Answer 1

I added two versions:
override toString()
or write an own print method

Answer 2

Can you give an example of an expected output?

Answer 3

Here you find more about the toString() method: https://www.google.de/amp/s/www.geeksforgeeks.org/overriding-tostring-method-in-java/amp/

Answer 4

Humayoon Rafei No. Only printing the object (without overriding toString()) would give you something like this: A[@24224] -> the class name and inside the brackets a hashcode.

Answer 5

here it is but i dont want to call each line i just want to call one thing and it would print all of it as below can a constructor do that ???

Muhammadi
abdullah
122546255
Math
Biology
11111111

Answer 6

so there isnt any single command line to print all contents encapsulated in an object not taking help of tostring or making print function????
