2. What is the difference between java and polymorphism in java?
[tex]\large\pink{\boxed{Answer:}}[/tex]
•Inheritance vs polymorphism JavaInheritance is one in which a new class is created (derived class) that inherits the features from the already existing class(Base class). Whereas polymorphism is that which can be defined in multiple forms. ... Inheritance supports the concept of reusability and reduces code length in object-oriented
programming.
Answer:
Polymorphism in Java is a concept by which we can perform a single action in different ways. ... So polymorphism means many forms. There are two types of polymorphism in Java: compile-time polymorphism and runtime polymorphism. We can perform polymorphism in java by method overloading and method overriding.

Java Key.words vs. Identifiers
Java is a high-level, object-oriented programming language that was developed by James Gosling and his team of Sun Microsystems (1991). I remember that it was initially made with the purpose of designing a language for programs that could be embedded in consumer electric devices such as refrigerators. The name "Java" was inspired by the popular coffee beans of Java Island (Indonesia) that Gosling's team enjoyed drinking. No wonder Java has a logo of a coffee mug.
Java Key.wordsThese are words in Java that have a special purpose. They are predefined identifiers that you can use to identify the variables, classes, etc. you put in your code. You can't use them to represent the names of your variables, etc. Some of these key.words are the following:
[tex]\tt{public,\ class,\ char,\ int,\ boolean,\ float,\ long,\ double}[/tex]
Java IdentifiersThese are words you use to represent your variables, methods, classes, etc. You decide on what identifier you want to use. However, you must take note that these tokens are case-sensitive. Meaning, the identifier "Hello" is not the same as "hello".
For example,
[tex]\text{\tt{//for those who already have basic knowledge of java}}[/tex]
[tex]\text{\tt{//java file na.me}}[/tex]
[tex]\text{\tt{Hello.java}}[/tex]
[tex]\text{\tt{//your code inside Hello.java}}[/tex]
[tex]\text{\tt{public class hello}}[/tex]
[tex]\text{\tt{\{}}[/tex]
[tex]\text{\tt{//statements}}[/tex]
[tex]\text{\tt{\}}}[/tex]
The code above will result in an error because your identifier "hello" is not the same as your file name "Hello". Instead, it must be like this:
[tex]\text{\tt{//your code inside Hello.java}}[/tex]
[tex]\text{\tt{public class Hello}}[/tex]
[tex]\text{\tt{\{}}[/tex]
[tex]\text{\tt{//statements}}[/tex]
[tex]\text{\tt{\}}}[/tex]
Rules for Java IdentifiersYou already know that it is case-sensitive so you have to be careful in writing it. It must begin with a letter (either an upper case or lower case) or an underscore (_), or a dollar sign ($). You may also use numbers from 0-9.
However, you must not use underscore before the start of words read or write. Example: _read, _write. They mean something in java.
Personally, I write identifiers in lower cases such as [tex]\text{\tt{totalsum}}[/tex], [tex]\text{\tt{num}}[/tex], and [tex]\text{\tt{main}}[/tex]. There are also times when my identifiers are composed of two or more words combined, I write the first letter of the first word in a small case and the first letter of the second word and so on in upper cases. Examples, [tex]\text{\tt{greatestNum}}[/tex] and [tex]\text{\tt{daysLeft}}[/tex].
Why are rules or guidelines important in using Java identifiers?These help in making your Java code clear and easy to read and understand. These could lead you to better collaboration and more efficient code reviews.
They reduce the possibility of errors or bugs during the compilation of your code.
They allow the coders to understand the functionality of a specific identifier and could aid them in debugging, optimizing, and maintaining the code over time.
