A ternary operator allows you to assign one value to the variable if the condition is true, and another value if the condition is false. The if else block example from above could now be written as shown in the example below. var num = 4, msg = “”; msg = (num === 4) ?
What is ternary operator?

What is the use of syntax and ternary operator?
The ternary operator is used to execute code based on the result of a binary condition. It takes in a binary condition as input, which makes it similar to an ‘if-else’ control flow block. It also, however, returns a value, behaving similar to a function.
Which operators are known as ternary operators?

- Using when when (a) { true -> print(“value b”) false -> print(“value c”) else -> { print(“default return in any other case”) } }
- Null Safety val a = b ?: c.
What is binary operator in Java?
