    Default how to compile and execute java package ie., csv comparator

    Hi I am Rupesh from India and I have some csv files and I want to compare these files and so I have found a nice software called csvcomparator which is written in java. I have downloaded it from sourceforge and found jar files and .class files and I don't how to compile and run it.

    At present along with opensuse leap 42.2 I have installed main packages under development including gcc,gcj,jar etc, but I have not installed eclipse.

    The software I have downloaded is a zip file which contains jar file names which consists eclipse word.Is it necessary to install eclipse package for my need I am asking because the downloaded package may take around 200 mb and installation may take around 500 mb which I don't want.

    I am providing the contents of zip file below

    Code:

    The package contains gui mode and cli mode and I want to use gui mode.

    I want to run this package I mean I want to compare two csv files but as I am not programmer please suggest how to do so.

    Is there any other easy way to compare two csv files.
    Regards,
    Rupesh.

    JAR files are already compiled.
    Just run something like the following
    Code:
    java application.jar
    If you need to compile anything, then you will need a compiler.
    Eclipse is what is known as an IDE which is a comprehensive tool to code, debug and compile.
    If you're not coding, unless the code is in the form of an Eclipse project you won't need that.
    Instead, if you only need a compiler... You can use the compiler app called Ant... I'm sure it's in the openSUSE repos.
    In fact, Eclipse typically uses Ant to compile Java code.

    But... The very first thing you should actually do is take a look at the source files and look for text files like INSTALL and README. Typically those files can provide you with comprehensive descriptions of the files and what to do with them. "contents.txt" and "example" might be good candidate files from what you posted.

    Some of the files in package contains the word eclipse and so can I think it is an eclipse project.

    Jar files are executable like .exe. In order to execute jar files we need to install latest version of java sdk and latest version of eclipse if possible. In order to run jar file just double click on the file and do not try to extract it.

    Rupesh.

    I wasn't going to try to read each individual branch of the files described (BTW - For anyone who would want to do something like that, instead of what the OP did, use the "tree" command instead to list all the files in a graphical manner which is visually easy to understand).

    It should not make any difference if the files are actually an Eclipse project,
    It's common (but not always practiced) for the owner of a Project to distribute not just the source but the last compilation.

    I can't remember if I've ever double-clicked on a JAR file to execute it, maybe when running in some Desktop environments that's supported. But generally, I've always used the full "java JAR" command because like other executables I often need to specify options, flags, and sometimes additional attributes and parameters.

    like tsu2 said those are already compiled files (if they wore uncompiled their extension would be *.java)
    the *eclipse*.jar files look like are java libraries (kind of like *.dll files under windows or *.so for Linux)
    to run java apps you need a java runtime opensuse provides several and afaik openjdk 1.8 should already be installed
    if there is no readme file in the zip the thing to do is unpack the content of that archive and execute
    Code:
    java -jar CSVComparatorGUI_java8_64bit.jar
    not when calling *.jar files you need the -jar switch
