In Java, it is possible to use the ternary operator (also known as the conditional operator) to write an if-else statement in a single line of code. The ternary operator is a shorthand way to write an if-else statement that returns a value based on a condition.
The syntax for the ternary operator is as follows:
condition ? valueIfTrue : valueIfFalse
Here is an example of how to use the ternary operator to write an if-else statement in a single line of code:
int result = (x > y) ? x : y;
In this example, the ternary operator is used to assign the value of x to the result variable if x is greater than y, and the value of y to the result variable if x is not greater than y.
You can also use the ternary operator to execute different blocks of code based on a condition, by using a method call or a block of code as the valueIfTrue or valueIfFalse.
Here is an example of how to use the ternary operator to execute different blocks of code based on a condition:
(x > y) ? doSomething() : doSomethingElse();
In this example, the method doSomething() is called if x is greater than y, and the method doSomethingElse() is called if x is not greater than y.
Note that the ternary operator is often used as a shorthand way to write an if-else statement, but it is not always the most readable or maintainable option. It is generally a good idea to use the full if-else syntax if your code is more complex or if the condition and actions are not easy to understand in a single line of code.
