Unreachable statement or declaration

I don't know why i'm getting this error. I looked up the error on the Sun site and it says that you get this error when you have code below a return statement like
return x
int x=5
but i don't have anything like that going on in my code heres my code below. The error is coming from the return playerscard line at the very end of the code. Any help at all would be really appreciated. Thanks

Within a given block, once return is called, the rest of the code in the block will not get executed (since the thread of control "returns" to the caller) and is thus unreachable.
Since your two return statements are in the same block - in this case a method - the second return (and, in fact, anything after the first return) is unreachable.
However, you can do something like:
public String example( int a ) {
   if( (a % 2) == 0 ) {
        return "Even";
   else {
        return "Odd";
}In this case, we have code after the first return. Note that the most narrow block in which the return "Even"; statement appears. It is an if statement, not a method. The return is the last statement in its block. The remaining statement(s) (the "else" block) is still reachable when a mod 2 equals zero.
If you need to return multiple values, create a new class and return an instance of that class.

Problems with booleans - Unreachable Statement.

Hey,
at the top of my class I have Random() declared like so...
private static Random noise = new Random();
and further down I'm trying to do an IF statement like so....
if(noise.nextBoolean() == true)
makeBetterSB.reverse();
the IDE displays an error of "Unreachable Statement".
What have I done wrong?

We would have to know which statement the compiler said was unreachable to answer that. We would also have to know what comes before that statement, because it's the code before that statement that causes it to be unreachable.

You have to create stored procedure in SQL only .
Like u must have create for Crystal .
You can execute procedure in query manager but you have to enter parameter manually..
example
Exec @Test '20140101' '20140501'
Every time user has to enter it manually in yyyymmdd format in case of date parameters.
Example
Create Proc [@Test]
as begin
DECLARE @name AS date
Declare @name2 AS date
/* SELECT FROM [2013].[dbo].[OINV] T0 */
/* WHERE */
select '2013',t5.U_salmannm,t1.CardName,t2.sumapplied as CollectionAmount,t2.DcntSum ,t3.DocTotal as InvoiceTotal,

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[]){

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

      returnData.message = "Success";

State tax declaration for Mexico

Hello all
We are trying to obtain the report for the State tax declaration on Mexico, but we have some troubles with one state (Veracruz), if I run the report for some months of 2010 it shows me the text "There are no data for the selection conditions", obviously we have the payroll for those months, and we have employees for that state. Does anyone know why we cannot see results for all months?
Thank you in advance.

We found a configuration error on Infotype 0561 date for our employees.

Expected "unreachable statement" error but it compiled successfully

Bellow following code, i expected compile time error something like "unreachable statement i++" on line no. 4 as it is obvious that the line returns 'i' and increments 'i' value due to virtue of post increment operator ++. But i didn't get any type of errors - compile time or runtime error - which i thought would get one and ran successfully printing 0.
Can anybody explain the reason behind this?
1. class Target {
2.     private int i = 0;
3.     public int addOne() {
4.          return i++;
5.     }
6. }
7. public class Client {
8.      public static void main(String[] args) {
9.          System.out.println(new Target().addOne());
10.     }
11.}

karthikbhuvana wrote:
Ok fine. That's a good example. But my question is, once the control returns from the method addOne(), how it is possible that variable 'i' gets incremented?
return i++; is equivalent to the following:
int tmp = i;
i = i + 1;
return tmp;The expression i++ is evaluated completely, and then the value of the i++ expression is returned. Evaluating i++ completely means "remembering" the current value of i as the value of the expression, and then incrementing i.
That's also why
int i = 0;
i = i++; // never do this for real
System.out.println(i);prints out 0, not 1. The RHS is evaluated before assigning to the LHS. The "post" in "post-increment" doesn't mean "after the rest of the statement is done." I means "increment happens after getting the value of the expression."

Tip: You will find the appropriate method in the Java API. (If you are not familiar whit that try http://java.sun.com/javase/6/docs/api/)
If you do not find the answer just ask again... Everybody loves to help here it seems. But you should know that the sooner you learn how to find the (simple or not simple) answers in the API the sooner you will be a real good java programmer. good luck!

What does unreachable statement mean?

I'm trying to write an Exception to prevent a denominator in my program from being 0.
public String toString()
        return num + "/" + denom;
        if(denom == 0)
            IllegalArgumentException exception = new IllegalArgumentException("fractions must not have denominators of zero");
            throw exception;
    }But all I get is unreachable statement.

Ah that makes sense then, I'm a bit confused where I'm meant to put the code then, I'm carrying out 4 different operations on the fractions (add, subtract, multiply, divide) I need to ensure that the denom isn't a 0, so would I be best creating a method that tests for a zero Yes. Follow the DRY principle: Don't Repeat Yourself. If you find yourself writing the same code in several places, put that code into a method.
and then calling that at the end of each of the 4 operations and then throwing an exception if the answer is incorrect?No. Why would you do it at the end? You have to do it at the beginning. When you return, the method ends, and nothing after the return statement is executed. That's why you get that exception, as people have been explaining.

