我们可以使用泛型优化下面的代码吗

public class GenericExample<T> {
    private T data;

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

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public static void main(String[] args) {
        GenericExample<String> stringExample = new GenericExample<>("Hello");
        System.out.println(stringExample.getData());

        GenericExample<Integer> integerExample = new GenericExample<>(123);
        System.out.println(integerExample.getData());
    }
}
