Object-oriented programming concepts
Class / object definitions
Static / non-static
Encapsulation

Java API documentation
Reading an API method summary

Method signatures
Method calls
Tracing an array through a sorting algorithm
Implementation of standard class variables and methods

Thank you.

Explanation / Answer

The explanation required is as follows:

1) Class: Its basically a real world entity having data members and member functions. For example "Bird" is a class

2) Object: Its basically a instance of Class.

3) The various object oriented programming concepts are:
   i) Abstraction: Object oriented programming provided abstract view. Here we need not think how base class is working we just inherit it if we want to use it.
   ii) Inheritance: In these property one class inherit the properties of another class.
   iii) Encapsulation: Its refers to the data security. In object oriented programming we have various access specifier to protect the data.
   iv) Polymorphism: It says that one fuction may behave differently in different conditions.
  
4) Static Data Member: Static data member store in the data segment of the memory. And all the object share the same static data member.

5) Non Static Data Member: These data member stored in stack or in the heap and each object having seperate non static data member.

6) Constructors: In object oriented programming, constructors are used to initialize the data member of the class. Constructors are being called when ever we create the object
There are three types of constructors:
   i) Default
   ii) Parameterised
   iii) Copy Constructor
