In Java, an if statement may be accompanied by an additional operator else, which is executed with a false logical expression.
If the logical expression is true, the if code block will be executed, otherwise the else code block will be executed.

if can have zero or one else, which should follow any if.
if can have zero for many else, and it must go to else.
after if ... else is successfully executed, nothing else of the remaining else if or else will be executed (checked).
