The following code works well with jvm.but it fails to answer when the same code is used a jsp bean
The following is bean file
package rand;
import java.util.Random;
public class rand {
int b;
Random r=new Random();

public rand(){
b=r.nextInt(7);
}
public int getrand(){
return b;
}
public static void main(String arg[]){
rand r=new rand();
System.out.println(r.getrand());
}
}
The following is jsp file
<%@ page import="java.util.Random" %>
<%
java.util.Random r=new java.util.Random(7);
int i=r.nextInt();
out.println(i);
%>
it gives the following error
Error during JSP page processing
java.lang.NoSuchMethodError: java.util.Random: method nextInt(I)I not found
Pls solve the above problem as quick as possible

An abstract class cannot be instantiated. Only its subclasses can be instantiated. You indicate that a class is abstract with the abstract keyword like this:
public abstract class Container extends Component {
Abstract classes may contain abstract methods. A method declared abstract is not actually implemented in the current class. It exists only to be overridden in subclasses. It has no body. For example,
public abstract float price();
Abstract methods may only be included in abstract classes. However, an abstract class is not required to have any abstract methods, though most of them do.
Each subclass of an abstract class must override the abstract methods of its superclasses or itself be declared abstract.
For more details, see section 8.1.2.1 of the Java Language Specification.
What's an interface?
An interface is an idea taken from Objective C. It describes the public methods that a class implements and their calling conventions without saying anything about how those methods are implemented. It is the responsibility of each class that implements an interface to provide code to handle the cases where the methods of the interface are called.
For example suppose you're writing an inventory database. The inventory may include many different items of many different types and classes. However each item in the warehouse needs to be able to tell you its price. Normally you would implement this by having each class extend a common superclass. However that's not always convenient. Instead you can declare an interface called Price with a price() method like this:
public interface Price {
public float price();
}
Any class which implements the Price interface must contain a method with the signature public float price(). The code of the price() method is included separately in each separate class which implements Price, not in the Price interface itself.
Different classes in your warehouse can each implement the Price interface like this:
public class Monopoly extends BoardGame implements Price {
// other methods
public float price() {
return 14.95;
}
}
When other code is passed an object, it can test whether the object implements Price with the instanceof operator. For example,
if (o instanceof Price) System.out.println("Subtotal is " + o.price());
In fact, interfaces can be used to tag objects. The java.rmi.Remote interface declares no methods. Its sole purpose is to indicate that an object is a remote object. In general, sub-interfaces of java.rmi.Remote will declare remote methods, however. For example,
public interface Hello extends java.rmi.Remote {
public String sayHello();
}
public class HelloImpl extends UnicastRemoteServer implements Hello {
public String sayHello() {
return "Hello";
}
}
