Java中字节转为int publicstaticintbyteArrayToInt(byte[] bytes){intn=0;for(inti=0; i <4; i++) { n += bytes[i] << i*8; }returnn; } 字节缓冲流 基本知识 //1.分配一个指定大小的缓冲区ByteBufferbuf=ByteBuffer.allocate(1024);
flash.utils.ByteArray.writeUTF(value:String):void 将UTF-8字符串写入字节流。先写入以字节表示的UTF-8字符串长度(作为16位整数),然后写入表示字符串字符的字节。 那么在java后端就可以根据规则读取写入的字符串了。 public static String getString(ByteBuffer packDataBuff) ...

A summary string hashCode public int hashCode() Returns the current hash code of this buffer. The hash code of a byte buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1. Because buffer hash cod...
