Line 98:

In Java 5.0 enums are lower case, like types, and have their own syntax.

<syntaxhighlight lang="java">

<code>

private enum Coin {

penny(1), nickel(5), dime(10), quarter(25);

Line 105:

public int value() { return value; }

}

</syntaxhighlight>

</code>

Also enums can be used in switches. Classes cannot be used this way.

<syntaxhighlight lang="java">

<code>

switch(menu) {

case FILE:

Line 124:

break;

}

</syntaxhighlight>

</code>

Check out

Line 133:

In Java even arrays are technically classes ie

<syntaxhighlight lang="java">

<code>

Object o = new int[10];

</syntaxhighlight>

</code>

same in c# --[[User:Motherofinvention|Motherofinvention]] 01:05, 29 June 2006 (UTC)

Further compiling:

<syntaxhighlight lang="C#">

<code>

public class Test {

private int enum = 10;

}

</syntaxhighlight>

</code>

Yields the error:

<code>

Test.java:2: as of release 1.5, 'enum' is a keyword, and may not be used as an identifier

(try -source 1.4 or lower to use 'enum' as an identifier)

Line 153 ⟶ 152:

^

1 error

</code>

My inclination is to call it a keyword, because of the new syntax, and the compiler error.

: Yeah, it seems pretty clear that <code>enum</ttcode> is a keyword in Java. [[User:Neilc|Neilc]] 01:08, 10 Mar 2005 (UTC)

Keyword or not, <code>enum</code> is a feature of all (or nearly all?) programming languages in the C language family, and as such is uninteresting in this context. I've deleted the reference, hope that's OK... [[User:GregorB|GregorB]] 12:37, Apr 29, 2005 (UTC)

Line 630 ⟶ 628:

The following text, specifically the highlighted section, is inaccurate. Java does not support variadic functions in any release.

<blockquote>"With the Java 5.0 release, this trend may have been broken, as it introduced several new major language features: foreach statement, autoboxing, <fontspan colorstyle="color:red;">methods with variable number of parameters (variadic functions)</fontspan>, enumerated types, generic types, and annotations. It should be noted that all of those, except generic types, were already present in C# by that time, some under different names.[13]"</blockquote>
