接触串口很久了，一直以来将都是将串口读取出来的数组转换成字符串通过string.contains()查找是否包涵目标数组，自己感觉low到爆，所以写了一个byte-buffer，测试还是蛮好用的。希望借鉴和大神补充改正。

 

import java.util.Scanner;public class BufTest {    public static void main(String aeg[]){        new BufTest().run();    }    private Scanner sn=new Scanner(System.in);    private Buffer buf=new Buffer(100,new byte[]{(byte) 0xaa,(byte) 0xee,(byte) 0xdd} ,new byte[]{(byte) 0xee,(byte) 0xaa,(byte) 0xdd});        public void run(){        while(true){            System.out.println("---------------------------INPUT---------------------------");            passString(sn.next());            System.out.println("+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++");            System.out.print("checkOut:");            printBytes(buf.checkOut());            System.out.println();            System.out.println("+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++");            for(int i=0;i
     
      bufSize||                    (endIndex>wIndex&&endIndex
      
       rIndex&&endIndex>wIndex)||                    (endIndex
       
        
         endIndex)?bufSize-rIndex+endIndex:endIndex-rIndex;        }        /*位置加一*/        public int moveNext(int index){            index++;            return index%=bufSize;        }        /*位置加size*/        public int moveNext(int index,int size){            index+=size;            return index%=bufSize;        }        /*是否可写*/        public boolean canWrit(int index){            index=moveNext(index);            return index!=rIndex;        }        /*是否可读*/        public boolean canRead(int index){            index=moveNext(index);            return index!=wIndex;        }        /* 返回当前位置是否等于将要比对的数组*/        public boolean findNext(int index,byte erq[],boolean isHead){            for(int i=0;i
