Boolean literals can be either `true` or `false`. In C (and some other languages) it is common to use numbers to

represent true or false, but this will not work in Java. For example,

{% highlight java %}

boolean t = true; // Legal

boolean f = 0; // Compiler error!

int x = 1; if (x) { } // Compiler error!

{% endhighlight %}

A char literal is represented by a single character in __single quotes__:

{% highlight java %}

char a = 'a';

char b = '@';

{% endhighlight %}

You can also assign unicode value to a `char` variable, like:

{% highlight java %}

char letterN = '\u004E'; // The letter 'N'

{% endhighlight %}

Note, characters are nothing but __16-bit unsigned integers__. So, you can assign a number literal, assuming it will fit

into the unsigned 16-bit range (0 to 65535) to a `char` variable. For example, the following are all __legal__:

{% highlight java %}

char a = 0x892; // hexadecimal literal

char b = 982; // int literal

char c = (char)70000; // The cast is required; 70000 is

// out of char range

char d = (char) -98; // Ridiculous, but legal

{% endhighlight %}

And the following are __not legal__ and produce compiler errors:

{% highlight java %}

char e = -29; // Possible loss of precision; needs a cast

char f = 70000; // Possible loss of precision; needs a cast

{% endhighlight %}
