对象数组

对象数组案例如下：是动态实例化数组

class Book{
 private String title;
 private double price;
 public Book(String t,double p){
  title=t;
  price=p;
 }
 public String getInfo(){
 return "jiag:"+title+"shum"+price;
 }
 }

public class StringDemo{
    public static void main(String args[]){
   Book books[]=new Book[3];
   books[0]=new Book("java",151);
 books[1]=new Book("jav",11);
 books[2]=new Book("jaa",121);
  for(int i=0;i<books.length;i++){
  System.out.println(books[i].getInfo());  
  }
  }
}
