java - Simultaneous movement of two graphics with different and changing text -
the code wrote giving different output required.
output got:
in upper movement yellow rectangle moves left right in steps. in each step text changes 1 (signal 1, signal 2, signal 3 etc.)
in lower movement text moves left right (at higher speed yellow rectangle above).
text in both (above , below it) remains same i.e. if above "signal 1", below "signal 1", if above "signal 2" below same "signal 2". , on.
output required:
every thing should remain except: 1. in lower movement need text in green rectangle (same yellow rectangle above). 2. in lower movement need text of higher 2 in loop. in other words,
if above "signal 1" below should "signal 3". if above "signal 2" below should "signal 4". if above "signal 3" below should "signal 5". if above "signal 4" below should "signal 6". if above "signal 5" below should "signal 7". if above "signal 6" below should "signal 8". if above "signal 7" below should "signal 9". if above "signal 8" below should "signal 10". if above "signal 9" below should "signal 1". if above "signal 10" below should "signal 2". being new programming , java need required output. in anticipation. complete working code is:

looks homework me. don't understand approach of giving students pile of code don't understand instead of making them code scratch. also, naming "drawingpanel" pretty bad. might better off studying programming reading on internet course material that.
instead of adding width2 etc. drawingpanel, supposed create 2 of them; 1 each box text in it.
