Line 1,421: This approach also works well with [[wp:Bayes'_theorem\|Bayes' theorem]], as false matches 0% probability and true matches 100% probability. =={{header\|Java}}== <p> Java has <tt>true</tt> and <tt>false</tt> keywords, representing the only values of type <tt>boolean</tt>. There are also object wrappers <tt>Boolean.TRUE</tt> and <tt>Boolean.FALSE</tt>, of type <tt>Boolean</tt> which may be un-boxed into <tt>boolean</tt>s (auto-unboxed in Java 1.5+). There are no automatic conversions from any other types into <tt>boolean</tt>, and it is a compile-time error to use any type other than <tt>boolean</tt> or <tt>Boolean</tt> in a place that expects a <tt>boolean</tt> (e.g. if-statement condition, while-statement condition, operand of a logical operator, etc.). In Java, <code>true</code> and <code>false</code> are used to reference a <code>boolean</code> value.<br /> There is no use of <kbd>0</kbd> and <kbd>1</kbd>, or <kbd>undefined</kbd> vs. <kbd>defined</kbd>. </p> <p> As with the other primitive data-types, <code>boolean</code> has a wrapper class, <code>Boolean</code>, which includes a set of valuable <kbd>boolean</kbd> operations. </p> <syntaxhighlight lang="java"> boolean valueA = true; boolean valueB = false; </syntaxhighlight> <p> Or. </p> <syntaxhighlight lang="java"> Boolean valueA = Boolean.TRUE; Boolean valueB = Boolean.FALSE; </syntaxhighlight> <p> Additionally. </p> <syntaxhighlight lang="java"> Boolean valueA = Boolean.valueOf(true); Boolean valueB = Boolean.valueOf(false); </syntaxhighlight> =={{header\|JavaScript}}== The Boolean type has two values: <code>true</code> and <code>false</code>
