Question

Hy … I have the following code :

    try { Nrtrde record = new Nrtrde(); }
    catch (Exception e) {
        System.out.println(" ERROR\n");
        e.printStackTrace(); }
    finally { Nrtrde record = new Nrtrde(); System.out.println(" OK\n"); }

record.setSpecificationVersionNumber(specificationVersionNo);

and when compiling i get the following error :

NRTRDE\ENCODER.java:28: error: cannot find symbol
        record.setSpecificationVersionNumber(specificationVersionNo);
        ^
  symbol:   variable record
  location: class ENCODER
1 error

It seems I cannot create an object insinde a try {} and use it outside try {} ..

Why ?

Thank you

You have to declare it outside the block, but you can initialize it inside the block:

Nrtrde record = null;
try { 
    record = new Nrtrde();
} catch (SomeException e) {
    // handle exception here
}
if(record!=null){
    // do something with it
}

In Java, {} are block delimiters. Nothing is visible outside the block it is defined in. (Class members are an exception to this rule if the visibility allows it).
