Java provides several XML Parsers like DOM, SAX or JDOM and API javax.xml.parsers by using those we can easily read xml files in Java. DOM is quickest and easiest way to read XMlL file in Java.
you can use inputstream for reading the file java.io.fileinputstream and write the file using outputstream..

To open and view the contents of a GP file, you can use a GP file reader software. Simply download and install the GP file reader on your device, then open the software and select the GP file you want to view. The GP file reader will then display the contents of the file for you to read and interact with.
You need to use File class to create file in java and than Reader class implementation such as BufferedReder to read content.
When you save an HTML file, the contents of that file are written on the hard drive. This has the effect of changing the contents of the file. When you read and HTML file, the file remains unchanged on the disk.
Not possible. Always make backup copies.
Open it (open of fopen), read the data (read or fread), then close it (close or fclose).
I'm not sure what version of emacs I'm using, but when I go to select a (JavaScript) file, I just click the open button, then at the bottom of the window, you will see it read: file '/' (Let's say your java file is hello.java placed under /home/) you would type /home/hello.java to open it. It should work.
protect your file B by password. this will become a read only file
right click on the class file ,go to properties and change open with to notepad, and then it can be opened.. :) While that may work, it is almost impossible to read as it is. What I suggest is downloading a java decompiler, then open it with that. It will convert it to what you would see in a .java file, which you are able to read if you know java programming.
