Java full notes for beginners:
Abstraction, encapsulation, inheritance, and polymorphism. Java’s architecture neutrality allows for the
size of a data type to depend on the compiler’s architecture. Abstraction is achieved by hiding the
implementation details and only showing the essential parts. Inheritance allows for the acquisition of
the properties of one class by another. Polymorphism refers to the ability to perform the same task in
different ways, and it can be achieved through method overloading and method overriding. In Java
programming, everything is treated as a class, and all objects must be implemented through a class
within a package. The “import” keyword is used to access classes within a package, while the “this” and
“super” keywords are used to represent the current object or access methods in an inheritance concept.
Try so tribe is used in exceptional handling so if any exception is raised then to raise the exception or to
catch the extra exception we ‘ll use this try catch so we will write this try and catch block. Final keyword
which is similar to our constant so if one value is assigned to the final keyword then that variable will be
having that that that holds the value throughout the program so for that this final keyword is used.
These are the different keywords used in java programming and one thing we have to remember is all
the keywords should be written in lowercase characters so while doing the program we will able to see
the importance of all these keywords so naming conventions are rules to be followed by giving a name
to an identifier. All these keywords are related to the classes to import the class to and this is for
exception handling. In java programming we are able to create a class or methods or objects or variables
so for everything we have to give some name so what are the rules to be followed by giving a name to
the these classes or methods. The name should not match with the keywords the first and foremost
thing so irrespective of this identifier we must follow this rule.
Features of Java are constantly being improved while remaining backward compatible. Additionally,
some versions of Java have long-term support such as version 17. With new features being added every
six months, there is always something new to explore in the world of Java.
Can teach you more languages in this course but I ‘d rather talk about Java now so I ‘d like to thank you
for your time “ Java is so famous because Java has multiple features which helps it to be used in the
Enterprise Market”and then I hit the return key and then I type in “print(“Hello, World!” and then I hit
the return key and then I type in “print(“Hello, World!”
