请看下面的例子：
- byte b=(byte)255;
- //b>=0 && b<=255
- System.out.println("b1="+b);
- System.out.println("b2="+(b&0xff));
- //-------------------------------
- short ss=(short) 65535;
- //ss>=0 && ss<=65535
- System.out.println("ss="+ss);
- int rr=(ss)&0xffff;
- System.out.println("rr="+rr);
- //使用例子：
- byte [] bb=new byte[2];
- bb[0]=(byte)(ss>>0);
- bb[1]=(byte)((ss>>8));
- int result=((short)((bb[0]&0xff)| (bb[1])<<8))& 0xffff;
- System.out.println("result="+result);
- //-------------------------------
- long ll=4294967295L;
- //ll>=0 && ll<=4294967295L
- int ii=(int)ll;
- System.out.println("ii="+ii);
- long l2=(ii & 0xffffffffL);//0xffffffffffffffffL
- System.out.println("l2="+l2);
