如何从url或path（目录）中描述jtable中文件rar / zip的内容？

Question

How to describe content of file rar/zip in jtable from url or path directory in java?
I found here and here
But how to open from URL on describe to jtable?

Answer 1

I'd use PrpcessBuilder , shown here , to execute unzip -l or unrar -l and parse the output to create my TableModel . See also How to Use Tables .

Answer 2

You need to model the data some how. Maybe a VirtualFile , this should contain the information you want to display.

You then need to create a model of the that wraps this data in some meaningful way. You'll need a TableModel for this purpose (preferably use the Abstract or Default implementation)

Once you've decided on how you want the model to be laid out, you simply supply the modle to the JTable

UPDATE

You can learn more from the Basic I/O lesson , but here's a (really) basic example of reading the contents of URL to local disk

File outputFile = new File("Somefile on disk.rar");
Inputstream is;
OutputStream os;
try {
    is = url.openStream();
    os = new FileOutputStream(outputFile);

    byte[] buffer = new byte[1024];
    int bytesIn = -1;
    while ((bytesIn = is.read(buffer)) != -1) {

        os.write(buffer, 0, bytesIn);

    }

    os.flush();
} catch (IOException exp) {
    exp.printStackTrace();
} finally {
    try {
        is.close();
    } catch (Exception exp) {
    }
    try {
        os.close();
    } catch (Exception exp) {
    }
}
