int six = 06; // equal to decimal 6

int seven = 07; // equal to decimal 7

int eight = 010; // equal to decimal 8

int nine = 011; // equal to decimal 9

system you use, the range of values that an `int` can hold is always between $$ -2^{31} $$ to $$ +2^{31}-1 $$.

Hexadecimal (hex for short) numbers are constructed using 16 distinct symbols. They have a radix of 16. Counting from

0 through 15 in hex looks like this:

{% highlight java %}

0 1 2 3 4 5 6 7 8 9 a b c d e f

{% endhighlight %}

Java accepts uppercase or lowercase letters for the extra digits _(one of the few places Java is not case-sensitive)_.

You represent an integer in hexadecimal form by placing a `0x` in front of the number, as follows:

{% highlight java %}

int x = 0X0001; // equals to decimal 1

int y = 0x7fffffff; // equals to decimal 2147483647

int z = 0xDeadCafe; // equals to decimal -559035650

{% endhighlight %}

All four integer literals (binary, octal, decimal, and hexadecimal) are defined as `int` by default, but they may also

be specified as `long` by placing a suffix of `L` or `l` after the number:

{% highlight java %}

long jo = 110599L;

long so = 0xFFFFl; // Note the lowercase 'l'
