How to get the contents of an InputStream?

Question

I use the following method to get all .class files from an eclipse project. but the returned files are in InputStream format which I can not get the content.

public void setFileList(IContainer container) throws CoreException, IOException {
       IResource [] members = container.members();

       for (IResource member : members) {
          if (member instanceof IContainer)  {
              setFileList((IContainer)member);
           } else if (member instanceof IFile && member.isDerived()) {
               IFile file = (IFile)member;

               InputStream contents = file.getContents();
               this.fileList.add(contents);
           }
        }
    }

How can I get the contents of this InputStream in a string format or a txt file?

This returns me java.io.FileInputStream@7fbd1f7d and not the file — , May 03 '18 at 12:40
In this question that was pointed out I could not understand because I do not know what I have to put into encoding — , May 03 '18 at 12:44
Class files are binary not text. So what kind of text do you expect for class files? — vanje, May 03 '18 at 15:39

If you want to write it into a file then you can directly use apache.commons.io helper method:

final File outputFile = new File("test.txt");
FileUtils.copyInputStreamToFile(inputStream, outputFile);
