<h1>new-array</h1>
<h2>Purpose</h2>
<p>
Construct a new array of the indicated type and size. The type must be an array
type.
</p>
<h2>Details</h2>
<table class="instruc">
<thead>
<tr>
<th>Op & Format</th>
<th>Mnemonic / Syntax</th>
<th>Arguments</th>
</tr>
</thead>
<tbody>
<tr>
<td>23 22c</td>
<td>new-array vA, vB, type@CCCC</td>
<td><code>A:</code> destination register (8 bits)<br/>
<code>B:</code> size register<br/>
<code>C:</code> type index</td>
</tr>
</tbody>
</table>
<h2>Constraints</h2>
<ul>
<li>
A and B must be valid register indices for the current stack frame.
</li>
<li>
Register vB must not contain a reference value.
</li>
<li>
Register vB must not be part of a register pair.
</li>
<li>
C must be a valid index into the type pool.
</li>
<li>
Type constant pool entry C must contain a valid array type descriptor.
</li>
</ul>
<h2>Behavior</h2>
<ul>
<li>
An attempt is made to get a reference to the class K the name of which is
contained in type pool entry C.
</li>
<li>
If K has not been loaded and resolved before, it is being loaded and
resolved. All exceptions that are possible during class loading can occur at
this point.
</li>
<li>
An attempt is made to create a new instance I of K and length B. All
exceptions that are possible during instantiation can occur at this point.
</li>
<li>
All elements of the new array are initialized to null (for object arrays) or
0 (for numeric arrays) or false (for boolean arrays).
</li>
<li>
A reference to the new array is moved to register vA, that is, vA' = I.
</li>
<li>
If v(A-1) is the lower half of a register pair, v(A-1)' becomes undefined.
</li>
<li>
If v(A+1) is the upper half of a register pair, v(A+1)' becomes undefined.
</li>
</ul>
<h2>Exceptions</h2>
<ul>
<li>
NegativeArraySizeException if vB < 0
</li>
<li>
All exceptions that are possible during class loading can occur.
</li>
<li>
All exceptions that are possible during instantiation can occur.
</li>
</ul>
