The expansion of a document is the last piece of its name after the period (.). For instance, the Java source document expansion is “java” and you will see that the record name generally finishes with “.java”.

We can utilize this document name and augmentation rationale to recover the last piece of the record name and get the expansion of the record.


A Java source document contains source code related to an application created with the Java programming language, and the comparing Java source records are referred to by a Java application when a client demands a bunch of elements requiring information contained in the Java source record.

The substance of a Java source document might incorporate catalog areas of other program records required by the related application to give the client the arrangement of elements compared to specific functionalities mentioned by the client from the application.

These Java source records are coordinated with encoding principles utilized by Oracle for the J document design. Explicit gathering particulars restrictive to Oracle are likewise carried out into a Java source record. Documents annexed with the .j expansion are Java source records created with multi-stage similarity support, similar to the bigger Java program related to the Java source record. A Java application created with a J source record can be opened and mimicked utilizing the Oracle Java Virtual Machine programming. This program has adaptations produced for PCs running on Microsoft Windows-based frameworks, while one more rendition is expected for Mac stages.
