Meaning of if( item1 ? item2) : item3

Question

I was looking through a java book and i remember reading something about using the ? operator for if statements an I cannot find the reading material anymore. I tried googling the topic but it yielded nothing. So how does the below piece of code

if( itemA ? itemB) : itemC

work

I think you mean either `if( itemA ? itemB : itemC)` or just `itemA ? itemB : itemC`. It's called a ternary/conditional operator/expression. — Carcigenicate, Oct 29 '18 at 12:43
You're missing the right name when you search - 'ternary operator' or 'ternary conditional operator', e.g. https://alvinalexander.com/java/edu/pj/pj010018 — Pete Kirkham, Oct 29 '18 at 12:44

The "?" ":" correspondans to the ternary operator

I.e : a ? b : c means "if a is true, return b, else return c"

Its called ternary operator. Syntax will be like

(Condition) ? (Value to be assigned if the condition is true) : (Value to be assigned if the condition is false)

Look at the examples given below for understanding the usage

Eg.

public String getGender(String genderCode){

   return gender.equals("M")?"Male":"Female";

}