SQL Server XQuery: Sequence Expression - What is @x in the code statement of DECLARE @x xml; ? What is N in the code statement of SET @x = N ' '; ?

Hi all,
I did the basic stuff of T-SQL long time ago. I dive in to do the SQL Server XQuery programming. I saw the following set of code statements from a tutotial website:
DECLARE @x xml;
SET @x = N'';
SELECT @x.query('(1,2,(10,11,12,13,14,15)),-6');
1) What is @x in the code statement of DECLARE @x xml;? What is N in the code statement of SET @x = N ' '?
2) Is the N in the code statement of SET @x = N ' '; absobutally necessary in the SQL Server XQuery programming? From XQuery Language Reference of SQL Server 2012 Books Online, I saw the following set of code statements:
DECLARE @x XML
SET @x = '<a/>'
SELECT @x.query('if (/a[1]) then "true" else "false"')
go
I wonder why there is no N in the code statement of the XQuery Language Reference?
Please kindly help, clarify my confusions and answer my questions mentioned above.
Thanks in advance,
Scott Chang

@x is a variable with xml data type. An N prefix stands for the string in Unicode. The N is not necessary in the SQL Server XQuery programming if the values of the element or attribute in the xml are not in an international language.

Wrong code analysis on "unreachable statement" for nested loops

Try this with JavaFX 1.2 (NetBeans 6.5.1)
function foo():Void {
    for (i in [0..<10]) {
        for (j in [0..<10]) { // be marked as unreachable statement
            if (match()) {
                break;
            return; // I just want to get out
        // break goes here
}It shows "unreachable statement" at the second 'for'.
Right now I just change "return;" to "if (true) return;" to get it pass.

I agree it is a bug at the compiler level. If I do your change and add println of i and j, I get a trace on j, obviously.
You should file a bug report at [Jira / Kenai|http://javafx-jira.kenai.com/] (or I can do if you don't want to create an account).
[EDIT] Uh, no, it is a known problem: [Bogus 'Unreachable statement' error|http://javafx-jira.kenai.com/browse/JFXC-3323], I will add this thread as a comment.
A more complete use case:
function foo(): Void {
     for (i in [ 0 ..< 5 ]) {
          println("I {i}");
          for (j in [ 0 ..< 5 ]) {
               println("J {j}");
               if (match()) {
                    break;
               println("Some operation in the inner loop");
               if (true) return;
          // break goes here
function match(): Boolean { return Math.random() > 0.5; }
foo();Now, the inner loop isn't really necessary, we never go beyond 0 for j... But technically, there is no unreachable statement, unless it means we never go up to 5 in the inner loop. In this case, Robert Field is right, the error message should be clearer.

When you throw an exception, the program flow never continues "normally" on the next line --- control is always transferred to the nearest exception handler. Thus control never reaches the break statement on the same line, and "unreachable statements" like this are illegal in Java.
Solution: remove the unnecessary "break;"

How to ignore unreachable statement (javac)?

for debugging/testing purposes, i would like the javac compiler to ignore unreachable statement or just print a warning and not an error. is this possible?
reason: it's much easer to type "return result;" somewhere within code than do enclose several (cascaded) parts with if ().

Good day,
Even though I'm pretty new to Java, I don't think this is possible.
I would presume that you're doing this mainly to debug your code.
I personnaly define a boolean variable, which can be accessed all throughout the class file : "boolean leavenow=true;"
When I want to insert a "temporary breakpoint" to check things out, I simply type something like "if (leavenow) return result;".
I understand that this is tad longer to type, but it doesn't affect the indentation of your code if you want to keep the things "aligned".
Might not be the ideal approach, but this is a way to look at it.
Regards.

Unreachable statement

Hi experts,
After running the Extended check (SLIN) I got the following message:
Unreachable Statement After Jump Statement EXIT:
DESCRIBE TABLE i_table LINES itab_lines.
(You can hide the message using "#EC *)
My question: How can I eliminate this error?

Hi...
If u have any statements that terminates the Current processing Block / Program such as
Leave to Screen...
Exit..
Stop..
Then any statements after them will not be reachable.
So you need to avoid them.
Paste ur code if u are not able to trace it.

Unreachable Statement in Simple Boolean Method

I cant figure out why return false; cant be reached. I have a similar method right above and its fine. Any help is greatly appreciated.
    public boolean equals(SNode n, SNode m){
         if (n.equals(m));{
              return true;
        return false; //<----- Unreachable Statement, why?

// this
if (n.equals(m)); {
return true;
// is equivalent to this
if (n.equals(m)) { /* do nothing */ }
{ // block that gets executed regardless of the if's results
return true;
}Get rid of the semicolon after the if.
