This section provides examples of how to create Bytes instances with different types of underlying data structures. Creating a Bytes instance which wraps an on heap byte array: Bytes which wraps an on heap byte[] Bytes<byte[]> bytes = Bytes.allocateElasticOnHeap(); byte[] underlyingBytes =...
Alternatively, you can use the shortcut syntax to create and initialize an array: int[] anArray = { 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 }; Here the length of the array is determined by the number of values provided between braces and separated by commas. You can a...
}publicstaticvoidchange(int[] array){// 将数组的第一个元素变为0array[0] =0; } 输出: 1 0 解析: 看了这个案例很多人肯定觉得 Java 对引用类型的参数采用的是引用传递。 实际上,并不是的,这里传递的还是值,不过,这个值是实参的地址罢了!
