Boolean Logic: Uncovering the Power of Ternary Operators
The Problem: Checking Boolean Variables
Imagine you have three boolean variables: first, second, and third. Your task is to determine if at least two of these variables are true.
Ternary Operator to the Rescue
The ternary operator is a shorthand way of writing conditional statements. In our example, we can use it to simplify the code and make it more readable. Here’s how:
boolean first = true;
boolean second = false;
boolean third = true;
String result = (first && second) || (first && third) || (second && third)? "Two or more are true" : "Less than two are true";
System.out.println(result);
Output and Analysis
Running this code produces the following output:
Output 1: Two or more are true
Let’s break down what’s happening here. The ternary operator evaluates the conditional expressions inside the parentheses. If any of these expressions are true, the entire expression returns true, and the string “Two or more are true” is assigned to the result variable. Otherwise, it returns false, and the string “Less than two are true” is assigned.
Comparison with if…else Statement
While the if…else statement can achieve the same result, the ternary operator offers a more compact and expressive way to write conditional logic. By leveraging the ternary operator, you can simplify your code and make it more efficient.
