<b>Description</h3></b>
<a name="67351"></a>
The <i>arrayref</i> must be of type <code>reference</code> and must refer to an array whose components are of type <code>char</code>. The <i>index</i> must be of type <code>int</code>. Both <i>arrayref</i> and <i>index</i> are popped from the operand stack. The <code>char</code> <i>value</i> in the component of the array at <i>index</i> is retrieved, zero-extended to an <code>int</code> <i>value</i>, and pushed onto the top of the operand stack.<p>
<a name="caload.Runtime"></a>
<b>Runtime Exceptions</h3></b>
<a name="67353"></a>
If <i>arrayref</i><em> </em>is <code>null</code>, <i>caload</i> throws a <code>NullPointerException</code>. <p>
<a name="67354"></a>
Otherwise, if <i>index</i> is not within the bounds of the array referenced by <i>arrayref</i>, the <i>caload</i> instruction throws an <code>ArrayIndexOutOfBoundsException</code>.<p>
