Consider this Java declaration which is made within the class definition of a hypothetical class called classx. public static final int HOURS_IN_DAY = 24; Which two of these statements about the variable HOURS_IN_DAY are true? Select one or more: HOURS_IN_DAY is an instance variable. HOURS_IN_DAY has been initialised at its point of declaration. It would have been possible to have initialised its value in the classx constructor. HOURS_IN_DAY is only accessible from within classx. There will be different copies of HOURS_IN_DAY for all instances of classx. The value of HOURS_IN_DAY cannot be changed it is effectively a constant. In order to access HOURS_IN_DAY from an unrelated class you need to write classX.HOURS_IN_DAY, or the code will not compile. HOURS_IN_DAY is a class variable
