接下来,我们用序列图展示deepCopy方法的调用过程: Copy ByteArrayOutputStreamDeepCopy MethodOriginal ByteArrayOutputStreamCopy ByteArrayOutputStreamDeepCopy MethodOriginal ByteArrayOutputStreamdeepCopy(A)A.toByteArray()byte[] datanew ByteArrayOutputStream()C.write(data)Return C 结论 通过以上示例,我们可以清...

for (j=0; j<STREAM_ARRAY_SIZE; j++) a[j] = b[j]+scalar*c[j]; 稍微阅读代码就知道STREAM并不是开箱即用的类型, 而需要根据不同机器进行配置, 我们第一次测试并没有考虑这点: * 1) STREAM requires different amounts of memory to run on different ...
