Java get set one liner

Question

I'd like to do a get and set if null like so.

Foo foo = new Foo();
...
String test = foo.getTest() == null ? foo.setTest("this") : foo.getTest();

The thing is set is a void method. What the right way to set this String test to ?

Answer 1

Don't use a one liner.

String test = foo.getTest();
if (test == null) {
    test = "this";
    foo.setTest(test);
}
