Vary the channel content a little, post a bit more often, and I'm sure you'll gain a bigger following. You have quality videos and lots of potential. Keep up the good work! :)

    Public variables/methods can be accessed from any class or package.
    Default variables/methods can only be accessed from within the same class or within the same package - a default variable/method cannot be accessed from a class in a different package.

    "So the only difference between default and public is that public you write it in front" - that's not correct. Default fields are only visible to classes in the same package while Public fields are visible to any other class
    If you leave the access modifier for hours and minutes as 'default' in the class 'Access1', you won't be able to access those fields in the class 'Access3', which is in another package.

    Allover.⬇️
    1. Default. Access within the package only.
    2. Public. Access everywhere even outside the
    package .
    3. Private. Access Only in class .
    4. Protected. Access in 1 package only but if you use
    extends keyword then it access in outside the
    package.
    But there outside the package Object must be that
    2nd package's class

    Maybe worth mentioning the assignment issues with different access modifiers.
    E.g at 'protected', you can assign a different value to a variable inside the same package, but while on a extended class - you cant change the value of the original class's variables.
    I know I explain terrible, maybe Alex can do it better :))
