将while循环更改为for循环

Question

我正在尝试将其更改为循环进入for循环，并且我没有特别远。我是编程的新手，如果这是一项微不足道的任务，请道歉。

while (read < fileBytes.length
       && (numRead = diStream.read(fileBytes, read, fileBytes.length - read)) >= 0)
{
    read = read + numRead;
}

Answer 1

尝试使用它：

start_value = //....
for (read = start_value; read < fileBytes.length 
        && (numRead = diStream.read(fileBytes, read, fileBytes.length - read)) >= 0; 
        read += numRead) {

    //Your actions

}

Answer 2

我是C＃程序员，但我会编写与您需要的代码非常相似的代码。

for (int read = 0; read < fileBytes.length;) {
    numRead = diStream.read(fileBytes, read, fileBytes.length - read);
    if (numRead >= 0) {
        read = read + numRead;
    }
}

Answer 3

for(numRead = diStream.read(fileBytes, read, fileBytes.length - read);
read < fileBytes.length && numRead >= 0;
numRead = diStream.read(fileBytes, read, fileBytes.length - read)) {
      read = read + numRead;
}
