Initialize a long in Java

Question

Primitive Data Types - oracle doc says the range of long in Java is -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. But when I do something like this in my eclipse

long i = 12345678910;

it shows me "The literal 12345678910 of type int is out of range" error.

There are 2 questions.

1) How do I initialize the long with the value 12345678910?

2) Are all numeric literals by default of type int?

Answer 1

1. You should add L: long i = 12345678910L;.
2. Yes.

BTW: it doesn't have to be an upper case L, but lower case is confused with 1 many times :).
