JAR Archive

β‡’ Category:Compressed Files

πŸ“Œ One more apparent assignment of the .J extension term corresponds to the compressed file archive pattern composed and opened with JAR, a notable technological successor to the ARJ file compression utility (which initially served for constructing .ARJ archive packages). JAR tool is accessible and distributed as a 32-bit Windows edition and pretty extinct 16-bit console DOS revision, operating in command prompt mode. This specific .J format definition is not related or conjugated anyhow to the .JAR technological principle, at most oriented onto the Java Archives.

Java Source File

πŸ“Œ Most often, the .J container group is eligible for maintenance, handling, and processing of the program source code written and composed on the Java programming specification. Accurately, the .J modules and elements may consist of the source code for an entire program solution or may be one of multiple items referenced by the Java programming layout. Nevertheless, typically all of the Java source entries and records are marked with the .JAVA extension tag.

JPEG Image

β‡’ Category:Raster Image Files

πŸ“Œ In conclusion, the .J layout composition may rely on the compressed graphic that utilizes .JPEG image encoding algorithm. Precisely, the noted .J schema may include thousands of color tones, which makes the following .J format approach a perfect solution for storing pictures and digital photos. Therefore, the current .J algorithm may utilize different levels of compression. However, the more solid the degree of compression applied, the worse is the final quality of the outcome graphic elements and items.

How to open an .J file?

πŸ“Œ The .J entry content can be unpackaged, extracted and opened by Oracle Java Virtual Machine, Vim, Eclipse IDE, or console javac utility responsible for compiling Java .J embraced source code into an executable form. Besides, considering the situation when the peculiar .J file structure is comprehended as a compressed file entity, it is recommended to make use of ARJ Software JAr archiver, released in the former years. Finally, it may occur that the target .J elements are distinguished as graphical pictures or images, and therefore can be opened, reviewed, and sustained by any picture viewer or web-browser, pre-installed within your working infrastructure.
