In Java, you can use a ternary operator (also known as a conditional operator) to concisely specify a conditional expression. The ternary operator has the following syntax:
condition ? valueIfTrue : valueIfFalse
The ternary operator first evaluates the condition. If the condition is true, the operator returns the valueIfTrue. If the condition is false, the operator returns the valueIfFalse.
Here is an example of how to use the ternary operator to assign a value to a variable based on a condition:
int number = -10; int absNumber = number < 0 ? -number : number;
In this example, the conditionnumber < 0 is evaluated to true, so the absNumber variable is assigned the value of -number, which is 10.
You can also use the ternary operator as part of a larger expression. For example:
int number = -10; System.out.println(number < 0 ? "The number is negative." : "The number is positive or zero.");
In this example, the conditionnumber < 0 is evaluated to true, so the message "The number is negative." is printed to the console.
It is important to carefully consider the conditions and values in your ternary operator to ensure that your code is correct and easy to understand.
