Whats a "var"

Answer 1

There is no var in Java. If you didn't mean litteraly "var" and just meant variable, then by definition it is just something that stores a value. Like an int or String.

int x;
^^ In general terms this is a variable of type int. But there is no var keyword in Java.

If you meant Javascript, the keyword 'var' is short for 'variable', which declares (creates) a variable.
A variable can later be used to retrieve whatever the variable is storing.

var x = 15;

alert(x);

Output: 15.
This should be covered in the Javascript course.
