Ternary operator is a combination of if and else in a single statement.
Format
booleanExpression ? expression1 : expression2
Example
int outputVal = input > 10 ? input*2 : input*5;
In the above example, if input > 10, then output = input *2, else output = input *5
input = 12 => input > 10 => output = input *2 = 12 * 2 = 24
input = 5 => input < 10 => output = input *5 = 5 * 5 = 25
