Java Language Source Code Format | Oracle | Developer Files |
The JAVA file extension is used by the Oracle Java platform to indicate a source code file written in the Java programming language. Java source files typically end with the .java extension and are compiled into class files which can contain multiple files combined into one, ending with the extension .class. Although class files are normally represented in binary format, they can also be edited as plain text documents and compiled into working Java programs.
Programming Application Requirements
In order to create a .java file, one requires an Integrated Development Environment (IDE) such as IntelliJ IDEA, Eclipse, or Apache NetBeans. Multiple editors, such as Visual Studio Code and Atom, support Java source code editing as well. After an IDE is installed, users can create the .java files and begin the process of writing code or ‘programming’. The file can be subsequently saved with the.java extension, prompting a compiler to convert it into the.class format. Other file extensions used in Java programming include .jar, .ser, and .jsf.
Compiling Into Binary Format
The process of ‘compiling’ a .java file involves converting it from plain text code into a type of language known as Binary, so that it can be read and understood by machines. This process is handled automatically by compilers within the IDE or other command line tools for building executable programs from source code files. The compiled file is saved in this binary form using the extension .class. These actions ensure that the code is formatted correctly so that any errors or bugs are avoided when running a program.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .JAVA) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .JAVA extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .JAVA file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .JAVA extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .JAVA extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .JAVA file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .JAVA file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .JAVA file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .JAVA file) will be extended to the maximum.
It is also good to check
- if the .JAVA file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
