java - What is wrong with this nested for loop? -
this question has answer here:
i cannot life of me work out why nested loop isn't working.
public void getmagsabovex(double minimummag) { for(observatory myobservatory : monitoring) { for(earthquake myearthquake : earthquakes) { if(myearthquake.returnmagnitude() > minimummag) { system.out.print(myearthquake.returnmagnitude() + ", "); } } } }
i error "cannot find symbol - variable earthquakes" far know earthquakes name of second arraylist want iterate through. if change 'earthquakes' arraylist() error "-> expected". don't know doesn't like.
first : in javadoc comments methods methods "return" something. don't though. both methods void
.
and long call getmagsabovex(minimummag)
on object of type observatory inside listmagsabovex
method, don't see fail.
you should post full methods if want more though.
