求大佬，关于抛出的NoSuchMethodException异常问题

问题描述：（用ecplise）这是book代码块和test代码块，构造方法和代码都正确，可是一直抛出NoSuchMethodException异常，

public class Book {

private int no;

private String name;

public double price;

public Book() {

super();

}

public Book(int no,double price, String name) {

super();

this.no = no;

this.name = name;

this.price = price;

}

public int getNo() {

return no;

}

public void setNo(int no) {

this.no = no;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public double getPrice() {

return price;

}

public void setPrice(float price) {

this.price = price;

}

@Override

public String toString() {

return "Book [no=" + no + ", name=" + name + ", price=" + price + "]";

}

}

public class BookTest {

public static void main(String[] args) {

try {

Class classBook=Class.forName("com.myimooc.test.Book");

Constructor constructor=classBook.getConstructor(new Class[] {

int.class,Double.class,String.class

});

Book book=(Book)constructor.newInstance(new Object[] {

001,75,"爱的教育"

});

System.out.println(book);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}
