<p><strong>Case 1</strong> <code>"hello" "world"</code> (NO ERROR)</p>

<p><strong>Case 2</strong> <code>"hello"+"world"</code> (ERROR)</p>

<p>I know that the <code>+</code> operator must atleat have one of its operand as <code>string type</code>,not <code>string literal</code>.</p>

<p>Thing is,both of the cases doesnt make sense,since we can include it into a <code>single literal</code> !</p>

<p>Why is Case 1 allowed then!</p>
