OutputStream、InputStream是所有字节流的超类,所谓字节流就是一个字节一个字节的读取,类似于c中的二进制读取方法
java.io.OutputStream
Method
void write(int b)
Writes the specified byte to this output stream
void write(byte[] b) // String 类的方法, byte[] b = "中国".getBytes();
Writes b.length bytes from the specified byte array to this output stream.
void write(byte[], int offset, int len)
Writes len bytes from the specified byte array starting at offset off to this output stream.
OutputStream out = new FileOutputStream("E:/a.txt"); out.write(97); // 写下二进制的97,文本编辑器读出二进制97,查询本机编码表,得出a byte[] b = {-43,-44}; // 赵 out.write(b); out.close();
