POUsing Integer in Switch Statement
text
Body
copied!<p>For various business reasons I want to hold some static IDs in one of my classes. They were originally <code>int</code> but I wanted to change them to <code>Integer</code> so I could do an equals on them (ie <code>MY_ID.equals(..)</code> which avoids NPEs)</p> <p>When I change them to Integer I get errors in my switch statement. The <a href="http://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html" rel="noreferrer">docs</a> say that Integer should be ok within Switches. </p> <p>To quote </p> <blockquote> <p>[Switch] also works with enumerated types (discussed in Enum Types), the String class, and a few special classes that wrap certain primitive types: Character, Byte, Short, and Integer (discussed in Numbers and Strings).</p> </blockquote> <p>In my code below if i is a <code>int</code> then it compiles. When it is an <code>Integer</code> it doesnt saying that a <code>constant expression is required</code>. I have tried doing <code>.intValue()</code> but this doesnt work either.</p> <p>Am I being really stupid? Or completely misreading the <a href="http://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html" rel="noreferrer">docs</a>?</p> <pre><code>private static final Integer i = 1; @Test public void test() { switch(mObj.getId()){ case i: //do something default: //do something default } } </code></pre> <p>Thanks for any pointers here. For the time being I am keeping them as <code>int</code> and doing <code>new Integer(myint).equals(...)</code></p>
