The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
For example: If stock=0 Then message= order new stock Else message= there is stock End If. In the example code above, the part represented by (Boolean condition) constitutes a conditional expression, having intrinsic value (e.g., it may be substituted by either of the values True or False) but having no intrinsic meaning
condition: An expression which is evaluated as a boolean value. expression 1, expression 2: Expressions with values of any type. If the condition is evaluated to true, the expression 1 will be evaluated. If the condition is evaluated to false, the expression 2 will be evaluated.
The following presents examples for one of the most widely used object-oriented languages, Java, which should cover nearly every way that an object-oriented language can treat this problem. Unlike in C++, objects in Java are always accessed indirectly through references. Objects are never created implicitly but instead are always passed or ...
In certain computer programming languages, the Elvis operator, often written ?:, is a binary operator that returns the evaluated first operand if that operand evaluates to a value likened to logically true (according to a language-dependent convention, in other words, a truthy value), and otherwise returns the evaluated second operand (in which case the first operand evaluated to a value ...

The U.S. Postal Service, which has lost more than $100 billion since 2007, reported a net loss of $9.5 billion for its fiscal year ending Sept. 30, $3 billion more than last year, largely due to a ...
Java only enforces type information at compile-time. After the type information is verified at compile-time, the type information is discarded, and at run-time, the type information will not be available. [6] Examples of non-reifiable types include List<T> and List<String>, where T is a generic formal parameter. [6]
