本文整理了Java中ucar.ma2.Array.arraycopy()方法的一些代码示例，展示了Array.arraycopy()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Array.arraycopy()方法的具体详情如下：
包路径：ucar.ma2.Array
类名称：Array
方法名：arraycopy

Array.arraycopy介绍

[英]Cover for System.arraycopy(). Works with the underlying data arrays. ArraySrc and ArrayDst must be the same primitive type. Exposed for efficiency; use at your own risk.
[中]覆盖系统。arraycopy（）。使用底层数据数组。ArraySrc和ArrayST必须是相同的基元类型。为效率而暴露；使用风险自负。

/**
 * Create a new Array by copying this Array to a new one with given shape
 *
 * @param shape the new shape
 * @return the new Array
 * @throws IllegalArgumentException new shape is not conformable
 */

 Array result = factory(this.getDataType(), shape);
 if (result.getSize() != getSize())
  throw new IllegalArgumentException("reshape arrays must have same total size");
 Array.arraycopy(this, 0, result, 0, (int) getSize());
 return result;
