Reading file bit by bit

[John Wilson]

Hi
I am trying an program, I have one byte, in one byte each one of the 8bits means a training for an employee in my data.

The left most bit - orientation training
The 2nd bit  -  management training
The 3rd bit  - technical training
The 4th bit  - operations training
The 5th bit  - administrative training
The 6th bit  - quality control training
The 7th bit - sales training
The 8th bit -  safety training

The main problem is I can not read what training an employee has.

I think it is better if you read the data in bytes and then operate on the bytes to get the information.

I am not used to operating with bytes and so I do not try that. The byte I have is a certain value. I think I would not be able to do it. Since the dat allows a employee to have more than one type of training. So, I have to state all types of possibility.

Hi
Even I am not an expert of doing this programs. But still this may help you.

public enum Trainingmsks {
  ORI(0x80),
  MAN(0x40),
  TEC(0x20),
  OPE(0x10),
  ADMIN(0x08),
  QUA(0x04),
  SAL(0x02),
  SAF(0x01);
  
  private int msk;
  private Trainingmsks(int msk) {
    this.msk = msk;
  }
  
  public int getmsk() {
    return msk;
  }
  
  public boolean istra(int test) {
    return (test & msk) != 0;
  }
}

Hi
The above cod is perfect, you can also try this code. Hope this will help you

public class train {
    public enum trainType {
        ori, mana, tech, opera,
        admin, qty,sal, safe
    }
	
    private EnumSet<trainType> types = EnumSet.noneOf(trainType.class);
	
    public train(byte b) {
        for(trainType t :trainType.values()) {
            if((b & 1 << t.ordinal()) != 0) {
                types.add(t);
            }
        }
    }
	
    public Set<trainType> getCanDo() {
        return Collections.unmodifiableSet(types);
    }
	
    public Set<trainType> getCantDo() {
        return EnumSet.complementOf(types);
    }
	
    public void add(trainType newT) {
        types.add(newT);
    }
	
    public boolean istrain(trainType testT) {
        return types.contains(testT);
    }
	
    public static void main(String[] args) {
        train test = new train((byte)0xf2);
        System.out.printf("Can do: %s%n", test.getCanDo());
        System.out.printf("Can't do: %s%n%n", test.getCantDo());
		
        test.add(trainType.tech);
        for(trainType type :trainType.values()) {
            System.out.printf("Can %s: %s%n", type, test.istrain(type));
        }
    }
}
