Those files have the extension .java
'.java' files contain java source code. One can access these files on windows by using 'notepad'.
.class is the extension of a java byte code file.
.jar files contain byte-code compiled to run on the Java Virtual Machine.
Java source files have the .java extension, compiled Java class files have the .class extension.
The only reason to convert a .class file to a .java file would be to attempt to reverse engineer a piece of Java code. Disadvantages of this would include near-incomprehensible code being produced by the reverse engineering program.

Without Java files, we wouldn't be able to program in Java. And some of us find Java to be an important programming language.

Java does not require header files like C/C++.
The input is source code (MyClass.java) and the output is bytecode (MyClass.class).Generally, Java compilers receive as input .java source code files, and output .class binary files which are then executed by the Java Virtual Machine (JVM) executable.Some Java compilers output binaries in machine code that can be directly executed.The input is a source file with the java extension. (i.e. HelloWorld.java) The output is the byte code file with the class extension. (i.e. HelloWorld.class)Input:1. Most compilers take as input the source program which is in a particular programming language.2. Compilation Switches ( special arguments that tell the nature of compilation and structure of target code).3. Supporting Files (Library Files) such files help in the execution and translation of a programOutput:1. Program List file.2. Target Code. Target code is the equivalent of the source code but in another language
Source code written in Java is simple. There is no preprocessor, no #define and related capabilities, no typedef, and absent those features, no longer any need for header files. Instead of header files, Java language source files provide the declarations of other classes and their methods.
Java doesn't use header files.
The standard place to download the main Java files is the Oracle Java site. You can separately download different IDEs, depending on your preference. I am not sure what "unnecessary files" are contained in any of these downloads; however, you can sometimes choose different options, depending on your specific needs. For example, Oracle Java site contains both a version for the end-user (with less files), and one for developers/programmers (with more files).
