[] array=null;
     array=populateEntry(entryCount, fileScanner, kb);
      }//end main array=

                     fileScanner.nextLine();
                     lineCount++;
               entryCount= lineCount/8;
               Entry[] array=new Entry[entryCount];
               fileScanner.close();
               fileHandle = new File(fileName);
               fileScanner = new Scanner(fileHandle);
                    for(int i =0; i<array.length;i++)

if (array[indexSmallest].compareTo(array[curPos]) > 0)
indexSmallest = curPos;
} // end for
temp = array[start];
array[start] = array[indexSmallest];
array[indexSmallest] = temp;
               return array;
Any help would be most appreciated.

The code you posted has mismatched braces: it needs another } at the end.
Linked with this is how - or rather when - you return array from the populateEntry()
method. You have a couple of nested for-loops and you return array inside (at the
end of) the outer loop.
The compiler is really fussy about making sure that an Entry[] is returned from this
method. If you outer for-loop never gets executed for some reason, then the return
statement will never be reached. The compiler won't accept this.
Either
(1) move the return statement outside both loops so it is always executed. This
appears to be the most logical thing - but I haven't read your code that closely. It's
just that having return at the end of a for-loop (with no "continue" in sight), doesn't
make a lot of sense.
or
(2) add another return after both loops have finished.

Doubt on Return statement

Hi,
IN the code below,
I need to return a Double value. That Double value is declared and calculated with in IF condition.
But, If i keep return statement with in if condition, i get "MIssing return statement error". IF i keep Return statement outside if(), I get "symbol c not found error".
How do i fix this?
private Double calculate(Double a, BigDecimal b) {
        if(!((null == a)&&(null == b))){
        //do some calculation
        Double c = Double.valueOf(b.doubleValue());
        return c; ---> Getting error right here. (Can't find symbol c error.)
   } please help

Is there any solution for this?Perhaps you need two return statements.This depends whether <tt>a</tt> and <tt>b</tt> can be null because of business rules or programming errors.
If the latter I'd not care for the NPE or just throw my own NPE from the else path telling which parameter has been null .
If business rules forcs you to handle null values these rules must provide a solution for that case to be implemented in the else path.

UDF missing return statement }

Hi,
I'm wondering how the missing return statement error can be avoided in this code, I've tried all sorts of syntaxes but it just won't work:
public String DetermineCostCenter(String KTOS,String KTOH,String FNR,String KST,Container container){
int KTOHNR = 0;
int KTOSNR = 0;
KTOHNR = new Integer(KTOH).intValue();
KTOSNR = new Integer(KTOS).intValue();
if (KTOSNR > 6999999 || KTOHNR > 6999999) {
                     if (FNR.equals( "1"))
                              return "1008590";
                    else if (FNR.equals("2"))
                             return "5008090";
                    else
                            return " ";
if (KTOSNR > 6999999 || KTOHNR > 6999999)
     return KST;
if (KTOSNR < 3000000 && KTOHNR < 3000000)
     return " ";
Thanks
Tom

Try this...
int KTOHNR = 0;
int KTOSNR = 0;
String tmpktosnr = "";
KTOHNR = new Integer(KTOH).intValue();
KTOSNR = new Integer(KTOS).intValue();
if (KTOSNR > 6999999 || KTOHNR > 6999999) {
if (FNR.equals( "1"))
tmpktosnr = "1008590";
else if (FNR.equals("2"))
tmpktosnr = "5008090";
if (KTOSNR > 6999999 || KTOHNR > 6999999)
tmpktosnr = KST;
if (KTOSNR < 3000000 && KTOHNR < 3000000)
tmpktosnr = " ";
return tmpktosnr;
Hope this will help.

Unreachable statement error occured while using return statement.

Consider this code
class q25{
     public static void main(String args[]){
          amethod(args);
     public static void amethod(String args[]){
          String str;
          try{
               str = "Hello "+args[0];
               System.out.println(str);
               System.out.println("Returning to caller");
               System.exit(0);
          catch(Exception e){
               System.out.println("Exception ocured");
               System.exit(0);
          finally{
               System.out.println("In finally");
          System.out.println("At the end of method");
}Above code compiles and runs successfully without any errors.
Now consider below code which is same as above one except "System.exit(0)" statements were replace by "return" statements. Below code when compiled gives error as
"q25.java:22: unreachable statement
System.out.println("At the end of method");
^
1 error"
One thing i didn't understood in this context that, the above code when compiled should get same error as stated above. But not. It is obvious that presence of System.exit(0) must generate unreachable statement same as when it is replaced by "return" statement. What is the difference in getting the error for above but not for below code. Pls anyone help.
class q25{
     public static void main(String args[]){
          amethod(args);
     public static void amethod(String args[]){
          String str;
          try{
               str = "Hello "+args[0];
               System.out.println(str);
               System.out.println("Returning to caller");
               return;
          catch(Exception e){
               System.out.println("Exception ocured");
               return;
          finally{
               System.out.println("In finally");
          System.out.println("At the end of method");
}

Since you have a "return" in both the try and the catch portions of the try/catch block *(the second of which you should never do)* , anything thing that comes after the try/catch/finally blocks will be unreachable.That is not true. There are plenty of reasons to return from a catch block. If you handle the exception instead of rethrowing it or another exception, then you'll need a return somehow, either there or after the catch block. What you should never do is "return" in a finally block, because that will mask any exception in flight about to be thrown to the caller.Perhaps masijade's use of never is too strong, but I too prefer/tend to avoid using return anywhere in try/catch/finally to avoid potential gotchas. Consider:
public class TryCatchFinally
public Data process(String s)
    Data returnData = new Data();
    try
      returnData.value = Integer.parseInt(s);
      returnData.message = "Success";
      return returnData;
    catch (Exception ex)
      returnData.value = -1;
      returnData.message = "Fail";
      return returnData;
    finally
      returnData.value = 42;
      returnData.message = "?";
public static void main(String[] args)
    TryCatchFinally demo = new TryCatchFinally();
    Data d = demo.process("2");
    System.out.println(d.message + ": " + d.value);
    d = demo.process("2.1");
    System.out.println(d.message + ": " + d.value);
class Data
    int value = 0;
    String message = "";
}

This should work? error missing return statement.

Why do I get this error?
missing return statement
To me the code seems good?
public SortAbstractProduct createSorter(String whichAlgorithm) {
if (whichAlgorithm.equalsIgnoreCase("BubbleSortProduct") )
System.out.println("from scf buublesort check");
return new BubbleSortProduct();
if (whichAlgorithm.equalsIgnoreCase("OptimsedBubbleSortProduct") )
System.out.println("from scf optimesed buublesort check");
return new OptimisedBubbleSortProduct();
if (whichAlgorithm.equalsIgnoreCase("QuickSortProduct") )
System.out.println("from scf Quicksort check");
return new QuickSortProduct();
}

You need to retrun an object of SortAbstractProduct, yet your are trying to return 3 different types(BubbleSortProduct, OptimisedBubbleSortProduct, QuickSortProduct). These need to be subclasses of SortAbstractProduct, then you will be able to cast them it.
