var Variables in Java?!?!

Question

does it exist a Variable type that gives the variable automatically his type?
i mean in c# it is existing.
example;
var Var = 12

and then Var is a int

Answer 1

Nope, as far as i know all variables in java must be explicitly declared with a data type.

Answer 2

int var = 12;

/*this would give you a variable named "var" and a value of 12.java doesn't automatically declare variable type.
*/

Answer 3

It always pays to define your variables (even in c#) as if YOU don't know what type to set, how do you expect your program to know and capture errors? There's a saying: "Garbage In, Garbage Out" :)
