Answer / sujeev
IOC(Inversion of control)is a technique that allows object
configuration to be moved out of code and into a
configuration file. With Spring IOC, this is typically done
with an XML file.
The steps to use Spring IOC are:
1. Write Java Bean classes, with getter and setter methods
for each property to be configured by Spring.
2. Create an XML file that describes the Java Beans to be
configured.
3. Use an XMLBeanFactory to create configured beans. There
are other ways to read bean descriptions, but using an
XmlBeanFactory is more common.

Answer / shoban
Ioc is the core container for complete spring framework.
Ioc is designed to just perform "dependency injection".
Spring core module comes with basic spring container whose
name will be "BeanFactory"
Ioc can be designed based on Servicelocator designpattern.
Spring basically supports 2 kinds of injection
1.setter injection
2.constructor injection.
Based on the injection you choose and write proper java code
in bean class.
Dependency injection uses the hollywood principal "Don't
call me i will call u".

Answer / krishna chandra mohan a
IoC or Inversion of Control is a design pattern that
provided instances of a bean or class to another when they
needed. That means, we do not have to use new keyword to
create instance of dependent class. We will just create a
reference of dependent class and IoC pattern will set the
instance to the reference when needed.

Answer / madhusudhakar
when we develop a project we will be providing code to take
care of creating the objects and setting dependencies of the
objects(this is normal course).
if we use spring container we need not creating the code for
creating the objects and setting up the dependencies. the
spring container takes care of this task . the task that is
normally carried out by our code is getting carried out by
the spring container this is called as IOC

Answer / sagar date
The org.springframework.beans.factory.BeanFactory is the
actual representation of the Spring IoC
container that is responsible for containing and otherwise
managing the aforementioned beans.
The BeanFactory interface is the central IoC
container interface in Spring. Its responsibilities include
instantiating or sourcing application objects, configuring
such objects, and assembling the dependencies
between these objects.

Answer / alok kumar ranjan
IoC or Inversion of Control is one of the core features of
Spring. It helps in simplifying the implementation of
business logic. To use the Spring Framework to its full
potential, understanding the IoC container of the framework
is essential.
