Void and boolean

public void boolean compute(int n)
{ if n>5
     {return true; }
     else
   {return false; }
}Is this subroutine possibly correct?
Is there any possibility for a subroutine to have void and boolean at the same time (not to mention an if without parentesis)??
Thank you

What do you mean "void and boolean at the same time"?
If it compiles, then it's guaranteed to return a boolean value (unless it throws an exception, or the VM shuts down or something). The compiler is quite anal about that.
A simpler way to write it would be public void boolean compute(int n) {
return n > 5;
} But then, you don't exactly need a method for that, do you.
The if without parens will not compile.

Difference between void and null?

wht is da difference between void and null w.r.t java?

Why do you care, unless you're implementing a java compiler or JVM?Wow, you sure do suck at helping out in a forum. Why even make this post? You're not helping the OP any, and you made yourself look like a tool.
To the op:
Null is java's version of a null value. Java's version is more strict then many other languages, and will not work in a boolean expression or anywhere code expects a real and not null value. It's simply null.
Void is java's way of declaring no return type on a method. Methods that are void take no 'return' statement and if one is provided will cause a fatal error. The exception to this is using 'return' without a value, which returns control to the caller of the method.
Observe:
//this method returns an int
public int return_int(){
    int value = 5;
    return value;
//this method does not return an int
public void return_nothing(){
    int another_value = 123;
    System.out.println("Here's the value: " + return_int());
//this method does not return anything
public void nothing_returned(){
    return_nothing();
    return;
    System.out.println("This line never gets printed; the method returned control already!");
}

Don't put all your faith in Schrodinger....
I repeated the "Schrodinger Cat" experiment, and
could determine whether the cat was alive or dead.
It was a function of time. After 4 or 5 days,
s, the outcome was deterministic.Schr�dinger's Cat is bad OO. The cat does know its
state, and that info should remain encapsulated. If
you need it, you can still reference the animal and
query it.Wouldn't the cat's state be more like a variable that has only been declared but not initialized? :^)

Difference between false and Boolean.FALSE ?

Hello,
can you please tell the difference between false and Boolean.FALSE ?

The trap behind autoboxing is that things work just fine when at least one side of the equation is a primitive. Things turn out unexpected when all of a sudden both sides of the equation happen to be an object:
public class Test {
     public static void main(String[] args){
          boolean bp = false;
          Boolean bo = new Boolean(false);
          Boolean bo2 = new Boolean(false);
          System.out.println("Primitive VS Boolean.FALSE: " + (bp == Boolean.FALSE));
          System.out.println("Primitive VS new object: " + (bp == bo));
          System.out.println("New object VS Boolean.FALSE: " + (bo == Boolean.FALSE));
          System.out.println("new object vs new object 2: " + (bo == bo2));
}Result:
Primitive VS Boolean.FALSE: true
Primitive VS new object: true
New object VS Boolean.FALSE: false
new object vs new object 2: falseTry explaining that in the context of this thread without ever referring to autoboxing specifically. Remember that people find these posts through Google, if you pass out information while hiding the gritty details, it gets confusing.

Void and Cancelled Checks

Hello All,
What is the difference between void and cancelled checks?
Thanks,
Deki

A voided cheque is one where the cheque number is marked as void but the payment document still exists. For example if a cheque was torn and you want to assign the payment to a different cheque.
A cancelled cheque is when you did not intend to make that payment so you void the cheque and reversed the payment.

Difference between public void, private void and public string

Hi everyone,
My 1st question is how do you know when to use public void, private void and public string? I am mightily cofuse with this.
2ndly, Can anybody explain to me on following code snippet:
Traceback B0;//the starting point of Traceback
// Traceback objects
abstract class Traceback {
int i, j; // absolute coordinates
// Traceback2 objects for simple gap costs
class Traceback2 extends Traceback {
public Traceback2(int i, int j)
{ this.i = i; this.j = j; }
}And using the code above is the following allowed:
B[0] = new Traceback2(i-1, 0);
Any replies much appreciated. Thank you.

1)
public and private are access modifiers,
void and String return type declarations.
2)
It's called "inheritance", and "bad design" as well.
You should read the tutorials, you know?

How many ways Checks can be reprinted, apart from FBZ5 and "Void and reprint" Options

Hello All - Some times, when there is issue with Printer, Checks are not printed. In such a case, Users ask us how to print Checks.
Some options I know are that (1) Checks can be reprinted through T Code - FBZ5 and
(2) if Users are Ok with voiding Checks and use next available Check numbers, We use the option in the Variant - "Void and reprint" Option.
Some Users are not happy with this Solution as they do not want to waste Checks.
I am aware of only these 2 options. Can you please suggest me other alternatives we have to reprint Checks. Your valuable inputs are very helpful to us in this regard.
Thanks

Hi Hoysala,
Please use the the FBZ5 as per attached screenshot for reprint check.

