The unsigned <i>indexbyte1</i> and <i>indexbyte2</i> are used to construct an index into the constant pool of the current class <a href="Overview.doc.html#17257">(&#167;3.6)</a>, where the value of the index is (<i>indexbyte1</i> << 8) | <i>indexbyte2</i>. The item at that index must have already been resolved to a class type. A new instance of that class is created, and the instance variables of the new object are initialized to their default initial values (<a href="Concepts.doc.html#15858">&#167;2.5.1</a>). The <i>objectref</i>, a <code>reference</code> to <em>the instance, </em>is pushed onto the operand stack.<p>

The opcode of this instruction was originally <i>new</i>. The operands of the original <i>new</i> instruction are not modified.<p>
