What is the difference between "if else" and if?

Question

thank you...german answers are nice+

Answer 1

If you are German, say Lass uns Party machen!
Else if you are Chinese, say 入侵中国！
Else, say Hi, I hope you get it now.

Answer 2

Here is a french answer: with "if" you start to declare a condition "if" something... then if you want to give a 2nd condition you will add "else if" after the previous "if" with another condition. At the opposit of "else" alone, "else if" let you give a specific condition.
Usually your structure should looks like:

if()
{
}elseif()
{
}elseif()
{
}else
{
}
