Class Outer{int a;Outer (){a=10;}public static void main(String args[]){final Outer o1=new Outer();Outer o2=new Outer();class inner{inner(){o1.a=20;//allowed//o2.a=30; not allowed}}}}Why inner classes can access only final variables as illustrated? Thanks in advance!

Inner classes can also access method parameters that are declared to be final.

Logical grouping of classes—If a class is useful to only one other class, then it is logical to embed it in that class and keep the two together. Nesting such "helper classes" makes their package more streamlined.
Increased encapsulation—Consider two top-level classes, A and B, where B needs access to members of A that would otherwise be declared private. By hiding class B within class A, A's members can be declared private and B can access them. In addition, B itself can be hidden from the outside world.
More readable, maintainable code—Nesting small classes within top-level classes places the code closer to where it is used.

Defining a class within another class is known as nested class.If class B is defined within class A, then B is known to A, but not outside of A.Class B has access to the members, including private members of the Class A.However,the class A does not have access to the members of Class B.

Floating Point Numbers

It is obviously give 0.2 answer ...
Code- #include <iostream>

Sandhya.Kishan
- Mar 12th, 2012
The floating-point arithmetic in most computer languages is based on binary fractions (1/2, 1/4, 1/8, 1/16, ...) and not decimal fractions (1/10, 1/100, 1/1000, 1/1000,...)there is no ActionScript Number that is exactly equal to 0.1 because it require an infinite number of binary fractional bits.

Visual Studio uses partial classes to separate auto-generated code from user-generated code. Example:Let us consider that visual studio creates a file called Form1.Designer.cs which holds the designer-related, auto-generated code. So in both Form1.cs and Form1.Designer.cs the Form1 class is declared as partial and the compiler joins them into one.

When different programmers work on single project and all write a code in class .Every programmer declare this class as Partial class and implement own code at the end of the day this partial class have all functionality that all programmers put in this class.
