在字节数组中查找单行注释 [英] Find single line comments in byte array

问题描述

是否有可能在从文件读取到字节数组的行中找到 // 的实例，然后从 //中截取 到行尾吗？我正在尝试

Is it possible to find instances of // in a line read from a file into a byte array and then "snip" from // to the end of the line out? I'm trying

FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[8 * 1024];
int read;

while ((read = fis.read(buffer)) != -1) 
{
    for (int i = 0; i < read; i++) 
    {
        if (buffer[i] == '//')
        {
            buffer = buffer[0:i];
        }
    }
}

但我得到 处的字符常量常量如果上的（buffer [i] =='//'） '//'部分。我是在做错什么，还是这是不可能的？

but I'm getting Invalid character constant at if (buffer[i] == '//') on the '//' part. Am I doing something wrong, or is this just not possible?

推荐答案

老式解决方案

for (int i = 0; i < read-1; i++) 
    {
        (if (buffer[i] == '/') && (buffer[i+1]== '/'))
        {
            buffer = buffer[0:i];
        }
    }
