How to Generate a Jimple File

[75ACOL]

Good morning, please give me a test case. I have been searching for it for a long time but could not find it in sootup.

Here is an example of how to extract the Jimple code of a SootClass into a string:

StringWriter stringWriter = new StringWriter();
PrintWriter writerOut = new PrintWriter(stringWriter);
Printer printer = new Printer();
printer.printTo(sootClass, writerOut);
writerOut.flush();
String jimpleOfSootClass = stringWriter.toString();

Or you can simply call sootClass.print() on the SootClass to obtain the Jimple representation as string.
