如何在java中为泛型类(及其子类)创建构造函数

public class GenericClass<T> {
    private T data;

    public GenericClass(T data) {
        this.data = data;
    }

    public T getData() {
        return data;
    }

    public static void main(String[] args) {
        GenericClass<String> genericString = new GenericClass<>("Hello");
        System.out.println(genericString.getData()); // 输出：Hello

        GenericClass<Integer> genericInteger = new GenericClass<>(123);
        System.out.println(genericInteger.getData()); // 输出：123
    }
}
