Let me start by saying I have never really worked with bits before in programming. I have an object that can be in 3 states and I want to represent those states using a 3 bit array.
For example:
I have a race car and it can go forward,left, and right at a stand still the bits would be 000
If the car was moving forward the bits would be 010 if forward and left it would be 110 etc...
How would I set the bits and how could I read them back to get the values?
Answer
I would suggest using BitSet along with enum's
enum State { LEFT, RIGHT, FORWARD,STAND_STILL}
BitSet stat=new BitSet(4);
void setLeft() // and so on for each state
{
stat.set(State.LEFT);
}
boolean isLeft()
{
stat.get(State.LEFT);
}
void reset() //reset function to reset the state
{
stat.clear();
}
