如何在Java中将字符串数组转换为字符数组？

public class StringArrayToCharArray {
    public static void main(String[] args) {
        String[] stringArray = {"Hello", "World"};
        char[] charArray = new char[stringArray.length];

        for (int i = 0; i < stringArray.length; i++) {
            charArray[i] = stringArray[i].toCharArray()[0];
        }

        System.out.println("String Array: " + Arrays.toString(stringArray));
        System.out.println("Character Array: " + Arrays.toString(charArray));
    }
}
