swing - Java Program says that sound file is not there -
i coding piano in java , used have entire class where, when note pressed specific method in class called specific note. in order shorten code (still working on part), used integers of boolean array made decide note. example, if boolean[1] set true, i'd call method integer , based on integer, string set name of sound file. problem having says file not there, , know fact is. can me out here?
