本文整理了Java中java.lang.reflect.Array.get()方法的一些代码示例，展示了Array.get()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.get()方法的具体详情如下：
包路径：java.lang.reflect.Array
类名称：Array
方法名：get

Array.get介绍

[英]Returns the value of the indexed component in the specified array object. The value is automatically wrapped in an object if it has a primitive type.
[中]返回指定数组对象中索引组件的值。如果对象具有基元类型，则该值将自动包装在对象中。

代码示例

代码示例来源：origin: libgdx/libgdx

/** Returns the value of the indexed component in the supplied array. */
static public Object get (Object array, int index) {
  return java.lang.reflect.Array.get(array, index);
}

代码示例来源：origin: org.mockito/mockito-core

public static Object[] createObjectArray(Object array) {
    if (array instanceof Object[]) {
      return (Object[]) array;
    }
    Object[] result = new Object[Array.getLength(array)];
    for (int i = 0; i < Array.getLength(array); i++) {
      result[i] = Array.get(array, i);
    }
    return result;
  }
}

代码示例来源：origin: square/retrofit

@Override void apply(RequestBuilder builder, @Nullable Object values) throws IOException {
  if (values == null) return; // Skip null values.
  for (int i = 0, size = Array.getLength(values); i < size; i++) {
   //noinspection unchecked
   ParameterHandler.this.apply(builder, (T) Array.get(values, i));
  }
 }
};
