The first thing in an enum have to be the declaration of the possible values.

public enum BooleanEnum
{  
  False(0), True(1);    

  private final int value;

  static
  {
    BooleanEnum[] arrayOfBooleanEnum = new BooleanEnum[2];
    arrayOfBooleanEnum[0] = False;
    arrayOfBooleanEnum[1] = True;
  }

  private BooleanEnum(int arg3)
  {
    this.value = arg3;
  }

  public int getValue()
  {
    return this.value;
  }
}

Unless there is more to your enum, though, I'd just use java.lang.Boolean.

Use

java.lang.Boolean.TRUE, 
java.lang.Boolean.FALSE

instead

Actually The body of an enum type may contain enum constants. An enum constant defines an instance of the enum type.

What you are trying to is You aren't gonna need it.

Just use a simple Boolean almost it self acts as ENUM for true false types.

Use Boolean.valueOf();
