java byte数组写入本地文件，那这个文件是二进制文件吗？不是的话，是什么文件？跪求解答啊

byte是十进制的数字。。

给你看个例子：

public class Test {

public static void main(String[] args) {

String str = "b"

byte[] bytes = str.getBytes()

for(byte b:bytes){

System.out.println(b)

System.out.println(Integer.toBinaryString(b))

}

}

}

private void method()

{

byte[] buffer = { 22, 2, 0, 0, 0, 0, 0, 0, 0, 150, 0, 80, 0, 160, 0 }

using (FileStream fs = new FileStream(@"C:\BloodPressure.bin", FileMode.CreateNew, FileAccess.ReadWrite))

{

using (BinaryWriter writer = new BinaryWriter(fs))

{

writer.Write(buffer, 0, buffer.Length)

}

}

}

这样写经过了验证是ok的.
