Why the output of this code is 0? Protected variables cannot be accessed from Main Class. Can somebody explain?

Answer 1

In java, we can access Protected modifier in same package as well as sub class package.

Answer 2

If you want to prevent an access from inside the package, then chose the "private" modifier.
See here a nice table:

Answer 3

The output is 0 because you have not initialized any values to x and y. The default value of x and y is 0.
So t.x+t.y= 0+0= 0
Initialize values to x and y and try it.

protected members can be accessed from within the same class+ different class of same package+ subclass of same package+ subclass of different package

Answer 4

Orango Mango protected modifier is accessible in the same package[consider the code you wrote is in the same file] https://docs.oracle.com/javase/tutorial/java/javaOO/accesscontrol.html

Answer 5

Protected is not default.
Protected gives access for subclasses in same and other package.
Default = no modifier: gives only access for subclass in same package.

Answer 6

KODER999 , yes, that's what I wrote. But from all packages.
And if you don't use any modifier (default) only from subclasses in same package.
So "no modifier" or default is a "stronger" protection as using "protected".

Answer 7

KODER999 public is from all packages, but not only from subclasses of the class.
Maybe you will have a look at my answer above here. There is a table on stackoverflow.com that shows the behavior.

Answer 8

I guess that's because they placed in one package. Google it, maybe you'll get it better