Mass Check void and other AP items

Gurus,
1) The requirement is to have the ability to mark list of check as voided and then off set the payment document to an escheatment GL account instead of clearing account. They currently have a very huge number of checks they would escheat. I can't find any transactions that can meet mass void and post a clearing document on payment document to a different GL number.
Is there a way we can do without having a ABAP development?
2) When I creating an invoice in FB60, the payment term is defaulting from vendor master. But, the payment method is not defaulting from vendor master. The payment method field is left blank though my vendor master has payment method.
3) If I have multiple payment methods in vendor master and I have all payment methods in my proposal, which payment method the payment program considers in F110? the first payment method that is in vendor master?

HI Sri
So, it will consider the order of payment proposal and not the order in vendor master?
Yes you are correct
So I have a vendor with cw and my proposal order is entered as wc, will it consider w or c? first one in proposal or first one in vendor?
First one is in the proposal if that one is not available in vendor master ( nothing but payment document), then it will go to next payment payment.
if vendor has c and my invoice document is w and the proposal is w, will my proposal fails?
Payment programme will check the payment method at payment document level. So defiantly your proposal will execute.
Thanks
Sreenivas

Void and Reissue Payments

We have a scenario where a factor(associated with more than a hundred suppliers) has a payment returned from bank.
For the above scenario there could potentially be hundreds of checks involved if a factor's payment is returned as payables processs a seperate ACH for each supplier attached to the factor.
How can we customize or use the void and reissue program to enter a vendor number, factor number,factor site number or batch name, number(some sort of identifier) so as to prevent void and reissue each check.
This is of high priority, any help, suggestions are greatly appreciated.
Thanks in advance

Hi Vetri
following is how xml looks like:
<PositivePayDataExtract>
<OutboundPayment>
- <PaymentStatus>
<Code>VOID</Code>
<Meaning>VOID</Meaning>
</PaymentStatus>
- <PaymentAmount>
<Value>100</Value>
</OutboundPayment>
<OutboundPayment>
- <PaymentStatus>
<Code>ISSUED</Code>
<Meaning>Printed</Meaning>
</PaymentStatus>
- <PaymentAmount>
<Value>200.19</Value>
</OutboundPayment>
</PositivePayDataExtract>
When the detail records are @ level of <Outboundpayment> group. Here this will go for 2 times like for
example
accountno123 check no0001 100 ABC Corp
accountno234 check no0002 200 ABC Corp
Now when I write SUM @level of <PositivePayDataExtract> group..So it goes for only ONCE.
totaldetail_record_count=2 total_amount_300 ....[should be 200-100=100]
When I write your syntax like @<PositivePayDataExtract> group it just check ONLY ONCE and at the first record it cheks for condition
SUM((OutboundPayment/PaymentAmount[OutboundPayment/PaymentStatus/Code ='ISSUED']/Value))
SUM(OutboundPayment/PaymentAmount/Value
[OutboundPayment/PaymentStatus/Code=’VOID’])
BUT it DOES NOT go to 2nd record.
Bank wants SUM in one line..and still struggling..
Any thoughts?
thanks

Void and return help

whats the difference of using void and using the return?

The two are not in any way related, and there's no context in which you can choose between one and the other.
You're going to have to clarify your question.

Is there a way of passing a mixed cluster of numbers and booleans to teststand

Hi,
I have a labview VI that contains an output cluster containing both numeric and boolean results and would like to pass this to Teststand. At the moment I have coverted all my boolean results to '1/0' so that I can create a numeric array and can quite easily pass this to Teststand (using multiple numeric limit test).
Is there a way to pass mixed results to Teststand and write in the limits (example PASS and GT 5V) or do I have to stick with what I have?
Chris

Which test step type to use depends on what you have to analyze - a boolean condition? String? Number(s)? I can't tell you because I don't know what's in your cluster. If you click on the plus sign next to the parameter name "output cluster" you will see all paramters and their types, which are passed from the VI to TestStand.
You can either create a variable for the whole cluster, or you can assign all or just some values from within the cluster to variables.
The name of the variable (Locals.xxxxxxx... or FileGlobals.xxxxx...) ist what you type in the value field. You can also choose the variable from the expression browser by clicking on the f(x) button.
Are you new to TestStand, do you know how to work with variables in TS?
Maybe the attached picture gives you an example, there I am assigning the values from VI output "VoltageOutputArray" to the TS variable locals.VoltageMeasurement.
This variable ist used again on the tab "Data Source" as the Data Source Expression.

gedi
