short 转byte[]
int temp = val;
??byte[] bt=new byte[2];
??for (int i = 0; i < 2; i++)
??{
??? bt[i]=new Integer(temp & 0xff).byteValue();// 将最低位保存在最低位
??? temp = temp >> 8; // 向右移8位
??}int?转byte[]
int temp = v;
??byte[] bt = new byte[4];
??for (int i = 0; i < bt.length; i++)
??{
// 将最低位保存在最低位 例如90 输出[5A][00][00][00]
???bt[i] = new Integer(temp & 0xff).byteValue();
???temp = temp >> 8; // 向右移8位
??}long?转byte[]
long temp = v;
? byte writeBuffer[] = new byte[8];
??for (int i = 0; i < writeBuffer.length; i++)
??{
???writeBuffer[i] = new Long(temp & 0xff).byteValue();???// 将最低位保存在最低位
???temp = temp >> 8;???// 向右移8位
??}String 转byte[]
String s=new String("测试");
