Java curly braces in this specific scenario

Question

What do the curly braces with the number 42 do to the array in this scenario?

Class Example {
    static void g(int[] array) {
        array[1] = 19;
        array = new int[] {42};
    }

    static void f() {
        int [] array = new int[1];
        g(array);
    }
}

Answer 1

array = new int[] {42};

This line creates a new integer array with size 1, whose only element is 42, and assigns it to array. It is equivalent to

array = new int[1];
array[0] = 42;

Answer 2

this is actually creating array with size of 1 and only element that is array[0]=42
