The ?: operator is a ternary operator that evaluates exactly one of the expression operands.

Operator Description

The ternary ?: operator takes the following form:

Logical ? Expression : Expression

If the left operand is true, then the middle operand is evaluated. If the left operand is false, then the right operand is evaluated. Note that there is no scenario in which both the middle and right operands are evaluated, because their evaluation is mutually exclusive. The value of this expression is the value of the evaluated expression.
