copied!<p>The signature</p> <pre><code>static private <E extends Enum<E>> getEnum(String enumFullName) </code></pre> <p>isn't doing you any good here.</p> <p>The <code><E extends Enum<E>></code> allows the caller of the method to assign the result of <code>getEnum</code> to any <code>enum</code> type they want without any casting:</p> <pre><code>SomeEnum e = getEnum("com.foo.SomeOtherEnum.SOMETHING"); // ClassCastException! </code></pre> <p>However, that doesn't make any sense... if the caller knew what specific type of <code>enum</code> the method would return, they could do something more sensible like <code>SomeEnum.valueOf("SOMETHING")</code>.</p> <p>The only thing that makes sense here is for <code>getEnum</code> to just return <code>Enum<?></code>, which seems like what you really want to do anyway:</p> <pre><code>static private Enum<?> getEnum(String enumFullName) { String[] x = enumFullName.split("\\.(?=[^\\.]+$)"); if(x.length == 2) { String enumClassName = x[0]; String enumName = x[1]; try { @SuppressWarnings("unchecked") Class<Enum> cl = (Class<Enum>) Class.forName(enumClassName); return Enum.valueOf(cl, enumName); } catch(ClassNotFoundException e) { e.printStackTrace(); } } return null; } </code></pre> <p>The above compiles with no warnings and works properly. The cast to <code>Class<Enum></code> warning is suppressed because we know that it isn't safe to do that and that <code>Enum.valueOf</code> will blow up if the class with the given name isn't an <code>enum</code> class and that's what we want to do.</p>
