Do an internet search for the term "java varargs" for java specific info, or "programming ellipsis" for a more general description. Lots of info, for instance, the following link:
Varargs

[mk12345]

That feature is called varargs, and it's a feature introduced in Java 5. It means that function can receive multiple String arguments:
The parameter that gets the ... must be the last in the method signature.
public void myMethod(String... strings){
for(String whatever : strings)
{

}

The spread operator allows you to expand an expression in places where you would expect multiple arguments (in functions) or multiple elements (in arrays).

let someArguments = ['hi','bye'];

function logArgs (arg1, arg2) {
return console.log(`${arg1} ${arg2}`);
}

logArgs(...someArguments); //hi bye
