Half wrong, half right.  It would most likely still be considered most "used" worldwide.  Just not "spoken." 

Numbers are numbers man. Although english is the international language. 

You are wrong. More people speak english as a native and second language.

Well considering that a lot of people in China also "use" English (as well as many of the other heavily populated countries), the numbers really would be in favor of English.  No way to actually be able to count it, practically.  English is the official language of the most countries, though.  When you think about the top 10 most spoken languages, though, you start to realize how much fewer languages there are now than before.  Some languages are just dying off.  Russian and Japanese, I believe, make it to top 10. 

Java is the best language, followed by C++.

Brazilian Portuguese.

Because it was the 2012 Best language to learn.

By native speakers: Mandarin

By 2nd language skills: English

Think about how many native people of your country can speak Chinese, and how many chinese people can speak the language of your country.

I prefer C# but I love C/C++.

I voted english because it is the most useful currently. 

Correction, 2012 Best language to learn if you can already speak English.
