Discover the Ternary Operator
In computer programming, ?: is a ternary operator that is part of the syntax for a basic conditional expression in several programming languages. It is commonly referred to as the conditional operator, inline if (iif), or ternary if.
In Java this expression evaluates to:
If foo is selected, assign selected foo to bar. If not, assign baz to bar.
Object bar = foo.isSelected() ? foo : baz;
Java, in a manner similar to
C#, only evaluates the used expression and will not evaluate the unused expression.
