Java concenate with an offset ?

[Former Member]

Hi,

For Javamen...

I'm facing to a stupid pb: easy in abap, but in Java is another story...

Here's what I want to do in Java (with a UdF):

Source = abcdefgh.

Target = 1234567

Target+10(6) = Source(6).

Thus result should be: Target = "1234567___abcdef" with three spaces "_" (for this example), coz the first part is on 10 characters.

My pb is not to get the 6 char of Source (cf. fct substring), but it's the managment of the offset "+10".

Hi,

source and target are two input values -> is this right?

Hi Patrick

Yes for instance, but I think the pb is not here coz we will have two inbound parameters of our UdF.

Hi,

if I understand you right you want to bring the target value to a length of 10.

In this case you could write a udf with one parameter (here a) like this:

if (a.length() < 10) {

while (a.length() < 10) {

a = a + " ";

}

}

return a;

Then you can use the standard concat-function with the output of the udf and the source value.

(Works only if your target could not be longer than 10 otherwise you have to check this also)

Yes, I thank also to that, but is there a standard Java function for this offset ?

it takes 1 line in abap... and a couple in Java.

Hi,

Can you pls. tell me how can you do this in a single line in ABAP?

Thanks

There is no offset function in JAVA

sour>myudf->Target

This is your udf

function myudf(String a,Container container)

{

if (a.length()<10)

{

for (int i=a.length();i<10;i++)

a+="_";

}

return a;

}

Then do it in an ABAP Mapping.

PS: lines of code means nothing, unless you're talking about assembly.

P.S: Hopefully developper cannot use what they want to do a mapping... Else maintenance will be not really happy / easy....

Hi Amit,

yes I can, it's written if my first post...

Target+10(6) = Source(6).
