Melbourne - Dream place to visit

Melbourne is one of major cities in Australia and it very beautiful, greenery and specially for me it is more lovable place in the world. Even I couldn't get chance to visit Melbourne till today, I have observed many places in the web sites and TV channels and I loved it.

If I could get the chance to visit, the fist place I like to visit is the Cricket Ground. It is one of the biggest stadiums in the world with 100,000 seating capacity. Apart from the Cricket, it is very famous for the Foot ball. It's my dream place to visit since I habituated with watching and playing cricket.

The next place I would like to visit is the historical market i.e. QUEEN VICTORIA MARKET. I would like to taste the all the verities of Australian sea food items, vegetable food items and different fruits available in Australia and complete the shopping on lovable items.

One of my most lovable thing which I can't say by my mouth but just understand from below. Like to have one pe......g in Melbourne.

From childhood days I am hearing about 'Penguin', reading in books and watching in movies. So, I would like see the Penguins in Penguin Island and enjoy the moments.


You may have different taste than me or my like other things when compared to my interests. If you want to know more about Melbourne just visit : www.visitmelbourne.com/in.


Once you know more about Mebourne, I am sure you definately like to visit Melbourne and it will become a dream place to you. Finally I would like to say, "Melbourne is a city that knows how to live".

So...

…it's your time to visit Melbourne NOW!!!

Get Answers for mathematical equations from Google Search

Every one know that Google is always coming up with the new inventions and trying to make the Google as life to the user in future. Below is one of the new invention from the Google.


Google has just released a new 34-button scientific calculator in the Google serch options. Go ahead and enter an equation into Google Search. Try 2+2. Now, instead of simply coming up with the answer, Google presents you with a full, 34-button scientific calculator. You can also find the answers for Trigonometric functions and 'Pi' functions


You can also access the calculator with Desktop Voice Search. Just click the little microphone icon in the search bar, speak your equation out loud and wait a split second for your answer. A pared-down version of the calculator also appears during mobile searches.

Today I have tested the calculator with the mathematical equations, triganometric functions and others..., it is amazing for me.

So, why to wait? start searching mathematical equations or mathematical functions in google.... Hope you will enjoy

Are you waiting for Windows 8 to use?

If you are eagerly waiting for new versions of windows with more features, this is the time to know about the windows 8. Every one knows that Microsoft gave a wonderful OS with Windows 7, but still people want more comfort level in using the Computers than earlier.

Convert charr array to String in Java

1. We can convert char array to String by passing the array to String constructor.

public void convertCharArrayToStringOption1() {

    char[] charArray = new char[] { 'a', 'b', 'c', 'd' };

    System.out.println("The new String Array is : "+new String(charArray));

}

2. We can also pass the char array to 'valueOf()' static method of String class:

public void convertCharArrayToStringOption1() {

    char[] charArray = new char[] { 'a', 'b', 'c', 'd' };

    System.out.println("The new String Array is : "+
String.valueOf(charArray));

}

Marker or Tag interface in java

An interface is called a marker interface when it is provided as a handle by java interpreter to mark a class so that it can provide special behaviour to it at runtime and they do not have any method declarations.

Java Marker Interface Examples

• java.lang.Cloneable
• java.io.Serializable
• java.util.EventListener
• 
  

Why we need Marker Interface?

Suppose you want to persist (save) the state of an object then you have to implement the Serializable interface otherwise the compiler will throw an error. To make more clearly understand the concept of marker interface you should go through one more example.

Suppose the interface Clonable is neither implemented by a class named Myclass nor it’s any super class, then a call to the method clone() on Myclass’s object will give an error. This means, to add this functionality one should implement the Clonable interface. While the Clonable is an empty interface but it provides an important functionality.

We cannot create marker interfaces, as you cannot instruct JVM to add special behavior to all classes implementing (directly) that special interface.

From java 1.5, the need for marker interface is eliminated by the introduction of the java annotation feature. So, it is wise to use java annotations than the marker interface. It has more feature and advantages than the java marker interface.
