The Java.io.File class is an abstract representation of file and directory pathnames. Following are the important points about File:
Instances may or may not denote an actual file-system object such as a file or a directory. If it does denote such an object then that object resides in a partition. A partition is an operating system-specific portion of storage for a file system.
A file system may implement restrictions to certain operations on the actual file-system object, such as reading, writing, and executing. These restrictions are collectively known as access permissions.
Instances of the File class are immutable; that is, once created, the abstract pathname represented by a File object will never change.
JAR stands for JAVA Archive File. You can archive a number of java class files into an archive and form a JAR. If you place the JAR in a particular location in the computer and then add the path to the JVM Class path, the JVM will be able to recognize references to classes that are present in the JAR.
SIS files are Symbian and JAR files are java. The software that converts a SIS file to a JAR file is called Sis to Jar Converter 1.7.7.2.
.jar files contain byte-code compiled to run on the Java Virtual Machine.
this conversion is not possible because sis is a symbian file(another operating system that is mainly used by nokia) & jar is java file both are not same
you can play the jar files by transfer it in to nokia mobile phones
Jar file is Java AR-chive Java Archive File, commonly referred to as a Jar File is nothing more than a compressed archive file.
You can change the file extension from .txt to .jar but .jar is a java format and is not normally used to wrap text.
JAR stands for JAVA Archive File. You can archive a number of java class files into an archive and form a JAR. If you place the JAR in a particular location in the computer and then add the path to the JVM Class path, the JVM will be able to recognize references to classes that are present in the JAR.
Depends on what you mean by "work". For one thing, a jar is a Java archive file, not a folder.
the short answer is that it does. assuming you have java installed and your path set, it's as easy as javac javafilename.java java javafilename or if you have it as a jar file java -jar jarfilename.jar
You must have a java runtime environment (JRE) installed to run a jar file .. if it is not a jar ( or it is a class ), you should have the java development kit or JDK .. if the file you are running is a jar file, just double click it. if the file you are running is a class file ex. "MainProg.class" then go to the bin directory, and open command prompt and change to that directory. then java MainProg.class it should run ..

You can open jar files with command prompt, Winrar or java.

The Java Archive (JAR) file format enables you to bundle multiple files into a single archive file and Typically a JAR file contains the class files and auxiliary resources associated with applets and applications
