Kotlin asterisk operator before variable name or Spread Operator in Kotlin

Question

I want to know what exactly an asterisk does before a variable name in Kotlin. I saw this (*args) in a Spring boot Kotlin example:

@SpringBootApp

In Java you can pass an array as is but an advantage of unpacking an array with spread operator * is that spread operator lets you combine the values from an array and some fixed values in a single call. Java doesn't support this.
