7.)Var-args:
8) Annotations
17) what is the difference between Collection
and Collections?
A:
Collection is an
interface to represent a group of individual objects.
Collections is an
utility class for defining utility methods like sorting,searching and reversing
etc.
18) what is the
difference between ArrayList and vector?
A: ArrayList and
vector both are growable array or resizable array of objects.
But vector si
synchronized and ArrayList is not synchronized.
Vector is thread safe
and ArrayList is not thread safe.
ArrayList gives more
performance than Vector.
We can convert
ArrayList as a synchronized by using synchronized block or method.
If ArrayList reaches
its maximum capacity, it creates a new ArrayList object with new capacity as
(current capacity*3/2)+1.
If Vector reaches its
maximum capacity, a new Vector object will create with a capacity=current
capacity*2 i.e double.
19) what is
Enumeration?
A: Enumeration is an
interface to retrieve the objects one by one and contain two methods.
Boolean
hasMoreElements(); and Object nextElement();
We can get
Enumeration object only for legacy classes( vector,stack,Hashtable,properties,
Dictionay).
While iterating the
objects of enumeration, we can get only read-access.i.e while iterating we are
not allowed to perform any remove or modify operations.
20) what is Iterator?
A: Iterator is an
interface which can be applied for any Collection implemented classes(legacy
and non-legacy).
While iterating the
objects, we are allowed to perform remove operation aslo, in addition to read
operation.
This interace
contains the following methods.
Boolean hasNext();
Object next();
Void remove();
21) what is
ListIterator?
A: ListIterator is
the child interface of Iterator. This can be applied only for List implemented
classes(ArrayList, LinkedList, vector and stack).
This is a
bidirectional cursor. We can move either to forward or backward direction.
While iterating, we
are allowed to replace existing element with the new element, we are allowed to
add new elements and still we can perform remove operation aslo.
22) what is Marker
interface?
A: If an interface is
marked for some ability such type of interfaces are called marker interfaces.
Example: Clonable,
Serializable
If an interface with
out any method, obviously accept as marker interface. Even though interface
contains some methods, still we can consider as marker interface if it is
marked for some ability.
Example : Comparable
interface.
23) what is
Comparable interface?
A: This is present in java.lang package contains
the following one method.
public int compareTo(Object
obj)
-it returns –ve
integer if o1 has to place before o2.
-it returns +ve
integer if o1 has to place after o2.
It returns zero if o1
and o2 are equal.
All wrapper classes
and String class already implemented Comparable interface. But the String
Buffer doesn’t implement Comparable interface.
24) what is
Comparator?
A:
If you want to define
our own sorting we have to implement Comparator interface.
This interface
present in java.util package.
This interface
contain the following two methods.
Public int
compare(Object o1,Object o2)
-returns –ve value if o1 comes before o2.
- returns +ve value if o1 comes
after o2.
-returns zero if o1 and o2 are
equal.
Pubilc boolean
equals(Object obj)
25) what is the
difference between HashSet and TreeSet?
A: Elements are
inserted based on the hashcode hence insertion order is not preserved.
Duplicate object
insertion is not possible. If we are trying to add a duplicate object no chance
of getting RTE or CTE, add() just simply returns false.
Heterogenious objects
are allowed. Null insertion is possible but only once.
Hashset is best
choice for searching operations.
In TreeSet, duplicate
objects are not allowed. Insertion order is not preserved, but all the elements
are arranged in some sorting order. Heterogenious objects are not allowed
voilation leads to Runtime Exception saying ClassCastException.
26) what is the
difference between HashMap and Hashtable?
A: In HashMap, no
method is synchronized. HashMap object is not thread safe but performance is
high. As key and value, we are allowed to give null. This is non-legacy.
In Hashtable, methods
are synchronized. So it is thread safe. Performance is low. Null is not allowed
for both keys and values voilation leads to NPE. It is legacy.
Struts
1) what is struts?
-Struts is a web application framework.
-It is an open source software form Apache Software
Foundation(ASF).
2) what is the purpose of struts software? Or why
struts?
-Struts software is used develop java web applications that follows
MVC design pattern.
-If we use struts to develop industry strength web
applications (online applications), development is faster, easier, flexible ,
cost effective and easier to maintain.
3) How is Web application development easier, flexible
and faster if we use struts?
-If a web application is developed using struts
framework all the benefits of MVC available to the application.
-In an MVC based web application, controller
development is tougher and time consuming job. Moreover if the application
changes, we need to develop another controller again right from the scratch.
i.e reusability of controller is not possible.
-Struts provides a built-in controller which is
reusable for any kind of web application and provides major portion of
application logic required in any domain.
-Struts provides library support required to develop
our application specific application logic.
-struts provides library support to make view layer
development easier.
Note: Struts does not provide any support for building
the model layer. But it will allow us to use any thing as model. i.e a java
bean, an ejb , a spring bean or a web service.
MVC

Struts Architecture:
-In a struts(1.x) application the following architecture
elements involved.

2.form
beans(ActionForms)
3.Action
classes
4.configuration

5.jsp’s

ActionServlet:
-It is the centralized controller of any struts1.x
application.
-It acts as a single entry point access to any online
service of the web application(web site).
-It is a servlet class given by struts framework.
-In deployment descriptor of the struts application
(web.xml) we need to register the ActionServlet , pre-initialise it and create
its URL pattern so as to receive every client request.
-ActionServlet class uses struts configuration (struts-config.xml)
file to deal with flow control in the application.
Action class(es):
-For each specific functionality of the
application(use case) we generally developed one action class.
-Struts application is nothing but development of
action classes only.
-In action classes we develop our own application
specific application logic.
-Action classes are primarily responsible to transfer
data between view layer and model and vice versa.
-Action classes are the assistants for the ActionServlet.
-Action classes are the mini servlets.
-Struts application development means development of
Action classes only.
-we can’t write business logic in action class.
-struts 1.x , action classes are singleton . i.e. only
one instance is created and serves to all servlets.
ActionForms:
-An ActionForm is also known as a form bean in a
struts application. We need to develop* form beans of the application and
configure them in struts configuration file.
-ActionForm classes are pure java bean classes.
-Form beans acts as a data containers/channel for the
data that is transferring from view layer to model layer via controller layer.
It holds end user form data.
-Form beans are part of view layer.
Struts-config.xml
-This is the configuration file of the struts 1.x
application.
-During the initialization phase, ActionServlet loads
this file into memory and creates a set of configuration objects.
-struts-config.xml is used to create relationship
between view layer and controller. ActionSerlet uses this configuration file to
control the flow of the application.
JSPs:
-Jsps are developed to create input pages of the
struts application and response pages as well. Struts provides tag libraries
that simplify jsp development . Jsps will be synchronized with struts framework
nicely if we use struts tag libraries to develop the jsps.
4) ActionServlet is from which package and what are the
methods in it?
A: org.apache.struts.action.ActionServlet
ActionServlet methods:
getModuleConfig()
getRequestProcessor()
getResources()
addServletMappings()
destroy()
initServlet()
log()
initModuleConfig()
5) RequestProcessor is from which package and what are
the methods in it?
A: org.apache.struts.action.RequestProcessor
RequestProcessor methods:
processActionForm()
processPopulate()
processValidate()
processActionCreate()
ProcessLocate()
processSetContentType()
processSecurity()
