folks

I have the following:

if (mroApp.equals("WOTRACK"))
            {
                  
                  mroRepName = "woprint";
            }
but i want to add a statement into this:

if (mroApp.equals("WOTRACK"))
            and (mroSite.equals("JFK"))

   mroRepName = "woprint2";

so its an if esle

could anyone advise what the correct way

the pschuedo code is

if app =wotrack then repname=woprint else if app =wotrack and site=jfk then woprint2

all other will not have the site parameter bound

all help will do

The logic you specified is bad, because the second condition is a subset of the first.
If the second condition is true, the first condition is also true, and so fires first - you would never get into the second test.
Reversing the tests, putting the more specific one first would work.

I would probably write it like this.

  if ("WOTRACK".equals(mroApp)){
    mroRepName = "JFK".equals(mroSite) ? "woprint2" : "woprint";
  }

Using "WOTRACK".equals(mroApp) rather than mroApp.equals("WOTRACK") makes the code more robust by avoiding a null pointer exception if mroApp is null.
I also used a ternary statement to set the value of the mroRepName variable.
