Short form for Java if statement

Question

I know there is a way for writing a Java if statement in short form.

if (city.getName() != null) {
    name = city.getName();
} else {
    name=         


        

Answer 1

1. You can remove brackets and line breaks.

if (city.getName() != null) name = city.getName(); else name = "N/A";

---

2. You can use ?: operators in java.

Syntax:

Variable = Condition ? BlockTrue : BlockElse;

So in your code you can do like this:

name = city.getName() == null ? "N/A" : city.getName();

---

3. Assign condition result for Boolean

boolean hasName = city.getName() != null;

EXTRA: for curious

In some languages based in JAVA like Groovy, you can use this syntax:

name = city.getName() ?: "N/A";

The operator ?: assign the value returned from the variable which we are asking for. In this case, the value of city.getName() if it's not null.
