so i've attached debugger, , tried different inputs , can't seem figure out why won't past loop. when ran enter "l" or "l", entry gets set that, input set capitalized version , repeats.
public static char displaymenu(){ char input; sc.nextline();//clear junk { system.out.println(); system.out.println("\t\t enter l (l)oad "); string entry = sc.nextline(); input = entry.touppercase().charat(0); } while (input != 'l' || input!='m' || input != 'p' || input != 'q');
your boolean || incorrect. if value l not m, p or q loop continue iterate. think wanted like,
while (input != 'l' && input != 'm' && input != 'p' && input != 'q'); or
while (!(input == 'l' || input == 'm' || input == 'p' || input == 'q')); consider when input l, l not m , initial while condition continue iterate.
