I suspect Java decides you want to see the result in decimal.

EDIT:

If you're unsure what octal, decimal and hexadecimal means, check out:

Any numeric literal that starts with a "0" is considered to be written in Octal - or base 8. That means you can only use the digits from 0-7, and each position represents powers of 8.

Literals that begin with "0x" are considered Hexadecimal, which means you can use the digits 0-9 plus A-F. Each position represents a power of 16.

This sounds weird, but makes perfect sense for computers and representing things stored in computers.

Did you expect something else? For example, did you expect that it would display "0x10" when you initialize the integer with 0x10?

Note that decimal, octal and hexadecimal are just different ways to represent numbers. But the number itself it just a number and nothing more: it does not have some property that says that the number is decimal, octal or hexadecimal. In other words, the variable doesn't know anything about how you wrote it in your source code.
