Spped Up Your Internet

speed up your internet connection using firefox

1. Type “about:config” into the address bar and hit return. Scroll
down and look for the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time.
When you enable pipelining it will make several at once, which really
speeds up page loading.

2. Alter the entries as follows:

Set “network.http.pipelining” to “true”

Set “network.http.proxy.pipelining” to “true”

Set “network.http.pipelining.maxrequests” to some number like 30. This
means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer.
Name it “nglayout.initialpaint.delay” and set its value to “0?.
This value is the amount of time the browser waits before it acts on information it recieves.

If you’re using a brodband connection you’ll load pages 2-3 times faster now.

Android Tutorial with Examples

Custom Exception Development:

Custom Exception Development:

The new exception classes those are defined by developers are called user Defined Exception or custom exception.

These classes must be subclass of  either Throwable or any one of its subclass. It must be thrown based on condition failure.

According to the business requirements developers must write their own exception.

Its two steps process:

1. Define public class deriving from java.lang.Exception.
2. Define public no-arg and String parameter constructors with super() call.

For Example:

First Step:

NegativeNumberException.java

public class NegativeNumberException extends Exception

{

                public NegativeNumberException(){

                                super();

                }

                public NegativeNumberException(String msg){

                                super(msg);

                }

}

Using the above custome Exception in Our logic

Compute.java

public class Compute

{

                public int add(int n)throws NegativeNumberException

                {

                                if(n>0){

                                                return (n+10);

                                }

                                else

                                {

                                            throw new NegativeNumberException("Do Not Pass Number <=0");

                                }

                }

}

Example.java

class Example

{

                public static void main(String[] args)

                {

                                try{

                                                int n=Integer.parseInt(args[0]);

                                                Compute c=new Compute();

                                                int res=c.add(n);

                                                System.out.println("Result::"+res);

                                }

                                catch(ArrayIndexOutOfBoundsException aiobe){

                                System.out.println("Pleas pass ONE positive Integer number");

                                }

                                catch(NumberFormatException nfe){

                                System.out.println("Pleas pass only integer number");

                                }

                                catch(NegativeNumberException nne){

                                System.out.println(nne.getMessage());

                                }

                }

}
