Standard output when calling a method from a jar

Question

I have a question about obtaining standard output from a call to a method in a jar. I understand that a) and b) below are equivalent, but how do I get the output that the java call produces when I call SugarMain.decode in a java program? In other words, where does the output from SugarMain.decode go and is that equivalent to the standard output from the java SugarMain -decode call? I obtained the jar from http://bach.istc.kobe-u.ac.jp/sugar/ which has no user support.
Thank you,
Richard Becraft
a) SugarMain.decode("sugar5400.out", "sugar5400.map");
b) java SugarMain -decode sugar5400.out sugar5400.map
java SugarMain -decode sugar5400.out sugar5400.map

Answer 1

Without knowing anything about SugarMain it is difficult to answer your question.
It may help to know that there is nothing inherently different about classes referenced from jar files then classes referenced from loose class files. The specifies on how to get the output of SugarMain.decode() is dependent on SugarMain.decode().
You say that there is no user support but is there any documentation or source files or samples. If the answer is "No" to all of those, it may be that you lose.
