This document provides an overview of object-oriented programming concepts in Java including inheritance, polymorphism, abstraction, and encapsulation. It also discusses control structures like if/else statements and switches as well as repetition structures like while, do-while, and for loops. Arithmetic operations in Java like addition, subtraction, multiplication, and division are also mentioned.

1. Java Object Oriented
M Iqbal Al Ghazaly
This beginner Java tutorial describes fundamentals of
programming in the Java programming language.

2. OOP
Object Oriented Programming (OOP) is a programming method that
based from object. Small think from OOP is an object collection that
interact with each other and excange an information
Inheritance
Polymorphism
Abstraction
Encapsulation

3. Inheritance
A class that is derived from another class is
called a subclass . The class from which the
subclass is derived is called a superclass .

5. Polymorphism
The word "polymorphism" means "many
forms". It comes from Greek word "poly"
(means many) and "morphos" (means form).

7. Abstraction
Abstraction is a very important element of object oriented
software development and is used in the design phase to
find a suitable hierarchy for a set of classes.
Abstraction refers to the ability to make a class abstract in
OOP. An abstract class is one that cannot be instantiated.
All other functionality of the class still exists, and its
fields, methods, and constructors are all accessed in the
same manner. You just cannot create an instance of the
abstract class.

8. Encapsulation
Encapsulation is one of the four fundamental OOP concepts.
The other three are inheritance, polymorphism, and
abstraction.
Synonym: information hiding
Encapsulation is one of the most important characteristics of
an object oriented system.

9. Repetition Control Structures
Decision control structures are Java statements that
allows us to select and execute specific blocks of
code while skipping other sections.
If statement
Switch statement
Repetition Control Structures

10. If statement
The if-statement specifies that a statement (or block of
code) will be executed if and only if a certain
boolean statement is true.
Devided by 3,they are:
If-else
If-else-if
If-else-else-if

11. Switch statement
Another way to indicate a branch is through the
switch keyword. The switch construct allows
branching on multiple outcomes.

12. switch( switch_expression ){
case case_selector1:
statement1;
statement2;
break;
case case_selector2:
statement1;
statement2;
break; default: statement1;statement2;
break;
}

13. Repetition Control Structures
Repetition control structures are Java statements that
allows us to execute specific blocks of code a
number of times. There are three types of repetition
control structures, the while, do-while and for loops.

14. While loop
The while loop is a statement or block of statements
that is repeated as long as some condition is
satisfied.
while( boolean_expression ){
statement1;
statement2;
...
}

15. do- while
The do-while loop is similar to the while-loop. The
statements inside a do-while loop are executed
several times as long as the condition is satisfied.
do{
statement1;
statement2;
...
}while( boolean_expression );

16. For-loop
The for loop, like the previous loops, allows execution
of the same code a number of times.
for (InitializationExpression; LoopCondition; StepExpression){
statement1;
statement2;
...
}

17. Arithmetic in java
Arithmetic has a job such as mathematics, it uses for
doing mathematic's operation, such as pluses,
division, minuses, and times
