Pegasus Posted March 26, 2019 Share Posted March 26, 2019 (edited) What are the possible reason programs not work after removed printing variables lines? Programs work after I recover the printing variables lines. e.g System.out.println("Print someArrayList.size(): " + someArrayList.size() ); Edited March 26, 2019 by Pegasus Quote Link to comment Share on other sites More sharing options...
HeyImJamie Posted March 26, 2019 Share Posted March 26, 2019 Need a little more context. We can't magic up reasons why your program doesn't work. Quote Link to comment Share on other sites More sharing options...
