怎么打才能在控制台输出这些书本信息？

可以在Book类中实现一下toString()方法，然后再main函数中System.out.println(b3)，或者直接在main函数中打印：
System.out.println(b3.getName()+"," +b3.getBookcard()+"," +b3.getEd() + ","+b3.getPress() + "," +b3.getTime() + "," + b3.getPage() + "," + b3.getPrice() );

1.如果book类已经重写tostring()方法 直接在最后输出：

System.out.println(b3);

2.一个属性一个属性输出 进行拼接 前提book类中对每个属性有get方法：

System.out.println(b3.getName() + "\t" + b3.getBookcard() + "\t" + b3.getEd() + "\t" + b3.getPress() + "\t" + b3.getTime() + "\t" + b3.getPage() + "\t" + b3.getPrice());
