OBJECT ORIENTED PROGRAMMING IN JAVA (STANDARDS / .OPERARTORS/ CLASS AND OBJECT)
The Java Programming Language is based on an OOP Methodology and that has different kinds of point such as called Java Class hierarchy
- Object
- Class
- method
- Variable
Do you Know Standards of java?
So , above I mentioned java programming language is an OOP based language and its standards are Combination with Variables, Class, and method
Now, I will tell:
how to identify these standers;
Car - class
First letter is Uppercase of the word It's Called "Class".
car - variable
First letter is Lowercase of the word it's called "Variable"
car() -method
First letter is a lower Case and after the word with Parameters it's called "Method".
Then Now, I explain:
How to create java Print Statement
System is a Class ,out is a variable and print () is a method.
above mentioned statement use to the Dot Operator ( its use for the Calling) ("Hello World") is a print part and important thing is end of the statement must be added ;. Semi colon for the end .
I explained java Print Statement and now I move on other part such as Scope Identification is a when you declare a variable, look for the closest enclosing curly brackets { } – its called scope Identification.
Ex- class A{ 1
Integer.int = "2"
System. out. print (A. a) ;
public void test(){2
}2
}1
Point of Especial...….
String b = "2";
It s a Simple assignment operator. Assigns values from right side operands to left side operand. Its meaning is a String b="2" assign value of "2" into String b.
String a = "2"
String b= "1"
== This is a Equalization Operator ,my mind , actually this operator use Checks the values of two operator are equal or not, if yes then condition becomes true.
(a==b) is an incorrect.
CLASS AND OBJECT
This is a most important part in my Article ,so
"What is Object and class" ?
I will explain;
An object is a features and functions combination.an object is stored in properties (variables), while behaviors (functions) display the object's behavior. Objects are created from templates and which are also known as classes.
What a class does is that if there are more objects, they are taken under one and other special thing is that even if the values are different, it is possible to create a class using features and functions.
Thank you.
