groovy - 无法在 groovy 中创建字节数组的数组

Question

当我尝试在 groovy 中创建字节数组数组时出现错误。我的代码是:

def patch0 = [0, 2, 4, 8, 16] as byte[];
def patch1 = [0, 3, 6, 12, 24] as byte[];

def patches = [patch0, patch1] as byte[];

我得到的错误是:

GroovyCastException: Cannot cast object '[B@7630e551' with class '[B' to class 'java.lang.Number'

Answer 1

我认为您的问题是，当您在第三行将数组转换为 byte[] 时，Groovy 试图将每个数组转换为字节。如果将该转换更改为二维字节数组，错误就会消失。

def patch0 = [0, 2, 4, 8, 16] as byte[]
def patch1 = [0, 3, 6, 12, 24] as byte[]

def patches = [patch0, patch1] as byte[][]
