How does the ternary operator work?

Please demonstrate how the ternary operator works with a regular if/else block. Example:

Boolean isValueBig = value > 100 ? true : false;

Exact Duplicate: How do I use the ternary operator?

Boolean isValueBig = ( value > 100  ) ? true : false;


Boolean isValueBig;

if(  value > 100 ) { 
      isValueBig = true;
} else { 
     isValueBig = false;
}

The difference between the ternary operation and if/else is that the ternary expression is a statement that evaluates to a value, while if/else is not.

To use your example, changing from the use of a ternary expression to if/else you could use this statement:

Boolean isValueBig = null;
if(value > 100)
{ 
    isValueBig = true 
}
else
{
    isValueBig = false;
}

In this case, though, your statement is equivalent to this:

Boolean isValueBig = (value > 100);

When I was new to C++, I found that it helped to read this construct as follows:

Boolean isValueBig = if condition ? then x else: y;

(Notice that this isn't valid code. It's just what I trained myself to read in my head.)

Boolean isValueBig;

if (value > 100)
{
   isValueBig = true;
}
else 
{
   isValueBig = false;
}
