Inheritance - Java vs C++
Java: Singular inheritance via 'extends' keyword; interfaces are a form of is-a
C++: Multiple inheritance using : and ,

Java: No choice on polymorphism; methods are always virtual
C++: Polymorphism is actuated via keyword virtual

Java has no explicit pointers. However, a reference to a base class may refer to any subclass
  - The object declared is of the base class' type but can be referred to a subclass. 
	In that case the subclass' version of the overwritten method is invoked.

      Using chmod 644 <file> does the same for a file.

chmod <octalDig 1><octalDig 2><octalDig 3>
          user       group       world

Each <octalDig> has three possible values, read, write, execute. An octal digit can represent one, two, or all three.   

An octal number has a 3-digit binary representation, a value between one and seven.

7 = binary 111 = rwx  , i.e. each of the three ocvtal digits represents rwx where each is on or off.

e.g. 6 = 110 = rwx , for a file 644 means user can read and write, group and world can read only
  files to be kept private: 600
