Java:如何填充两个数组，在两个数组之间交替

public class ArrayFiller {
    public static void main(String[] args) {
        int[] array1 = new int[5];
        int[] array2 = new int[5];
        int[] result = fillArrays(array1, array2);
        System.out.println(Arrays.toString(result));
    }

    public static int[] fillArrays(int[] array1, int[] array2) {
        int[] result = new int[array1.length + array2.length];
        int index = 0;
        int i = 0;
        int j = 0;

        while (i < array1.length && j < array2.length) {
            result[index++] = array1[i++];
            result[index++] = array2[j++];
        }

        while (i < array1.length) {
            result[index++] = array1[i++];
        }

        while (j < array2.length) {
            result[index++] = array2[j++];
        }

        return result;
    }
}
