Explain Ternary operator with an example.

condition ? expression 1 : expression 2

Ternary operator evaluates the condition. If the condition is true then result of ternary operator is the value of expression 1. Otherwise the result is the value of expression 2.

Example:

boolean isLeapYear = true;  
int febDays = isLeapYear ? 29 : 28;

Here, the ternary operator checks if the value of boolean variable isLeapYear is true or false. As it is true, expression 1, which in this example is the value 29, is the result of the ternary operator. So, int variable febDays becomes 29.
