Create a package for the action class

3) LoginAction:

}
}

}

4)Registeraction.java

package com.action;


import javax.servlet.ServletRequest;

import com.opensymphony.xwork2.ActionSupport;


@SuppressWarnings("serial")
public class Registeraction extends ActionSupport {

}

private String Name,email,mobile,password;

public String getName() {

}
public String getEmail() {

public String execute() throws Exception
{
String status;
ConnectionDAO con = new ConnectionDAO();
int j=con.checkmail(email);

Commonly asked Top 26 Java Interview Questions

1.what is a transient variable? A transient variable is a variable that may not be serialized. If you don't want to serialize any objects then we have to use Transient Keyword. 2. Why do threads block on I/O? Threads block on i/o (that enters the waiting state) so that other threads may execute while the i/o Operation is performed. So your blocked thread of execution blocks only that: the thread of execution. 3. How are Observer and Observable used? Objects that subclass the Observable class maintain a list of observers. When an Observable object is updated it invokes the update() method of each of its observers to notify the observers that it has changed state. The Observer interface is implemented by objects that observe Observable objects(refer 1.4). 4. What is synchronization and why is it important?                      With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources.

All difference Question in java(common difference) (Collections)

1)Difference Between Interfaces And Abstract class? All the methods declared in the Interface are Abstract,where as abstract class must have atleast one abstract method and others may be concrete. In abstract class keyword abstract must be used for method, where as in Interface we need not use the keyword for methods. Abstract class must have Sub class, where as Interface can’t have sub classes.  An abstract class can extend only one class, where as an Interface can extend more than one. 2)Difference between Arrays and Vectors?             Because Vectors are dynamically-allocated, they offer a relatively memory-efficient way of handling lists whose size could change drastically. Arrays are fixed in size and it's wastage of memory problem. A Vector might be a good choice for such an arrangement. Moreover, Vectors have some useful member functions that make coding simpler. While in array is the bad choice of the arrangement and the code become more complex. Vecto
