How Does the Ternary Conditional Operator Work?

What is the Ternary Conditional Operator?

The ternary conditional operator, represented by a question mark "?" and a colon ":", provides a concise way to perform conditional evaluations.

Functionality

The ternary operator operates as follows:

boolean_statement ? true_expression : false_expression;

If the boolean statement evaluates to true, the true expression is executed, otherwise the false expression is executed.

Usage

The ternary operator can be utilized anywhere, not exclusively within print statements. It serves as an alternative to "if-else" statements and can simplify code by combining conditional evaluations and assignments into a single line.

Example

Consider the following code:

int row = 10;
int column;
while (row >= 1)
{
    column = 1;
    while(column <= 10)
    {
        System.out.print(row % 2 == 1 ? "<" : ">");
        ++column;
    }
    --row;
    System.out.println();
}

The ternary operator in this example is:

row % 2 == 1 ? "<" : ">"

If row is odd (i.e., row % 2 is equal to 1), the string "<>" is printed; otherwise, the string "> is printed.

Terminology and Resources

The ternary conditional operator is often referred to as "the ternary operator" or "the conditional operator." For further information on its usage, refer to the following resources:
