Unzip all file without it's folder using Java

Question

Is it possible to unzip all files from the zip folder without its folder?

Example:

zipfolder.zip has two subfolders called folder1(having files like 1.txt, 2.xlsx, 3.pdf) and folder2(having files like 4.txt, 5.pdf)

Note: The source can any type of archive files like .zip, .rar, .tar, .7-zip etc

This is my code:

String sevenZipLocation = "C:\\Program Files\\7-Zip\\7z.exe";
String src = source filepath (zip file)
String target = output path (output path)

String[] command={sevenZipLocation,"x",src,"-o"+target,"-aou","-y"};

ProcessBuilder p = new ProcessBuilder( command );
Process process = p.start();

InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);

@SuppressWarnings("unused")
String line;

while ((line = br.readLine()) != null){
    System.out.println("line1 "+line);
}
process.waitFor();

When I execute this code the output like

unzip folder ----- folder1(having files like 1.txt, 2.xlsx, 3.pdf) and folder2(having files like 4.txt, 5.pdf)

But I want to extract the only file from all folders and the output like 1.txt, 2.xlsx, 3.pdf, 4.txt, 5.pdf in the output path.

Is there any command for that. Thanks.

All you need to change:

String[] command={sevenZipLocation,"e",src,"-o"+target,"-aou","-y","*.*","-r"};

PS. I don't think Java is the best choice to run OS commands. You'll be wasting a lot of time. But if you insist, don't forget there might be an errorstream too.
