public class shiyan<T>{

private T[] bookInfo;

public shiyan(T[] bookInfo) {

this.bookInfo=bookInfo;

}

public void showBookInfo() {

System.out.println("书名\t作者\t价格\t是否附赠光盘");

System.out.println("--------------------------------------------");

for (int i = 0; i < bookInfo.length; i++) {

System.out.println(bookInfo[i]+"\t");

}

}

public static void main(String[] args) {

String[] info={"《零基础学java》","明日科技","价格","是否附赠光盘"};

shiyan<String> book=new shiyan<String>(info);

book.showBookInfo();

}

    }

问题：这一段代码中为什么bookInfo[i]会等于info[i]
