我得到了一种从String[]中移除空值的方法，我该如何为该函数创建一个方法并在以后调用它呢？Java

public class StringUtil {
    public static String[] removeEmptyStrings(String[] strings) {
        ArrayList<String> nonEmptyStrings = new ArrayList<>();
        for (String str : strings) {
            if (!str.isEmpty()) {
                nonEmptyStrings.add(str);
            }
        }
        return nonEmptyStrings.toArray(new String[0]);
    }
}

public class Main {
    public static void main(String[] args) {
        String[] strings = {"Hello", "", "World", "", "!"};
        String[] nonEmptyStrings = StringUtil.removeEmptyStrings(strings);
        for (String str : nonEmptyStrings) {
            System.out.println(str);
        }
    }
}

Hello
World
!
