How to set every item in the array A references to initialValue Java

public static void initialize(int A[], int initialValue) { ; }

this is the start of my code, asking how you can make it so that after running, every item in the array A becomes what I made initialValue. It's for a school assignment and the professor told us we can't use anything with an arrays function so no arrays.func

Thanks!

This can be an another solution,

/*
 * initialize a smaller piece of the array and use the System.arraycopy 
 * call to fill in the rest of the array in an expanding binary fashion
 */
public static void initialize(int A[], int initialValue) { 

    int len = A.length;

    if (len > 0){
        A[0] = initialValue;
    }

    for (int i = 1; i < len; i += i) {
       System.arraycopy(A, 0, A, i, ((len - i) < i) ? (len - i) : i);
    }

}

public static void main ( String [] args ) {
    int A[] = new int[5];
    initialize(A,1);
    for (int i : A) {
        System.out.println(A[i]);
    } 
}

OUTPUT: 1 1 1 1 1

You don't need that method.

Just call

Arrays.fill(A,initialValue);

BTW, your title has a mistake. Your array is a primitive array, so it won't contain references to initialValue, it will contain that int value multiple times.
