如何从msb开始获取特定位置的位值?
问题描述：
我以前从未在Java中使用过位，因此问题如下: 我有
I never worked with bits in Java before, so the question is the following: I have
byte a=254;
如何从msb位置开始从该字节中获取位?
How to get a bits from this byte, starting from msb position?
If position == 0 it returns 1
If position == 7 it returns 0
提前谢谢
答
int getBitFromMSB(byte x,int position){
return (x >>> (7 - position)) & 1;
}
