Convert Kotlin Array to Java varargs

Question

How can I convert my Kotlin Array to a varargs Java String[]?

val angularRoutings = 
    arrayOf(\"/language\", \"/ho         


        

Answer 1

There’s the spread operator which is denoted by *.
The spread operator is placed in front of the array argument:

antMatchers(*angularRoutings)

For further information, see the documentation:

When we call a vararg-function, we can pass arguments one-by-one, e.g. asList(1, 2, 3), or, if we already have an array and want to pass its contents to the function, we use the spread operator (prefix the array with *):

Please note that the spread operator is only defined for arrays, and cannot be used on a list directly. When dealing with a list, use e.g.toTypedArray() to transform it to an array:

 *list.toTypedArray()
