Hi, When developing some logic to see if something exists and if it doesn't, then create it, he thinks the following solution is the preferred one:

Code:

OurObject obj;
// create a reference to the object if it exists, if it doesn't exist, the method just returns null
obj = someotherobject.somemethodwhichreturnsthe-existingobject(argument)
try {
  // next call will throw exception if object was not found in before call
  obj.somemethod();
} catch (Exception e) {
  // apparently the object did not exist, so let's create it
  obj = someobject.createobject(arguments);
}

i think its more correct to do it this way:

Code:

OurObject obj;
// create a reference to the object if it exists, if it doesn't exist, the method just returns null
obj = someotherobject.somemethodwhichreturnsthe-existingobject(argument)
if (object == null) {
  // apparently the object did not exist, so let's create it
  obj = someobject.createobject(arguments);
}

what do you think is better, faster, whatever.
Thanks
