Do I need to override enum's hashCode() and equals()?

Question

Hi all:
I have a enum type let's say it is
public enum Type
  ONE,
  TWO;
}If I want to compare the enum value to see if they are same value or not, let's say I have two:
Type a = Type.ONE;
Type b = Type.TWO;should I use a.equals(b) or (a == b) If I want to use it as another class's key field, and I want to override this class hashCode() and equals() methods.
Can enum Type return the correctly hash code?
For example the class is like:
public Class A
  Type type;
  pubilc boolean equals(Object other)
    // here skip check class type, null and class cast
    if(other.type.equals(this.type))
       return true;
    else
     return false;
  public int hashCode()
    int result = 31;
    result += 31 * result + type.hashCode() ;
   // can we get correct hash code from enum here?
    return result;
}

Answered by the test code by myself.
We can use either equals or (==) to see if they are the same value.
The enum's hashCode() use System.identityHashCode() to generate the hashCode and they are always correct
