It represents the number of dimensions of the array to be created. The operand stack must contain <i>dimensions</i> words, which must be of type <code>int</code> and nonnegative, each representing the number of components in a dimension of the array to be created. The <i>count1</i> is the desired length in the first dimension, <i>count2</i> in the second, etc.<p><a name="104839"></a>All of the <i>count</i> values are popped off the operand stack. 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">(§3.6)</a>, where the value of the index is (<i>indexbyte1</i> << 8) | <i>indexbyte2</i>. The item at that index in the constant pool must be a <code>CONSTANT_Class</code> <a href="ClassFile.doc.html#1221">(§4.4.1)</a>. The symbolic reference is resolved <a href="ConstantPool.doc.html#65204">(§5.1.3)</a>. The resulting entry must be an array class type of dimensionality greater than or equal to <i>dimensions</i>.<p><hr><!-- This inserts footnotes--><p><a href="VMSpecTOC.doc.html">Contents</a> | <a href="Instructions2.doc159.html">Prev</a> | <a href="Instructions2.doc161.html">Next</a> | <a href="Mnemonics.doc.html">Index</a><p><font size=-1>Java Virtual Machine Specification (HTML generated by dkramer on February 25, 1997)<br><i><a href="Copyright.doc.html">Copyright © 1996 Sun Microsystems, Inc.</a>All rights reserved</i><br>Please send any comments or corrections to <a href="mailto:doug.kramer@sun.com">doug.kramer@sun.com</a></font></body></html>⌨️ 快捷键说明
