JAVA File Extension

Have a problem opening a .JAVA file? We collect information about file formats and can explain what JAVA files are. Additionally we recommend software suitable for opening or converting such files.

What is the .JAVA file type?

The .java extension is consistently and universally associated with Java and assigned to Java source-code files. Java is a very popular high-level object-oriented computer programming language, similar to C++. Java provides platform-independent runtime environment (a Java Virtual Machine, JVM) so that a Java program developed in GNU/Linux will run under Windows. Small Java applications (applets) are widely used on the Web.

A .java file is a plaintext file that contains a source code of a program in the Java programming language. Such JAVA files can be opened, viewed, edited and saved with any text editor or, preferably, within a Java IDE (Integrated Development Environment).

Plaintext .java files cannot be directly run on a JVM, they have to be pre-compiled into a so-called 'bytecode' first and assigned the .class extension. Such pre-compiled .class source code can be interpreted and run by any Java VM.

A Java compiler is required in order to compile a .java source-code file into a runnable .class.
