Longman Dictionary of Contemporary English
JAR is a tool for creating compressed file archives that use .j as their file extension. It was invented by Robert K. Jung and was meant to be a successor to ARJ. It can achieve very good compression, but is not in wide use. JAR should not be confused with the .jar file extension used for Java Archive files, which are actually zip files with some embedded metadata.
A jar was an early unit of capacitance once used by the British Royal Navy. The term originated as the capacitance of a Leyden jar. Its value is such that one farad is jars and one jar is 1111 picofarads.
Jar is the debut studio album by American band Superheaven, released on April 30, 2013. It was originally released under the band's prior name, Daylight, which has since been changed due to a legal dispute.
JAR (file format)
In software, JAR (Java Archive) is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file to distribute application software or libraries on the Java platform.
JAR files are fundamentally archive files. They are built on the ZIP (file format) and have the .jar file extension. Computer users can create or extract JAR files using the jar command that comes with a JDK. They can also use zip tools to do so, however the order of entries in the zip file headers is important when compressing, as the manifest often needs to be first. Inside a JAR, file names are Unicode text.
A jar is a rigid, approximately cylindrical container with a wide mouth or opening. Jars are typically made of glass, ceramic, or plastic. They are used for foods, cosmetics, medications, and chemicals that are relatively thick or viscous: pourable liquids are more often packaged in a bottle. They are also used for items too large to be removed from a narrow neck bottle.
Glass jars can be used for home canning and food preservation. They can be used to preserve or store items as diverse as jam, pickled gherkin, other pickles, marmalade, sundried tomatoes, olives, jalapeño peppers, chutneys, pickled eggs, honey, and many others. They are also frequently re-used in order to put home-made preserves in. Jars are sterilised by putting them in a pressure cooker with boiling water or an oven for a number of minutes. If they are not required for further storage of items, they can be recycled.
A closure applied to the mouth of a jar can be a screw cap, lug cap, cork stopper, or other suitable means.
Glass jars are considered microwavable with care taken to prevent splashing of boiling contents
Jars are often recycled according to the SPI recycling code for the material. Some regions have a legally mandated deposit which is refunded after returning the container to the retailer. Some recyclers have concerns about possible residue in the jar from the viscous contents.
Jar is a station served both by the Oslo Metro and the Oslo Tramway located in Bærum, just west of Lysakerelva which divides Oslo and Bærum. The track is shared, the tram line ( Lilleaker Line) joins with the rapid transit line ( Kolsås Line) on the Oslo side of the river. The station's penthouse is yellow and contained a newspaper outlet.
Formerly, the entire line to Kolsås was part of the tram network. Since 2 December 2007 tram operations (line 13) have returned on this line from Jar to Bekkestua. Some tram runs, usually with SL79 units, run only as far as Jar where there is the turning loop they require.
As of December 2010, the Tram line 13 is running alternative trams (every 20 minutes) to Jar. The Oslo Metro line 3 also runs with an interval of every 15 minutes.
