That means: the file where a class is stored.
No. The standard does not define nor require a file concept.
A (java) class file was not be made to be opened and modified by hand for the users. A class file is the resulting byte code of your java file compilation. This class file can be interpretaded for any jvm. To run your java class you only need to write these instructions in your command line. java [ options ] className [ arguments ... ] java -classpath D:\myprogram MyFileName one two three
You need to use File class to create file in java and than Reader class implementation such as BufferedReder to read content.
No. There can be multiple java classes in the same .java file, but the name of the file must match the name of the public class in the file.
If using 1 class per file as the standard, then it would be easier to understand that a partial class contains only a portion of the class definition in one file, while the other (may have more than one file) have the rest of the code belong to that class. One good example is the field definitions (data members) in one file, while the another file supply with behaviors that may not have anything to do with the data fields.

file class contain methods or functions that handle various file stream operations.
What i know is java we will use compiler when it want to get class file(file with .class extension) from java file(file with .java extension).
The java file has the actual JAVA code present in it,..i.e the entire coding is done in that file.. you can view it using any text editor.. After compiling it you get a class file of every class present in the java file When you open a class file in a text editor, you won't see anything that makes sence. You won't find the original code that you wrote in the java file. That is because a class file is a product of the compilation of a java file.
thank you
The name of the .java file should exactly match with the name of the public class in the file. Ex: public class Test { ..... } this file should be saved as Test.java

if we need a modifying ,sreach,delete a file so we need a DBMS

That's pretty vague. You're taking a class on it, so the answer should be whatever you're studding in class.
