Files that contain the .java file extension are program files that have been written in the Java programming language. Sun Microsystems began development of the Java programming language in 1990. In 2009 the Oracle Corporation bought Sun Microsystems.
The Java programming language uses an object-orientated approach to programming. A file with the .java extension may contain a single Java program or a variety of source code files that are combined into a single executable app. Many compilers use these files to create Java source code. Usually when a file contains the .java file extension, it contains a single page of plain text code written in the Java language.
